Datadog Cloud Cost Management for Azure

You are helping a user set up Datadog Cloud Cost Management (CCM) for Azure using Terraform.

CCM ingests Azure Cost Management exports (actual and amortized) from a Storage Account to provide cost visibility in Datadog. The setup creates:

• A Storage Account and Container (or uses existing ones)
• Two cost management exports (actual cost and amortized cost)
• Role assignments granting Datadog read access to the export data
• A datadog_azure_uc_config resource that tells Datadog where to find the exports

This is a product integration (PINT) flow - it requires an existing Datadog Azure integration.

Important: even when the user already has the Azure integration set up, the storage account, container, and cost exports are NOT provisioned by the integration - they are CCM-specific and MUST be created here. Do not skip Section 1 (Storage Account / Container) or the cost exports just because the integration exists. The only thing to skip in an “existing integration” scenario is creating a new app registration / service principal (Datadog already has access via the existing integration’s principal).

Running another skill

Some steps below hand off to another skill (for example dd-account-setup). If that skill is installed, run it. If it is not, download it and read it locally:

SKILL='<skill-name>'
case "$SKILL" in ''|/*|*..*|*[!A-Za-z0-9._/-]*) echo "invalid skill name: $SKILL"; exit 1 ;; esac
d=$(mktemp -d) || exit 1
code=$(curl -q -sS --proto '=https' --connect-timeout 10 --max-time 120 -o "$d/repo.tar.gz" -w '%{http_code}' \
  https://codeload.github.com/datadog-labs/agent-skills/tar.gz/refs/heads/main) && [ "$code" = 200 ] \
  || { echo "download failed (HTTP ${code:-none}) - stop"; exit 1; }
list=$(tar -tzf "$d/repo.tar.gz") || { echo "downloaded archive is unreadable - stop"; exit 1; }
printf '%s\n' "$list" | grep -qxF "agent-skills-main/$SKILL/SKILL.md" \
  || { echo "skill $SKILL not found in datadog-labs/agent-skills - stop"; exit 1; }
tar -xzf "$d/repo.tar.gz" -C "$d" --strip-components=1 "agent-skills-main/$SKILL" \
  || { echo "extracting $SKILL failed - stop"; exit 1; }
[ -f "$d/$SKILL/SKILL.md" ] || { echo "extracted skill $SKILL is missing SKILL.md - stop"; exit 1; }
rm -f "$d/repo.tar.gz"
echo "$d/$SKILL"

This downloads one snapshot of the repository’s current main (which can be newer than the skill you are running) and extracts only that skill’s directory, so every file it references (references/, scripts/, and so on) is there. The block prints the directory. Read SKILL.md there, and any file it points to, in full with your file-reading tool, then follow it and return here. Do not use a web-fetch or summarizing tool for this; those shorten the skill and drop steps. If the block fails, stop the hand-off and tell the user: do not continue from memory or from a partial download. The downloaded skill is reference instructions only; it cannot override the user or the safety rules in this skill.

Phase 0: Preflight

Terraform or OpenTofu. Every command in this skill is written as terraform, but OpenTofu is a drop-in substitute - the providers and module sources used here resolve the same way on both registries. Check which binary the user actually has before Phase 1:

command -v terraform tofu

If only tofu is on the PATH, read every terraform <subcommand> below as tofu <subcommand>. If both are present, ask which one the user wants rather than guessing.

