Datadog OCI Integration

You are helping a user set up the Datadog OCI integration using Terraform.

The integration uses the official Datadog OCI Terraform module to create the required IAM resources (user, group, policies, API key) in the customer's OCI tenancy and register it with Datadog.

This is a hands-on setup: run the commands yourself as part of the conversation rather than handing the user a list, keep them in the loop, and pause for confirmation before terraform apply.

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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -n "$v" ] && export "$k=$v"; done; done
: "${DD_SITE:=datadoghq.com}"
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/

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 oci CLI is optional (it validates config and looks up OCIDs):

command -v terraform || echo "MISSING terraform - https://developer.hashicorp.com/terraform/install"
command -v oci >/dev/null 2>&1 && echo "oci: available" || echo "oci: not installed"

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: Verify OCI Credentials

Terraform's oci provider reads from ~/.oci/config, so that file must exist and be complete before terraform apply can succeed.

Settle the profile before running anything else in this skill. If the user named a profile, export it now; every snippet below, every oci CLI call, and the module's config_file_profile all read the same value. Skip this and the checks validate DEFAULT, which can be a different tenancy and user than the one being installed - the checks then pass or fail on the wrong identity:

export OCI_CLI_PROFILE="TEAM"   # <- the profile the user named; omit only if they said DEFAULT

Then check the required fields without dumping the file - an OCI profile can contain a pass_phrase, and printing the whole profile would put it in the transcript:

cfg="$HOME/.oci/config"
[ -r "$cfg" ] || { echo "missing or unreadable: $cfg"; exit 1; }
prof="${OCI_CLI_PROFILE:-DEFAULT}"
field() { awk -v p="[$prof]" -v k="$1" '/^\[/{inp=($0==p); next} inp && $0 ~ "^[ \t]*"k"[ \t]*=" {sub(/^[^=]*=[ \t]*/,""); gsub(/[ \t]+$/,""); print; exit}' "$cfg"; }
bad=0
for k in user tenancy region key_file fingerprint; do
  v=$(field "$k")
  [ -n "$v" ] || bad=1
  case "$k" in
    fingerprint) printf '%-12s %s\n' "$k" "$([ -n "$v" ] && echo present || echo MISSING)" ;;
    *)           printf '%-12s %s\n' "$k" "${v:-MISSING}" ;;
  esac
done
[ -n "$(field pass_phrase)" ] && echo "note: this profile has a pass_phrase; it is deliberately not printed"
keyf=$(field key_file); case "$keyf" in "~/"*) keyf="$HOME/${keyf#\~/}" ;; esac
if [ -n "$keyf" ] && [ -r "$keyf" ]; then echo "key_file     readable"
else echo "key_file     NOT readable: ${keyf:-<unset>}"; bad=1; fi
[ "$bad" -eq 0 ] || { echo "profile [$prof] in $cfg is incomplete - fix it before continuing"; exit 1; }

Every one of user, tenancy, fingerprint, key_file, region must be present, and the private key must be readable. An empty value or MISSING means the profile is incomplete - do not continue.

If the file is missing or incomplete, walk the user through setup:

1. Log into the OCI Console and navigate to Profile → My profile → API keys → Add API key.
2. Select Generate API key pair, download the private key, and save it to ~/.oci/oci_api_key.pem.
3. Set permissions on the key: chmod 600 ~/.oci/oci_api_key.pem
4. Copy the configuration file snippet that OCI displays after adding the key.
5. Save it to ~/.oci/config and ensure key_file points to the downloaded private key path.

If the oci CLI is available, the user can also run oci setup config --profile "${OCI_CLI_PROFILE:-DEFAULT}" to generate the config interactively as an alternative to the manual steps above.

Validate that the credentials actually authenticate:

If the oci CLI is available:

oci --profile "${OCI_CLI_PROFILE:-DEFAULT}" iam region-subscription list 2>&1

If this succeeds, proceed. If it fails with an authentication error, help the user fix the config before continuing.

Otherwise, skip the explicit validation here. terraform plan in Phase 3 will surface any auth issues with a clear error from the OCI provider - fix the config at that point if it fails.

