docs(terraform): add Terraform provider documentation and quickstart guide - #66
Added a Terraform navigation section with links to the overview, quickstart, guides, and provider reference.
Added setup instructions for configuring API-key authentication, including environment variables, Terraform variables, and CI or HCP Terraform secrets.
Added a quickstart covering provider setup, compute instances, catalog data, and resource cleanup.
Added a guide to deploy and verify a web server on a cloud instance, with steps to remove the instance afterward.
Documented supported Terraform resources, data sources, and actions, along with links to their references.
No actionable comments were generated in the recent review.
Walkthrough
The documentation adds a Terraform navigation section, provider overview, API-key authentication guide, quickstart, web-server deployment walkthrough, and resource reference.
Changes: Terraform documentation
Layer / File(s)
Summary
Provider overview and reference terraform/overview.mdx, terraform/resources.mdx, docs.json
The overview describes provider configuration and defaults. The resource reference lists supported resources, data sources, and the reboot action. Navigation links to the Terraform pages.
Provider setup and authentication terraform/authentication.mdx, terraform/quickstart.mdx
The authentication guide documents API-key configuration through environment variables, sensitive variables, CI secrets, and HCP Terraform workspace settings. The quickstart covers provider setup, compute deployment and cleanup, and catalog data sources.
The docs are mostly sound, but several small inaccuracies remain that could confuse readers. A reader may run terraform destroy from inside an SSH session, or may expect the manually installed web server to be recreated by reapplying the files. Reboot is attributed to the wrong resource, and the quickstart SSH command lacks the port and user. The API key can also end up in shell history, and the api_key field is marked required. These are quick fixes and are worth addressing before merge.
Security architecture risk: Low · up to 7be06
The PR does not change the provider or deployed infrastructure, but its authentication examples can lead users to retain powerful API keys in unintended places. Exploitation requires adoption of the guidance and access to a credential-bearing artifact; no actual credential disclosure is demonstrated.
Retained concerns
Medium · security · inferred: The new guidance offers a sensitive, non-ephemeral input-variable route without explaining saved-plan credential retention, and presents hosted masking too broadly. Alongside the literal shell export example, this can extend bearer-key exposure from intended secret storage into artifacts with different readers and retention policies. This is an operational security concern introduced by the guidance, not a change to provider authentication enforcement.
Security review details
Security Blast Radius
inferred — An attacker must obtain a credential-bearing artifact, rather than merely read this public documentation. A stolen bearer key can exercise its creator's documented team-role authority; the evidence does not support global or arbitrary cross-tenant authority.
Security Findings and Attack Paths
inferred — The documented variable is sensitive but not ephemeral. The retained saved-plan finding establishes that input values can persist in cleartext saved plans; a reader of such an artifact could recover the key. This is conditional on supplying a real key through that route and producing an accessible saved plan, not proof that a key has already leaked.
inferred — Replacing the export placeholder with a real key in an interactive shell can retain that key in history when history is enabled. Recovery requires access to that history; the example contains no actual credential.
observed — The HCP instruction asserts masking in logs and state. The retained finding identifies best-effort redaction and possible environment-variable inclusion in trace logs, but explicitly does not establish that this specific key is logged. The supported concern is an overbroad confidentiality assurance, not demonstrated log disclosure.
Trust Boundaries and Controls
inferred — The relevant boundary separates intended credential storage and execution from artifacts available to other readers. Environment-variable preference, secret-store advice, sensitive marking, and rotation warnings are meaningful countercontrols, but do not establish that saved plans, shell history, and diagnostic logs share the secret store's access controls or retention policy.
Resilience and Maintainability Implications
observed — The guide requires rotation after exposure, and existing API documentation describes revocation and rejection of revoked keys. The available evidence does not establish cleanup ownership for interrupted Terraform runs, retained plan copies, or saved-plan behavior after revocation.
Hardening Proposals
proposed — Distinguish display masking from persistence guarantees. Document protected handling and retention of saved plans, history-safe local secret injection, diagnostic-log precautions, and rotation or revocation after suspected exposure. Keep provider-environment authentication as the preferred documented route without describing it as universally leak-proof.