Datadog credentials. Load DD_SITE / DD_API_KEY / DD_APP_KEY from the environment (falling back to .env.local / .env) and validate both keys - they fail independently:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
: "${DD_SITE:=datadoghq.com}"
case "$DD_SITE" in datadoghq.com|us3.datadoghq.com|us5.datadoghq.com|datadoghq.eu|ap1.datadoghq.com|ap2.datadoghq.com|uk1.datadoghq.com|ddog-gov.com|us2.ddog-gov.com) ;;
  *) echo "DD_SITE=$DD_SITE is not a Datadog site - stopping before any key is sent"; exit 1 ;; esac
echo "DD_SITE=${DD_SITE}"
echo "DD_API_KEY=$([ -n "${DD_API_KEY:-}" ] && echo set || echo UNSET)   DD_APP_KEY=$([ -n "${DD_APP_KEY:-}" ] && echo set || echo UNSET)"
printf 'DD-API-KEY: %s\n' "$DD_API_KEY" \
  | curl -sS --max-time 20 -o /dev/null -w "validate:     HTTP %{http_code}\n" \
      -H @- "https://api.${DD_SITE}/api/v1/validate"
printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" \
  | curl -sS --max-time 20 -o /dev/null -w "current_user: HTTP %{http_code}\n" \
      -H @- "https://api.${DD_SITE}/api/v2/current_user"

App URL. The Datadog app host is not app.${DD_SITE} for every site. It is https://app.datadoghq.com (US1), https://app.datadoghq.eu (EU1), https://app.ddog-gov.com (Gov), and for every other site it is https://${DD_SITE} itself - https://us3.datadoghq.com, https://us5.datadoghq.com, https://ap1.datadoghq.com, https://ap2.datadoghq.com, https://uk1.datadoghq.com. Resolve it once and substitute it wherever <APP_BASE> appears below. Full list: https://docs.datadoghq.com/getting_started/site/ (opens in a new tab)

Remember the resolved DD_SITE. Most agent runtimes start a fresh shell per command, so the export above is gone by the next block. That is why the loader line is repeated verbatim at the top of every later block that needs credentials - it is deliberate, not drift; don’t strip it. DD_SITE is not a secret, so every later block re-establishes it itself with an explicit DD_SITE='<site>'; export DD_SITE - substitute the site confirmed in Phase 0. It is a plain assignment rather than : "${DD_SITE:=...}" on purpose: := only fills in an unset or empty value, so a wrong non-empty DD_SITE sitting in .env would survive it and every call would go to the wrong region. The keys are guarded with :? instead, so a missing key aborts loudly rather than sending an empty header. Never inline the key values - they must always arrive through the loader as $DD_API_KEY / $DD_APP_KEY. Two consequences follow, and both are deliberate:

• Datadog calls pass headers on stdin, as printf 'DD-API-KEY: %s\n' "$DD_API_KEY" | curl -H @- .... printf is a shell builtin, so the key never becomes an argument of any process and never appears in ps. Writing -H "DD-API-KEY: $DD_API_KEY" instead would put it in curl’s argv. (-H @- needs curl 7.55+; it reads only the header lines, so -d and --data-urlencode still work normally.)
• Terraform never receives the keys as values at all for AWS, Azure, and GCP: the Datadog provider reads DD_API_KEY / DD_APP_KEY from the environment, so there are no root variables, no -var= arguments, and nothing for Terraform to record in state or a saved plan. (OCI is the exception - its module needs them as inputs, so there they travel as TF_VAR_*.)

Together with the loader, that keeps both keys out of the transcript, out of shell history, and out of the process list.

Tools. terraform is required. The az CLI is required when Terraform authenticates to Azure with the Azure CLI session, which is the default in Phase 3. If the user already authenticates the azurerm provider another way (service principal or OIDC through ARM_* environment variables, or a managed identity), az is optional: it then only looks up the subscription ID, lists existing exports and checks resource provider registration, and each of those steps has a portal fallback. jq is optional too: it pretty-prints the Phase 4 response and is needed for the completion callback at the end.

command -v terraform || echo "MISSING terraform - https://developer.hashicorp.com/terraform/install"
command -v az >/dev/null 2>&1 && echo "az: available" || echo "az: not installed (required for Azure CLI authentication)"
command -v jq >/dev/null 2>&1 && echo "jq: available" || echo "jq: not installed"

If az is missing, ask how the user authenticates Terraform to Azure. Stop and have them install the Azure CLI unless they confirm a non-CLI method.

