Sc 30273 aws automation for terraform #32
Conversation
- Introduced .gitignore to exclude Terraform and IDE-related files. - Added data.tf for JIT API authentication to retrieve access tokens. - Configured REST API provider in providers.tf for global headers and authentication. - Updated README.md to advise on moving the restapi provider for better module management when commenting out.
- Included a reminder in both `terraform.tfvars` files for organization and single account examples to never commit sensitive values to the repository and to supply them in a secured way. - This change enhances security awareness for users configuring JIT API credentials.
WalkthroughReorganized Terraform authentication: moved JIT auth HTTP data source to data.tf and REST API provider to providers.tf, removing them from main.tf. Added guidance in README, security comments in example tfvars, and a .gitignore for Terraform/IDE/OS artifacts. Changes

3-4: Ensure HTTPS and normalized base URL to avoid double slashes.If local.jit_api_endpoint may end with a trailing slash, you’ll end up with “//authentication/login”. Most servers handle it, but best to normalize the local to not end with “/”.
Would you like me to add a local that trims any trailing slash, e.g.,
replace(var.jit_api_endpoint, "/+$", ""), and re-use it across files?

❓ Verification inconclusive
Access token and response body will be stored in Terraform state (secrets exposure).
data.http.jit_auth.response_body will be persisted to state, leaking the access token to any state backend. This is a significant secret-management risk.
Consider one of these safer patterns:
- Supply the bearer token to Terraform via a sensitive input variable (populated by CI or a pre-apply script) so it never lands in state as a computed value.
- If the restapi provider supports a built-in OAuth2/bearer_token mechanism or environment variable, use that instead of injecting the header from a data source.
- If automation of login must remain in TF, move the token fetch outside Terraform (pre-step) and pass via TF_VAR_jit_access_token or provider-specific env var.
Additionally, you can harden the postcondition to ensure the token is present in the successful response:
lifecycle {
postcondition {
- condition = self.status_code == 200
- error_message = "JIT authentication failed with status ${self.status_code}"
+ condition = self.status_code == 200 && can(jsondecode(self.response_body).accessToken)
+ error_message = "JIT authentication failed, status ${self.status_code} or accessToken missing"
}
}Two follow-ups:
- Confirm your backend state location is encrypted and access-controlled (e.g., S3 with SSE + restricted IAM, TFC/TFE, etc.).
- If you want, I can propose an end-to-end change to swap to a sensitive input variable for the token and a small helper script to export TF_VAR_jit_access_token.
Critical: Access token is persisted in Terraform state (secrets exposure)
The data.http.jit_auth.response_body (and thus the decoded accessToken) will be saved in your Terraform state, leaking credentials to anyone with access to that state.
Recommendations to remediate immediately:
- Don’t fetch the token inside Terraform. Instead, retrieve it beforehand (e.g., in CI or a wrapper script) and pass it in as a sensitive input variable (
TF_VAR_jit_access_tokenor provider-specific env var). - If your REST provider supports OAuth2 or a built-in bearer_token mechanism (via settings or env vars), use that rather than rolling your own HTTP call.
- If you must keep the HTTP call in Terraform, at minimum refactor so that only a boolean success flag is stored, never the full
response_body.
You can also tighten your postcondition to verify the token is present without storing it:
lifecycle {
postcondition {
- condition = self.status_code == 200
- error_message = "JIT authentication failed with status ${self.status_code}"
+ condition = self.status_code == 200 && can(jsondecode(self.response_body).accessToken)
+ error_message = "JIT authentication failed: status ${self.status_code} or accessToken missing"
}
}Next steps:
- Ensure your remote state backend is properly encrypted and access-controlled (e.g., S3 with SSE + least-privilege IAM, TFC/TFE).
- Refactor the token acquisition out of Terraform into a sensitive input. Happy to help draft a small helper script and TF changes if needed.

🧩 Analysis chain
Provider configuration cannot safely depend on a data source; this will likely fail plan.
provider "restapi" references data.http.jit_auth.response_body for Authorization. Provider configs are evaluated before data sources, so this dependency commonly breaks evaluation and plan. Even if it worked, it inherits the “token in state” problem.
Prefer injecting the token via a sensitive input variable (or provider-supported env var), and remove the data source reference from the provider block. For example:
headers = {
"Accept" = "application/json"
"Content-Type" = "application/json"
- "Authorization" = "Bearer ${jsondecode(data.http.jit_auth.response_body).accessToken}"
+ "Authorization" = "Bearer ${var.jit_access_token}"
}Then declare in variables.tf:
variable "jit_access_token" {
type = string
sensitive = true
description = "Bearer token for JIT API. Provide via TF_VAR_jit_access_token or workspace variables."
}Feed it from CI/CD or a pre-apply login step so it never appears as a computed value in state.
🌐 Web query:
In Terraform, can a provider configuration reference values from data sources? What are the constraints?
💡 Result:
A provider configuration in Terraform cannot reference values from data sources. This is a deliberate and fundamental constraint of Terraform's evaluation model.
Essential context and constraints:
- Provider configuration arguments—the values inside a
providerblock—can only use values that are known before the apply phase begins. This includes hard-coded values and input variables, but it explicitly excludes any data that comes from managed resources or data sources, since those are generally evaluated only after provider configuration is complete[4]. - The Terraform documentation states:
"You can use expressions in the values of these configuration arguments, but can only reference values that are known before the configuration is applied. This means you can safely reference input variables, but not attributes exported by resources (with an exception for resource arguments that are specified directly in the configuration)."
Why is this restriction in place?
- Provider configuration is evaluated as one of the very first steps when Terraform runs—even before data sources or resources are read or created. The provider needs to be fully configured before it can fetch information (or create resources) on behalf of Terraform[1][4].
- Data sources, on the other hand, are resolved only after the provider is configured and available for queries, and sometimes even after certain resources have been created or updated[7]. This creates a dependency cycle if a provider configuration tried to depend on a data source.
What can be used in provider blocks?
- Hard-coded literals (strings, numbers, etc.)
- Input variables (e.g.,
var.project_id) - Functions and static expressions that resolve before provider configuration
What cannot be used?
- Resource attributes (e.g.,
aws_vpc.main.id) - Data source attributes (e.g.,
data.aws_caller_identity.current.account_id) - Any value that is not fully determined at configuration-load time
| Configuration Argument | Can Reference Data Source? | Can Reference Input Variable? |
|---|---|---|
Provider block (e.g., aws) |
No | Yes |
| Resource or data block | Yes | Yes |
How to work around this limitation:
- If you need provider configuration (such as account ID or region) to be dynamically determined, you must arrange for inputs (variables) to have the value required—possibly by running external scripts or capturing outputs from previous runs, not by using Terraform data sources within the same configuration[4][1].
Reference locations:
- Direct quote from HashiCorp docs:
"You can use expressions in the values of these configuration arguments, but can only reference values that are known before the configuration is applied. This means you can safely reference input variables, but not attributes exported by resources (...)"[4].
Summary:
Provider blocks cannot use data sources in any form, as this would cause a circular dependency—providers must be configured before any data or resources are evaluated[4][1]. Use input variables for dynamic values needed by providers.

