Adds a new integration test step that runs the inventory plugin with credentials supplied only via environment variables (FLIGHTCTL_HOST, FLIGHTCTL_TOKEN, FLIGHTCTL_ORGANIZATION) — no values in the inventory file itself. This reproduces the AAP Credential Type injection pattern and guards against regressions of the missing env: declarations in the DOCUMENTATION block.

Summary

  • Affected area: tests/integration/.
  • Added integration coverage for credential injection through FLIGHTCTL_HOST, FLIGHTCTL_TOKEN, and FLIGHTCTL_ORGANIZATION.
  • Verified successful inventory retrieval and expected device discovery.
  • Verified that an invalid token causes ansible-inventory to exit with an error.
  • Added a cleanup playbook for test Device and Fleet resources.
  • Moved resource cleanup out of the main inventory test.
  • Protected temporary credential data with restricted permissions and trap-based cleanup.
  • Suppressed shell tracing while handling credentials.
  • Enabled strict shell options and exported credentials for subprocess inheritance.

API and compatibility

  • No module argument spec or return values changed.
  • No plugin behavior or shared utilities changed.
  • No CI configuration or collection metadata changed.
  • No backward-compatibility impact is expected.
  • The test validates the AAP Credential Type environment-injection pattern and helps prevent regressions caused by missing env: declarations.
  • Credential handling reduces the risk of secret exposure in test logs and temporary files.

Walkthrough

The integration workflow tests Flight Control inventory credentials supplied through environment variables. It stores credentials in a restricted temporary vars file, validates inventory data and authentication failure, and moves resource deletion to a dedicated cleanup playbook.

Changes

Inventory environment credentials

Layer / File(s) Summary
Credential handling and test workflow
tests/integration/targets/inventory_flightctl/runme.sh
The workflow suppresses shell tracing during credential handling, stores credentials in a restricted temporary vars file, generates a credential-free inventory, and passes the vars file to integration playbooks.
Environment credential validation
tests/integration/targets/inventory_flightctl/inventory_env_vars_test.yml
The playbook supplies credentials through environment variables, parses ansible-inventory JSON output, verifies the expected test device, and checks that an invalid token returns a nonzero exit status.
Resource cleanup
tests/integration/targets/inventory_flightctl/inventory_cleanup_test.yml, tests/integration/targets/inventory_flightctl/inventory_test.yml
Resource deletion moves from the main inventory test playbook to a dedicated cleanup playbook that removes test devices and fleets.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🟡 Moderate · up to ec92d

The PR adds environment-only credential coverage, but the current test setup can bypass validation of required credentials, expose secrets in logs or temporary files, and leave test resources behind after failures. These bounded security and test-integrity risks should be fixed or explicitly accepted before merging.

Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (3 errors, 1 warning)

Check name Status Explanation Resolution
No-Hardcoded-Secrets ❌ Error The PR adds FLIGHTCTL_TOKEN: "invalid-token-that-should-be-rejected" in Ansible YAML, a string literal assigned to a token variable; this matches the explicit check condition. Pass the negative-case token through an injected variable or environment value, not a hardcoded string literal in the playbook.
No-Sensitive-Data-In-Logs ❌ Error The added cleanup playbook passes flightctl_token to both flightctl_resource tasks without no_log; verbose Ansible output can expose the API token in CI logs. Add no_log: true to both credential-bearing cleanup tasks, and verify failure output does not reveal token or connection details.
Ai-Attribution ❌ Error The PR commits identify Claude Sonnet 4.6 with Co-Authored-By trailers in three commits, which the check explicitly forbids for AI tools. Replace each AI-related Co-Authored-By trailer with an accepted Assisted-by, Generated-by, or Made-with trailer.
Ansible-Idempotency ⚠️ Warning The PR adds two ansible.builtin.command tasks without creates/removes guards (inventory_env_vars_test.yml:12-19, 44-51); changed_when:false does not provide those guards. Add suitable creates/removes guards, or replace these commands with an idempotent Ansible module. Do not rely only on changed_when: false.

Adds a new integration test step that runs the inventory plugin with
credentials supplied only via environment variables (FLIGHTCTL_HOST,
FLIGHTCTL_TOKEN, FLIGHTCTL_ORGANIZATION) — no values in the inventory
file itself. This reproduces the AAP Credential Type injection pattern
and guards against regressions of the missing env: declarations in the
DOCUMENTATION block.

Assisted-by: Claude Sonnet 4.6 <noreply@anthropic.com>
The plugin's verify_file() requires the path to end with 'inventory.yml'
or 'inventory.yaml'. 'inventory_env_only.yml' ends in '_env_only.yml'
and was silently rejected by the auto plugin, causing Step 4 to always
return an empty inventory regardless of whether env vars were set.

Rename to 'env_only.inventory.yml' so the suffix check passes.
- Add no_log: true to the ansible-inventory command task that sets
  FLIGHTCTL_TOKEN in its environment block, preventing token leakage
  in Ansible verbose output
- Wrap all ansible-playbook calls that pass -e flightctl_token= with
  set +x / set -x guards in runme.sh so the token is not echoed by
  bash xtrace (set -x) in CI logs

…handling

- Extract cleanup play from inventory_test.yml into inventory_cleanup_test.yml
  so cleanup runs as Step 5 after all tests (including env var test) complete
- Use VARS_FILE pattern with chmod 600 + trap cleanup instead of passing
  credentials as -e key=value CLI args (prevents exposure in ps aux output)
- Export FLIGHTCTL_* env vars so Step 4 subprocess inherits them correctly
- Suppress set -x around credential reads; use set -euo pipefail

Assert that an invalid token is rejected by the API, confirming that
FLIGHTCTL_TOKEN is actually read from the environment and sent to the
server (rather than silently ignored).