Review comments at @terraform/authentication.mdx:
- Line 18: Replace the inline API key assignment in the shell setup instructions
with a silent interactive read before exporting STRETTCH_CLOUD_API_KEY, so users
do not enter the key as part of a command recorded in Bash history.
- Line 32: Update the authentication input-variable documentation around
sensitive = true to clarify that sensitivity does not hide values from saved
Terraform plans. Recommend supplying the API key through an environment variable
for automation and protecting saved plan files from unauthorized access.
- Line 55: Update the STRETTCH_CLOUD_API_KEY guidance to explain that marking
the workspace environment variable sensitive makes it write-only in the HCP
Terraform UI and Variables API, but does not guarantee log masking: redaction is
best-effort, and TF_LOG=TRACE may expose environment variables in logs.
Review comments at @terraform/guides/deploy-a-web-server.mdx:
- Around line 113-117: Update the “Tear it down” step to tell readers to exit
the interactive SSH session and return to the project directory before running
terraform destroy; preserve the existing destroy command.
- Line 130: Update the Verify text to avoid claiming the web server is defined
entirely in Terraform, and revise the reproduction description to clarify that
Terraform creates the compute instance while Nginx and the page must be
installed through the SSH steps for each new instance.
Review comments at @terraform/overview.mdx:
- Line 76: Remove the required badge from the api_key ResponseField in the
Terraform overview so it matches the provider’s environment-variable setup and
does not imply that users must configure an api_key argument.
- Line 44: Update the Compute instances description in the overview and the
matching description in the resource documentation to list create, update,
resize, and destroy as resource operations; document reboot separately as the
strettchcloud_compute_reboot action, noting its Terraform 1.14+ requirement.
Review comments at @terraform/quickstart.mdx:
- Line 82: Update the Terraform quickstart connection guidance after `terraform
apply` to specify SSH user `root` and port `222` when connecting to the
`public_ip` output. Match the deployment walkthrough’s connection settings
instead of implying the default SSH port.
Review comments at @terraform/resources.mdx:
- Line 42: Update the Terraform Registry documentation wording so it does not
imply the latest reference matches the installed provider version; direct
readers to select their installed provider version in the Registry instead.

When a user replaces the placeholder in an interactive Bash shell, Bash normally saves the literal command in its history. Anyone who can read that history can recover the API key. Use a silent read prompt before exporting the variable instead. (gnu.org)

Return to the local terminal before teardown.
Line 91 starts an interactive SSH session. The guide never ends that session before Line 117 runs terraform destroy. A reader who follows the steps in order runs the command on the instance, not in the initialized local Terraform directory, so teardown fails and the instance remains provisioned. Add an exit step before the destroy command and tell the reader to run it from the project directory. (developer.hashicorp.com)

A new instance will not have the page until the SSH setup steps are repeated. The Verify step also incorrectly says the web server is defined entirely in Terraform.

Document reboot as an action, not a compute resource operation.
strettchcloud_compute has no reboot argument. Reboot uses the separate strettchcloud_compute_reboot action and requires Terraform 1.14+. A reader following this resource description cannot configure a reboot through the resource. Correct this line and the matching description in terraform/resources.mdx Line 15.

Every argument is optional, and each can be set with the matching **`STRETTCH_CLOUD_*`** environment variable. In practice you only set `api_key` — and even that is read from the environment by default (see [Authentication](/terraform/authentication)).

Remove the required badge from api_key.
The required property marks this field as required, but the provider accepts STRETTCH_CLOUD_API_KEY instead of an api_key argument. The badge contradicts the setup instructions and can lead readers to put a key in configuration. Remove required from this field. (mintlify.com)

Specify the SSH user and port.
After terraform apply, a reader who connects with the default SSH port cannot reach the instance. The deployment walkthrough specifies user root and port 222. Give the quickstart reader the same connection command, for example ssh -p 222 root@"$(terraform output -raw public_ip)". (raw.githubusercontent.com)

Do not describe the latest reference as version-matched.
The link opens the latest published provider documentation. Terraform can install a version constrained by ~> 1.0 or retain an older version from .terraform.lock.hcl.