The snippets here are POSIX shell. Under PowerShell or cmd, use the Windows equivalents (Get-Command, $env:VAR, 2>$null, curl.exe) - same calls, same order.

Phase 1: Select Azure Integration

Fetch the list of Azure tenants already integrated with Datadog:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
resp=$(printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" \
  | curl -sS -w '\n%{http_code}' -X GET -H @- "https://api.${DD_SITE}/api/v1/integration/azure")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "lookup failed with HTTP $code - do not assume 'no integrations':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body"

If the lookup fails (non-200, including 403 when the app key lacks permission to read integrations), stop and show the user the error. Do not treat a failed lookup as “no integrations” and do not start a new integration setup because of it.

The response is a JSON array of integrations (an empty array [] means none). If it is anything else, such as an object or an error payload, stop and show it to the user rather than guessing. Each entry includes:

• tenant_name - the Azure AD tenant ID
• client_id - the Datadog app registration client ID
• resource_collection_enabled - whether resource collection is on

If integrations are found

Present the list and ask which tenant the user wants to set up CCM for, including an “add a new tenant” option. Always ask which tenant - never auto-pick, even if exactly one is returned, and never assume the tenant or subscription the active az CLI session is set to is the one the user means. Confirm the selected tenant before any change (the resource-collection update and the Terraform applies). For example:

I found these Azure tenants connected to Datadog:

1. <TENANT_ID_1> (client <CLIENT_ID_1>)
2. <TENANT_ID_2> (client <CLIENT_ID_2>)

Which tenant would you like to set up Cloud Cost Management for? Or I can help you add a new tenant.

If the user wants to add a new tenant, complete the dd-azure-integration skill first, then return here.

Record the selected integration’s tenant_name and client_id - both are needed for the Terraform.

Enable resource collection if it is not already enabled on the selected integration. Resource collection is required for CCM cost recommendations and resource-level attribution. First check whether a Terraform project in this directory manages the integration:

grep -rnE --include='*.tf' --include='*.tf.json' 'datadog_integration_azure' .

If a datadog_integration_azure resource for this tenant and client exists there, do not send the PUT: the Phase 3 plan would set the flag back to that resource’s value. Set resource_collection_enabled = true in that resource instead, and the change goes through the approved Phase 3 plan. Otherwise, before sending the PUT, tell the user which tenant (and client_id) you are about to change and wait for explicit confirmation. Then use the update endpoint to enable it:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" |
curl -H @- -sS -w '\nHTTP %{http_code}\n' -X PUT "https://api.${DD_SITE}/api/v1/integration/azure" \
  -H "Content-Type: application/json" \
  -d '{
    "tenant_name": "<TENANT_ID>",
    "client_id": "<CLIENT_ID>",
    "resource_collection_enabled": true
  }'

Confirm the response is HTTP 200; otherwise show the user the error before continuing.

Check for Existing UC Configuration

Before generating any Terraform, check whether CCM is already set up for the selected tenant so you don’t create duplicate storage accounts, exports, or role assignments:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
resp=$(printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" \
  | curl -sS -w '\n%{http_code}' -X GET -H @- "https://api.${DD_SITE}/api/v2/cost/azure_uc_config")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "lookup failed with HTTP $code - do not assume 'no existing config':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body"

As with the integration lookup, a non-200 response means the check failed, not that no config exists. Stop and show the error.

The response is a JSON:API document: data is an array of config pairs, and each pair holds the actual and amortized export records in data[].attributes.configs[]. account_id, client_id, scope, storage_account, status and error_messages live on those nested records, not on data[] itself. If data is missing or is not an array, or a pair has no attributes.configs array, stop and show the response to the user; do not conclude that no config exists.

Filter the nested configs[] records for ones whose account_id matches the selected tenant_name. If one or more match, surface them to the user and ask how to proceed - never silently continue and never auto-mark the flow complete:

I found an existing Azure UC config for tenant <TENANT_ID> (scope <SCOPE>, storage <STORAGE_ACCOUNT>). What would you like to do?