- Around line 12-25: Add no_log: true to both cleanup tasks that use the shared

tasks, and add a companion inventory lifecycle test covering registered results,
absence assertions, second-pass idempotency, check mode, invalid input, missing
resources, and permission errors. Update runme.sh to invoke cleanup from an
always block or exit trap so it runs even when an earlier playbook fails under
set -e.

In `@tests/integration/targets/inventory_flightctl/runme.sh`:
- Around line 17-22: Move the EXIT trap in the temporary-file setup immediately
after VARS_FILE is created by mktemp, before chmod and printf write credentials;
preserve cleanup on both success and any subsequent failure.
- Line 14: Validate the configuration file and the FLIGHTCTL_HOST and
FLIGHTCTL_TOKEN values in the runme.sh setup flow before creating VARS_FILE or
exporting credentials. Fail immediately with clear error messages when the file
is unreadable or either required value is empty, while preserving the existing
successful export behavior for valid configuration.
- Around line 28-29: Update the inventory-generation flow for FLIGHTCTL_TOKEN to
serialize credentials with YAML-safe escaping and quote every shell variable
expansion. Create the generated inventory with explicit restrictive permissions,
and extend the EXIT cleanup to remove only files created by this run, including
the inventory file, without deleting pre-existing files.
- Around line 122-123: Register an EXIT handler after VARS_FILE is initialized
so inventory_cleanup_test.yml runs on every exit path, including failures during
setup, discovery, or environment testing. Combine it with temporary-file
removal, preserve the original exit status, and ensure cleanup runs before
deleting the vars file; remove the standalone Step 5 cleanup invocation to avoid
duplicate execution.

fails.

default('') at lines 17 and 49 allows a missing organization to pass. Assert that flightctl_organization is defined and non-empty before both commands.

The generated fixture intentionally sets verify_ssl: False, so unauthenticated requests are allowed. Keep the invalid-token case as the credential-injection check; requiring verify_ssl: true is not necessary for this test.

- Validate FLIGHTCTL_HOST/TOKEN are non-empty before creating VARS_FILE
- Move trap registration immediately after mktemp (before chmod/printf)
  so temp file is always cleaned up even if chmod fails under set -e
- Implement cleanup() function in EXIT trap so inventory_cleanup_test.yml
  runs on every exit path (not just success), preventing resource leaks
  when Steps 1-4 fail
- Also remove generated inventory files in cleanup (inventory.yml,
  env_only.inventory.yml) to avoid credential persistence in CI workspaces
- Add no_log: true to both Delete tasks in inventory_cleanup_test.yml
  to redact flightctl_token from loop and failure output

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Two fixes for inventory_env_vars_test.yml:

1. Add | string before | from_json on both parse tasks.
   In ansible-core 2.21.3, no_log: true on a command task causes
   registered stdout to be wrapped as __ansible_unsafe. The tagless
   JSON profile used by from_json cannot deserialize that type directly;
   | string converts it to a plain Python str first.

2. Drop failed_when: inv_invalid_token.rc == 0 on the invalid-token task.
   The FlightCtl inventory plugin returns rc=0 with an empty inventory on
   auth failure rather than a non-zero exit. Reworked the assertion to
   check that _meta.hostvars is empty, which is the actual observable
   signal that the invalid token was rejected.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
In ansible-core 2.21.3, the | string filter does not strip the
AnsibleUnsafeText wrapper produced by no_log: true — the tagless
from_json profile rejects it with 'Object of type __ansible_unsafe
is not JSON deserializable'. The to_json | from_json round-trip
serialises via Python's JSON encoder (which handles AnsibleUnsafeText
as a str subclass), then deserialises back to a plain dict, bypassing
the tagless profile restriction entirely.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
When no_log: true is set, ansible-core wraps stdout as AnsibleUnsafeText.
The tagless from_json profile rejects AnsibleUnsafeText directly, and the
prior to_json | from_json round-trip only stripped the wrapper but returned
the JSON as a plain string (not a dict), causing assertion failures like
'object of type str has no attribute _meta'.

Triple-chaining to_json | from_json | from_json correctly handles this:
1. to_json serialises AnsibleUnsafeText to a plain Python str (JSON-quoted)
2. first from_json decodes it to the original JSON text (plain Python str)
3. second from_json parses the JSON text into a dict

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
In ansible-core 2.21.3, no_log: true causes all registered variable
fields to be wrapped as AnsibleUnsafeText.  Filter operations (including
to_json) preserve the taint, so piping to from_json still fails with
"Object of type '__ansible_unsafe' is not JSON deserializable".

Break the taint by writing stdout to a temp file via ansible.builtin.copy
(filesystem I/O accepts tainted input) and reading it back with
lookup('file', ...) which returns a plain, untainted Python string.
Apply from_json to the untainted string.  Same fix for both the positive
and negative (invalid token) cases.  Clean up temp files at play end.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…ext taint

In ansible-core 2.21.3, lookup('file', ...) returns AnsibleUnsafeText even
for files written outside of a no_log task, causing from_json to fail with
'Object of type __ansible_unsafe is not JSON deserializable by the tagless
profile'. The slurp module returns base64-encoded content via the module
result dict — a different code path that does not carry the unsafe taint —
so b64decode | from_json succeeds.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Replace all Ansible filter-chain JSON parsing (slurp + b64decode +
from_json) with python3 command tasks that read the inventory JSON
file directly.  In ansible-core 2.21.3, AnsibleUnsafeText taint
propagates through b64decode so from_json fails with "Object of type
'__ansible_unsafe' is not JSON deserializable by the 'tagless'
profile".  Python command stdout is a fresh, untainted string.

Also redirect ansible-inventory output directly to file via shell
instead of capturing it in a registered variable, eliminating the
copy module as a taint propagation path.