🌐 Web query:
Does the popular terraform-provider-restapi support configuring a bearer token via a dedicated argument or environment variable, instead of headers?
💡 Result:
Short answer: No — the common terraform-provider-restapi implementations do not expose a dedicated "bearer token" argument or a built‑in REST_API_BEARER (or similar) environment variable. Instead you either:
- Pass the Authorization: Bearer header via the provider's headers map (commonly by referencing a Terraform variable whose value you set from the environment), or
- Use the provider's oauth_client_credentials block so the provider obtains an OAuth token for you (client_id/secret + token endpoint).
Evidence:
- Provider docs list a headers map (used for Authorization) and an oauth_client_credentials block (client credentials flow). (github.com)
- The provider docs/implementations expose env vars for things like REST_API_USERNAME / REST_API_PASSWORD / REST_API_INSECURE, but there is no documented REST_API_BEARER / bearer_token env var. (pkg.go.dev, libraries.io)
- Examples show people supplying a bearer token via the headers map (often by reading a TF variable populated from the environment). (gist.github.com)
Suggested options
- If you already have a token: set it in a Terraform variable (for example via TF_VAR_my_token) and pass it into provider.headers:
- headers = { "Authorization" = "Bearer ${var.my_token}" } (this is the usual pattern). (gist.github.com)
- If you want the provider to fetch tokens for you: configure oauth_client_credentials with client id/secret/token endpoint. The provider will obtain and attach the token automatically. (github.com)
If you tell me which fork/version (Mastercard, Jimdo, bourbon, etc.) you’re using I can point to the exact docs or show a copy/paste example for that release.

Provider block cannot reference a data source for the Authorization header
Terraform evaluates provider configurations before data sources, so
data.http.jit_auth.response_body will break planning and incur a “token in state” issue.
Pinpointed location:
- src/integrations/aws_integration_automation/providers.tf, Line 10
Required change: replace the data source interpolation with a sensitive input variable.
headers = {
"Accept" = "application/json"
"Content-Type" = "application/json"
- "Authorization" = "Bearer ${jsondecode(data.http.jit_auth.response_body).accessToken}"
+ "Authorization" = "Bearer ${var.jit_access_token}"
}Then declare in variables.tf:
variable "jit_access_token" {
type = string
sensitive = true
description = "Bearer token for JIT API. Provide via TF_VAR_jit_access_token or workspace variables."
}Populate var.jit_access_token from your CI/CD or a pre-apply login step so the token is never computed by Terraform.
🤖 Prompt for AI Agents
In src/integrations/aws_integration_automation/providers.tf around line 10, the
provider block currently interpolates data.http.jit_auth.response_body for the
Authorization header which is invalid (providers are evaluated before data
sources) and leaks a token into state; replace that interpolation with a
reference to a new sensitive input variable (e.g., var.jit_access_token) and
update the provider to use that variable for the "Authorization" header. Also
add a variable declaration in
src/integrations/aws_integration_automation/variables.tf for jit_access_token
with type = string, sensitive = true and a short description, and ensure the
token is supplied from your CI/CD or via TF_VAR_jit_access_token or a pre-apply
login step so Terraform never computes or stores the token itself.

Clarify Terraform behavior: provider placement doesn’t prevent destroy when commenting out a module
This guidance is misleading. In Terraform, removing/commenting out a module from configuration causes Terraform to plan destroying its managed resources regardless of where the provider is defined. Moving the REST API provider “outside” will not prevent that. Recommend correcting the note to avoid accidental destroys.
Apply this diff to replace the note with accurate guidance:
-- If you intend to comment out the entire module - it's better to move the restapi provider outside - to allow commenting it out without performing `terraform destroy`.
+- If you need to temporarily exclude this module, do not comment it out and apply. Terraform will plan to destroy its managed resources regardless of where the REST API provider is defined. Instead, either:
+ - Keep the module in the configuration and use targeted applies (e.g., `terraform apply -target=<other_module_or_resource>`) to work on unrelated changes, or
+ - Place this integration in its own Terraform root/state so it can be left untouched while you modify other stacks.
+ To intentionally decommission the integration, run an explicit `terraform destroy` targeting this module.📝 Committable suggestion