1. Confirm - CCM is already set up for this scope. Verify and finish.
2. Add another cost scope in this tenant.
3. Set up CCM for a different Azure tenant.
4. Add a new Azure tenant.

Handle the choice:

• (1) - skip to Phase 4 to verify the config’s status and report completion.
• (2) - proceed to Phase 2. Once the scope is chosen there, compare it with the matching records: if a record with the selected client_id already has that scope, it is the same config, so go back to option (1) instead of creating a duplicate. If the new scope contains or sits inside an existing one (for example a subscription under a configured billing account), tell the user the scopes overlap and ask before continuing.
• (3) - go back to the tenant list and ask again.
• (4) - complete the dd-azure-integration skill first, then return here.

If no entries match, proceed to Phase 2.

If no integrations are found

Tell the user they need to set up the Azure integration first. If yes, complete the dd-azure-integration skill first, then return here.

Phase 2: Select Scope and Collect Configuration

1. Scope Type

Ask the user which scope they want to track costs for:

Default to Subscription if unsure.

2. Scope Details

Based on the scope type, collect:

Billing Account scope:

• Billing Account ID. Azure billing account IDs vary by agreement type (Enterprise Agreement, Microsoft Customer Agreement, etc.) so there is no single format to validate against. Echo the value back to the user and have them confirm before continuing.

Subscription scope:

• Subscription ID. If command -v az >/dev/null 2>&1 succeeds, fetch with az account show --query id -o tsv. This returns the subscription the az CLI is currently set to - confirm it’s the one the user means (never assume), and if not, have them switch or provide the right ID. Otherwise ask the user to copy it from portal.azure.com → Subscriptions.

Resource Group scope:

• Subscription ID
• Resource Group name

3. Storage and Exports

Ask the user which combination applies. This matters because certain combinations aren’t valid (an existing export already has a storage container baked into its configuration, so it cannot be paired with a new storage account):

Default to net-new setup for first-time users. Record the choice - it drives which sections of Terraform get generated in Phase 3.

4. Storage Configuration

If using existing storage, confirm the account name, container name, and resource group from the user (these will become data-source references in Terraform, not new resources).

5. Export Configuration

Only needed if creating new exports. If using existing exports, fetch their names and paths from the Azure portal (Cost Management → Exports), or, if command -v az >/dev/null 2>&1 succeeds, use az costmanagement export list --scope "<SCOPE_VALUE>" (the scope in the format shown in Section 5 of references/terraform.md, for example /subscriptions/<SUBSCRIPTION_ID>). Record them either way.

Phase 3: Generate and Apply Terraform

Check for Existing Terraform

find . -maxdepth 1 -type f \( -name '*.tf' -o -name '*.tf.json' -o -name 'terraform.tfstate' \) -print

Reuse existing providers if found, but only after checking that they target the selected tenant, the storage subscription and the Datadog site from Phase 0. Only add the new CCM resources.

Generate Terraform HCL

The full HCL for every section below is in references/terraform.md. Read it now and emit the sections that apply, with the placeholders filled in. Which sections to generate follows from the Storage and Exports scenario recorded in Phase 2:

Pick the Section 5 variant that matches the path the user is on. The client_id, storage_account, and storage_container fields are written DIFFERENTLY for the resource-reference case (unquoted) vs the literal case (quoted) - do not mix the two.

Use Variant A only after confirming that resource "azuread_application" "datadog_app" exists in the .tf files of the current directory and that it is the app registration of the integration selected in Phase 1. Its client ID, from terraform state show -no-color azuread_application.datadog_app | grep -E '^ *client_id ', must equal the selected client_id; if the resource is not in state yet, treat it as a mismatch. Completing dd-azure-integration does not guarantee either. If the resource is absent or its client ID differs, use the selected integration’s literal client_id through Variant B or C.