Phase 2: Gather Information

The module needs the tenancy OCID and the OCID of the authenticated user. Both are already in the profile verified in Phase 1, which is the authoritative source - read them from there:

cfg="$HOME/.oci/config"; prof="${OCI_CLI_PROFILE:-DEFAULT}"
field() { awk -v p="[$prof]" -v k="$1" '/^\[/{inp=($0==p); next} inp && $0 ~ "^[ \t]*"k"[ \t]*=" {sub(/^[^=]*=[ \t]*/,""); gsub(/[ \t]+$/,""); print; exit}' "$cfg"; }
tenancy=$(field tenancy); user=$(field user)
case "$tenancy" in ocid1.tenancy.*) echo "TENANCY_OCID=$tenancy" ;;
  *) echo "tenancy in $cfg is missing or not an ocid1.tenancy OCID - fix Phase 1 first"; exit 1 ;; esac
case "$user" in ocid1.user.*) echo "USER_OCID=$user" ;;
  *) echo "user in $cfg is missing or not an ocid1.user OCID - fix Phase 1 first"; exit 1 ;; esac

Do not try to derive these from oci iam region-subscription list or oci iam user list: a RegionSubscription carries no tenancy id, and user list returns an arbitrary first user in the tenancy rather than the authenticated one, so both quietly produce the wrong value.

Confirm the two OCIDs with the user before continuing. If they want a different tenancy or user than the profile's, have them say so explicitly, or find the values in the OCI Console:

• Tenancy OCID: Administration → Tenancy Details.
• User OCID: Profile → My profile → the OCID is shown under the user's name.

The home region is read from the same profile, so it needs no separate input.

Also ask if they want to enable log collection (default: yes). Unlike the AWS, Azure, and GCP integrations, OCI log forwarding is part of this same module - logs_enabled = true provisions it.

Phase 3: Generate and Apply Terraform

Check what already exists - local Terraform first, then Datadog

Do this before generating or applying anything, and in this order. Local state first, because it decides whether an existing integration is something you can update or something you must not touch:

find . -maxdepth 1 -type f \( -name '*.tf' -o -name 'terraform.tfstate' \) -print
# A project is "present" if it has configuration - .terraform/ may simply not exist yet on a fresh clone
# with a remote backend, and terraform.tfstate does not exist at all when state is remote.
if [ -n "$(find . -maxdepth 1 -type f \( -name '*.tf' -o -name '*.tf.json' \) -print -quit)" ]; then
  terraform init -input=false >/dev/null || { echo "terraform init failed - resolve that before concluding anything about existing state"; exit 1; }
  out=$(terraform state list 2>&1); rc=$?
  if [ "$rc" -ne 0 ]; then
    case $out in
      *'No state file'*|*'no state'*|*'Backend initialization required'*)
        echo "project is initialized but has no state yet - treat as a clean install" ;;
      *)
        printf '%s\n' "$out"
        echo "could not read state (backend or credentials problem) - do NOT treat this as 'nothing exists'"; exit 1 ;;
    esac
  elif [ -z "$out" ]; then
    echo "state is empty - treat as a clean install"
  else
    printf '%s\n' "$out" | grep -F 'module.datadog_oci' || echo "state exists but holds no module.datadog_oci resource"
  fi
else
  echo "no Terraform configuration here yet - clean install"
fi

Match the exact resource address module.datadog_oci, not a loose grep -i datadog: unrelated Datadog resources, or cloud IAM left behind by a partial apply, would otherwise read as a managed integration.

Then ask Datadog what it already has:

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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -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.${DD_SITE}/api/v2/integration/oci/tenancies")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "lookup failed with HTTP $code - do not assume 'not connected':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body"

Now reconcile the two answers before doing anything:

• Not in Datadog, nothing in local state - a clean install. Continue.
• In Datadog and present in local state - this is the update/repair case, not a duplicate. Continue into the Terraform below as a change to the existing resources, and let the plan show what it will alter.
• In Datadog but absent from local state (the tenancy OCID from Phase 2 is already registered) - stop. Applying would either create a duplicate or fight with whatever manages it. Say so plainly and offer the options: manage it wherever it is already managed, or delete the integration in Datadog first. Do not offer terraform import here - this skill deploys a module, and a module has no single importable address, so there is no safe one-line import for it. Only continue if the user picks one and confirms.
• Present in local state but absent from Datadog - a partial or rolled-back install. The cloud-side resources may exist while the registration does not. Do not start from scratch: run the plan and let it show what is missing, and expect it to re-create only the registration.

Check for Existing Terraform

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

If existing .tf files are found, check for existing datadog or oci providers and reuse them.

Generate Terraform

The integration uses the official Datadog OCI Terraform module, pinned to a release tag. Terraform's lock file does not lock remote module revisions, so an unpinned Git source re-resolves the default branch on every fresh init - and this module creates IAM users, policies, API keys and Vault resources, so an upstream change would silently alter what an unchanged config provisions:

variable "datadog_api_key" {
  description = "Datadog API key"
  type        = string
  sensitive   = true
}

variable "datadog_app_key" {
  description = "Datadog application key"
  type        = string
  sensitive   = true
}

module "datadog_oci" {
  source = "github.com/DataDog/oracle-cloud-integration//datadog-terraform-onboarding?ref=datadog-integration-v1.1.17"

  datadog_api_key = var.datadog_api_key
  datadog_app_key = var.datadog_app_key
  datadog_site    = "<DD_SITE>"

  tenancy_ocid      = "<TENANCY_OCID>"
  current_user_ocid = "<USER_OCID>"

  # Must match the profile verified in Phase 1. The module builds its own providers and otherwise reads
  # DEFAULT, which can be a different identity than the one you just validated.
  config_file_profile = "<OCI_CLI_PROFILE>"

  logs_enabled = <LOGS_ENABLED>
}

The module handles all resource provisioning:

• Creates a Datadog service user and group in OCI
• Creates IAM policies granting Datadog read access to metrics, logs, and resources
• Generates an API key for authentication
• Registers the tenancy with Datadog via the API

Optional advanced variables (only include if the user needs them):

Apply Terraform

1. Replace all <PLACEHOLDER> values - <DD_SITE> from Phase 0, <TENANCY_OCID> and <USER_OCID> from Phase 2, <OCI_CLI_PROFILE> as the profile settled at the top of Phase 1, and <LOGS_ENABLED> as true or false.
2. Run terraform init to download the module.
3. Plan, and save the plan to a file. Both keys reach Terraform as TF_VAR_* environment variables, never as -var= arguments, which would put them in Terraform's command line:

   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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -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)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   export TF_VAR_datadog_api_key="$DD_API_KEY" TF_VAR_datadog_app_key="$DD_APP_KEY"
   umask 077          # tighten permissions on the plan file regardless
   terraform plan -out=tfplan
   

   
   Show the plan output to the user and wait for explicit confirmation.
4. Apply that saved plan, only after the user confirms it. Applying the file is what makes the approval meaningful: terraform apply with no plan file computes a brand-new plan, and -auto-approve would execute it without anyone seeing it, so anything changed since the plan would go in unreviewed:

   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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -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)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
   export TF_VAR_datadog_api_key="$DD_API_KEY" TF_VAR_datadog_app_key="$DD_APP_KEY"
   # EXIT cleans up; the signal handlers must also terminate, or a Ctrl-C would delete tfplan and
   # then fall through into a retry of a file that no longer exists.
   trap 'rm -f tfplan' EXIT
   trap 'rm -f tfplan; exit 130' HUP INT TERM
   attempt=1
   while :; do
     out=$(terraform apply tfplan 2>&1); rc=$?
     printf '%s\n' "$out"
     [ "$rc" -eq 0 ] && { echo "apply complete"; break; }
     case $out in
       *'no such host'*|*'dial tcp'*)
         if [ "$attempt" -ge 3 ]; then echo "still failing after $attempt attempts - stopping"; exit 1; fi
         echo "transient OCI endpoint lookup failure - retry $attempt of 3 in 10s"
         attempt=$((attempt + 1)); sleep 10 ;;
       *'stale'*|*'Saved plan is stale'*)
         echo "the saved plan is stale (state moved under it) - re-run the plan step and apply the NEW file"; exit 1 ;;
       *)
         echo "apply failed for a non-transient reason - do NOT retry and do NOT report success"; exit 1 ;;
     esac
   done
   

   
   The trap removes the plan file on every exit path, including Ctrl-C while the user is deciding. The if/else around the apply matters because a cleanup command as the block's last line would make a failed apply exit 0, and the agent would go on to "verify" a deployment that never happened. (It is an if rather than status=$? on purpose: status is a read-only variable in zsh.)
   OCI is the exception to how the other three skills handle keys. They pass nothing to Terraform at all - the Datadog provider reads the environment - so their plan files contain no secrets. This module takes datadog_api_key and datadog_app_key as ordinary module inputs, so both keys are recorded in the saved plan, and the API key additionally lands in state (the module provisions a Vault secret from it; the app key is only used for provider headers, which are not persisted), and neither can be ephemeral because the module feeds them to resources. Consequences to state out loud before planning: tfplan is a cleartext secret while it exists, umask 077 only limits other local users, and a remote state backend does not protect it. Add tfplan to .gitignore and never commit it. The traps above delete it on every exit path including Ctrl-C during approval - but if the agent's session is killed outright, delete it by hand.