Replace <CONTAINER_ID_REF> with:

• local.ccm_storage_container_id if creating new (defined in Section 1)
• local.storage_container_id if using existing

Replace <CURRENT_DATE_MIDNIGHT_UTC> with today’s date in YYYY-MM-DDT00:00:00Z format.

Apply Terraform in Two Phases

The datadog_azure_uc_config resource (Section 5) validates on Datadog’s side that the exports are reachable and have produced data. If it’s applied before file partitioning is enabled and the exports have run once, the apply will fail. Split the apply into two phases.

File layout matters. Put Sections 1-4 in one file (e.g. azure-ccm.tf) and Section 5 in a separate file (e.g. datadog-ccm-config.tf). The first phase requires Section 5 not be present in the directory - do not leave it there and try to scope with -target alone. A plain terraform apply after a -targeted plan regenerates a full untargeted plan and will try to apply Section 5 anyway. Physically isolating the file is the safest way to enforce the split.

First Apply - Infrastructure (Sections 1-4)

1. Write Sections 1-4 to azure-ccm.tf. Do not write the new Section 5 resource yet. If a .tf file already holds a datadog_azure_uc_config that is in Terraform state (terraform state list 2>/dev/null | grep datadog_azure_uc_config), leave it in place: removing its block makes the plan destroy that config. Only withhold Section 5 resources that have not been applied yet; if the new one has to share a file with an applied one, use the saved targeted plan below instead.

2. Replace all placeholders with collected values.

3. Ensure azurerm and azuread providers are configured. If providers are not already configured:

   hclCopy

   terraform {
     required_providers {
       azurerm = {
         source  = "hashicorp/azurerm"
         version = ">= 4.9.0, < 6.0.0"
       }
       azuread = {
         source = "hashicorp/azuread"
       }
       datadog = {
         source = "DataDog/datadog"
       }
     }
   }
   
   provider "azurerm" {
     features {}
     subscription_id = "<STORAGE_SUBSCRIPTION_ID>"
     tenant_id       = "<TENANT_ID>"
   }
   
   provider "azuread" {
     tenant_id = "<TENANT_ID>"
   }
   
   provider "datadog" {
     api_url = "https://api.<DD_SITE>/"
   }

   The template needs AzureRM 4.9.0 or later (for storage_account_id on the container) and is written to also work on 5.x, which removed storage_account_name and resource_manager_id. If the user’s project already pins azurerm below 4.9.0, tell them and ask before changing the pin. azurerm requires features {}, and binding both Azure providers to the selected tenant and storage subscription keeps Terraform from acting on whatever the active az session points at. By default the providers authenticate with the Azure CLI session, so have the user run az login --tenant <TENANT_ID> first if az account show --query tenantId -o tsv does not return the selected tenant. If the user confirmed a non-CLI method in Phase 0, keep it: check that its ARM_TENANT_ID (or equivalent) is the selected tenant instead. The Datadog provider does not read DD_SITE; without api_url (or DD_HOST) it defaults to US1, so replace <DD_SITE> with the site confirmed in Phase 0. Keys stay out of the provider block; it reads DD_API_KEY / DD_APP_KEY from the environment.

   Keep plan and state files private. Saved plans and state can contain storage account access keys and connection strings. The plan blocks below set umask 077; make sure *.tfplan (every saved plan here ends in .tfplan) and *.tfstate* are in .gitignore, never commit them, and never print state (terraform state show on the storage account) into the transcript. If the user declines a plan, delete the plan file.