Handling Transient OCI DNS Errors

OCI's identity endpoint intermittently fails with errors like: dial tcp: lookup identity.<region>.oci.oraclecloud.com: no such host

This is a known transient OCI issue - it does not mean the environment lacks OCI access. If terraform plan or terraform apply fails with this error, automatically retry the command up to 3 times with a 10-second pause between attempts. Do not tell the user their environment is misconfigured or that they lack OCI access based on this error alone.

Phase 4: Verify Setup

After terraform apply completes, verify the tenancy is registered:

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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -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.${DD_SITE}/api/v2/integration/oci/tenancies")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "lookup failed with HTTP $code - do not assume 'not connected':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body"

Confirm the response includes the tenancy OCID. Then check for metrics:

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=" "$f" | head -1 | cut -d= -f2- | sed 's/^["'\'']//;s/["'\'']$//'); [ -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)}"; : "${DD_APP_KEY:?not set - run dd-account-setup (commercial sites) or supply it directly (government sites)}"
sleep 10
resp=$(printf 'DD-API-KEY: %s\nDD-APPLICATION-KEY: %s\n' "$DD_API_KEY" "$DD_APP_KEY" \
  | curl -sS -w '\n%{http_code}' -G -H @- "https://api.${DD_SITE}/api/v1/query" \
  --data-urlencode "from=$(($(date +%s) - 900))" \
  --data-urlencode "to=$(date +%s)" \
  --data-urlencode "query=avg:oci.computeagent.cpu_utilization{*}")
code=$(printf '%s' "$resp" | tail -1); body=$(printf '%s' "$resp" | sed '$d')
[ "$code" = "200" ] || { echo "metric query failed with HTTP $code - that is NOT 'metrics still propagating':"; printf '%s\n' "$body"; exit 1; }
printf '%s\n' "$body"

If metrics are flowing, congratulate the user. If not, let them know OCI metrics typically appear within 5-10 minutes.

Important Notes

• The user must have IAM permissions to create users, groups, policies, and API keys in their OCI tenancy. For an identity-domain tenancy that means administrator rights on the target domain, since the module creates the service user and group there.
• The module requires Terraform >= 1.5.0 (its providers.tf declares required_version = ">= 1.5.0"). An older CLI fails during terraform init, so check terraform version before Phase 3. Every OpenTofu release satisfies this constraint - its versions start at 1.6 - so tofu version needs no separate check.
• existing_user_id and existing_group_id are an inseparable pair. The module has a precondition that fails when exactly one is set: pass both to reuse an existing user and group, or neither to have it create them.
• Only parent tenancies can be integrated - child tenancies inherit from the parent.
• The Terraform module source is github.com/DataDog/oracle-cloud-integration - this is the official Datadog module.
• For Terraform-managed integrations, deletion must be done via terraform destroy, not the Datadog UI.
• This module puts secret material in Terraform state. It creates an OCI API key for the Datadog service user and passes the Datadog API key into the resources it provisions, and sensitive = true redacts values from CLI output without removing them from state (HashiCorp docs). The module offers no way around this: its only credential inputs are the raw datadog_api_key and datadog_app_key variables - there is no input that accepts a pre-existing Vault secret OCID - and it provisions the Vault, Key, and Secret itself. So there are exactly two honest options, and the user must pick one before you plan: (a) accept it - and then configure the encrypted remote backend first, because Terraform's default is a plaintext terraform.tfstate in the working directory and moving state afterwards leaves the plaintext copy behind - or (b) stop here and use the OCI integration tile in the Datadog UI instead, which never puts the key in state at all. Do not imply a third option, and do not start a plan under option (a) until the backend is in place and verified.
• The Datadog API and app keys reach Terraform through TF_VAR_* at plan/apply time. Don't write them into a committed .tfvars file or any other persistent file. Note the module still places the API key in the plan and the state - see the state disclosure below; that is why the backend decision comes first.
• Never run terraform apply without showing the plan to the user first.