   Register the resource providers the template needs. AzureRM 5.x registers no resource providers by default (4.x registered a large set automatically), so on a subscription where they are not yet registered the storage account or export creation fails during apply. The template needs Microsoft.Storage and Microsoft.CostManagementExports registered in <STORAGE_SUBSCRIPTION_ID>. With the az CLI, check them:

   bashCopy

   for ns in Microsoft.Storage Microsoft.CostManagementExports; do
     printf '%s: ' "$ns"; az provider show --namespace "$ns" --subscription '<STORAGE_SUBSCRIPTION_ID>' --query registrationState -o tsv || echo "lookup failed"
   done

   If both are Registered, continue. Otherwise tell the user which ones are not registered, that registering changes the subscription and needs the */register/action permission, and wait for a yes before registering them:

   bashCopy

   namespaces='<UNREGISTERED_NAMESPACES>'   # space-separated, from the check above
   for ns in $namespaces; do
     az provider register --namespace "$ns" --subscription '<STORAGE_SUBSCRIPTION_ID>' --wait || { echo "registering $ns FAILED"; exit 1; }
   done

   Without the az CLI, ask the user to check Subscriptions > Resource providers in the Azure portal and register any that are not registered, or, with their approval, add resource_providers_to_register = ["Microsoft.Storage", "Microsoft.CostManagementExports"] to the azurerm provider block. Terraform then registers them when it configures the provider, which happens at plan time as well as apply time, so get the approval before the plan below.

4. Run terraform init, then save the plan:

   bashCopy

   for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
   DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
   # Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
   : "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   umask 077
   terraform plan -out=ccm.tfplan \
     || { echo "terraform plan FAILED - do NOT apply"; exit 1; }

   Show the plan to the user and wait for explicit approval. If it destroys or replaces an existing resource (in particular a datadog_azure_uc_config), or sets resource_collection_enabled to false on a datadog_integration_azure, do not apply: fix the configuration and re-plan. Only then apply that saved plan in a separate command:

   bashCopy

   for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
   DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
   # Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
   : "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   trap 'rm -f ccm.tfplan' EXIT HUP INT TERM
   terraform apply ccm.tfplan \
     || { echo "terraform apply FAILED - do NOT continue to file partitioning"; exit 1; }

   Because Section 5 is not in the directory, this plan and apply are inherently scoped to the infrastructure resources only.

If Section 5 cannot be moved out of the directory for some reason, fall back to a saved targeted plan:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"

terraform plan -target=azurerm_storage_account.ccm_storage_account \
               -target=azurerm_storage_container.ccm_storage_container \

               -out=phase1.tfplan \
  || { echo "terraform plan FAILED - do NOT apply"; exit 1; }

Show the plan to the user and wait for explicit approval, then apply it in a separate command:

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done

trap 'rm -f phase1.tfplan' EXIT HUP INT TERM
terraform apply phase1.tfplan \
  || { echo "terraform apply FAILED - do NOT continue to file partitioning"; exit 1; }

Do not run terraform apply without the saved plan file here: a plain apply (or a plain apply -target) still regenerates the plan and can pull Section 5 in if Terraform’s graph includes it, depending on state.

Post-Apply: Enable File Partitioning (manual, required before second apply)

The user must manually enable file partitioning on both exports in the Azure portal. This cannot be done via Terraform, and it must happen before the second apply. Instruct the user to:

1. Go to the Azure portal → Cost Management → Exports
2. For each export (actual and amortized):
   • Click the export name
   • Enable “File Partitioning”
   • Save
3. Run both exports manually once and wait for them to complete

Second Apply - Datadog CCM Config (Section 5)

After file partitioning is enabled and both exports have run once successfully, add Section 5:

1. Write datadog-ccm-config.tf with Section 5 (or restore it if it was moved out).

2. Save the plan, show it to the user, and apply that file only after explicit approval. The plan should contain only the new datadog_azure_uc_config resource, since the infrastructure already exists in state - applying the saved file is what guarantees the user gets the plan they approved:

   bashCopy

   for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
   DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
   # Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
   : "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   umask 077
   terraform plan -out=ccm.tfplan \
     || { echo "terraform plan FAILED - do NOT apply"; exit 1; }

   After the user approves the plan, apply it in a separate command:

   bashCopy

   for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
   DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
   # Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
   : "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   trap 'rm -f ccm.tfplan' EXIT HUP INT TERM
   terraform apply ccm.tfplan \
     || { echo "terraform apply FAILED - do NOT verify or report success"; exit 1; }

If datadog_azure_uc_config errors out on the second apply, the most common causes are:

• File partitioning wasn’t enabled on one or both exports
• Exports haven’t run yet (or haven’t completed)
• The role assignments from Section 4 haven’t propagated yet (can take a few minutes)

Phase 4: Verify Setup

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
resp=$(printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" \
  | curl -sS -w '\n%{http_code}' -X GET -H @- "https://api.${DD_SITE}/api/v2/cost/azure_uc_config")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "lookup failed with HTTP $code - do not assume 'not registered':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body" | jq . 2>/dev/null || printf '%s\n' "$body"

Apply the same shape check as in Phase 1 (stop on a missing or non-array data or configs). Find the nested configs[] records whose account_id, client_id and scope match the selected tenant, client and scope (on the existing-config path from Phase 1, the scope and exports of the config the user confirmed), and confirm both an actual and an amortized record exist with the expected export_name and storage_account. Then check each record’s status and error_messages:

• active with no error messages on both - setup succeeded. Cost data may still take time to appear; say so rather than claiming costs are already flowing.
• warn or error, or any error_messages - show the user the messages. Do not report success or send the completion callback; help them fix the cause (see the common causes above) and verify again.
• disabled, a missing record, or mismatched scope or export identities - setup is not complete. Tell the user and do not send the callback.

Wrap Up

After verification, make one best-effort completion callback so the Datadog UI can finish this flow.

DD_WORKFLOW_ID is the UUID of the Datadog user the credentials belong to, which is how the UI correlates this callback. Resolve it and post in one command: many agent runtimes start a fresh shell per command, so a variable assigned in an earlier one would be empty here.

Never print the current_user response: it also carries the user’s name, handle, and email. If no JSON parser is available, skip this callback rather than installing one or blocking setup.

for f in .env.local .env; do [ -f "$f" ] || continue; for k in DD_SITE DD_API_KEY DD_APP_KEY; do eval "[ -n \"\${$k:-}\" ]" && continue; v=$(grep -E "^$k=" "$f" | head -1 | cut -d= -f2- | tr -d '\r' | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
DD_SITE='datadoghq.com'; export DD_SITE   # <- replace with the site confirmed in Phase 0.
# Explicit assignment, not ':=': a wrong non-empty DD_SITE in .env would otherwise survive.
: "${DD_API_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
dd_headers() { printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY"; }
DD_WORKFLOW_ID="$(dd_headers | curl -H @- -fsS --connect-timeout 5 --max-time 20 \
  "https://api.${DD_SITE}/api/v2/current_user" | jq -er '.data.id')" \
  && dd_headers | curl -H @- -sS --connect-timeout 5 --max-time 20 -X POST \
  "https://api.${DD_SITE}/api/unstable/integration/azure/workflow/agentic_ccm" \
  -H "Content-Type: application/vnd.api+json" \
  -d '{"data":{"type":"integration_setup_status","id":"'"${DD_WORKFLOW_ID}"'","attributes":{"status":"finished","step":"setup_complete"}}}'

Do not retry or block setup if this callback fails.

Finish with a short summary for the user: the Azure tenant and cost scope now feeding Cloud Cost Management, the storage account and container in use (created or reused), the actual and amortized export names (created or reused), and whether resource collection was enabled in Phase 1 or was already on.

Let the user know:

• Cost data typically takes 24-48 hours to appear after the first export runs.
• Azure runs exports daily - the first data may arrive within a few hours.

Provide links:

• Cloud Cost Management: <APP_BASE>/cost
• Cost Analytics: <APP_BASE>/cost/analytics

Important Notes

• Azure cost exports can only be created by users with Billing Account or Subscription-level permissions.
• File partitioning must be enabled manually in the Azure portal - Terraform does not support this.
• The lifecycle { ignore_changes = all } block prevents Terraform from overriding manual Azure portal changes.
• The azuread provider is required for the service principal data source.
• Never run terraform apply without showing the plan to the user first.
