Why are you introducing these changes? (Problem description, related links)

pull-images always fell back to the Katello flavor and could not be given a flavor explicitly. This made preloaded images differ from a later Satellite or proxy deployment.

Fixes #846

What are the changes introduced in this pull request?

• expose a persisted --flavor option for pull-images
• provide community and Satellite/Capsule flavor choices
• use the Satellite flavor directly in the Satellite CI job instead of adding foreman-proxy as a workaround
• document flavor selection and add parser regression coverage

How to test this pull request

• python -m pytest --confcutdir=tests/unit tests/unit/pull_images_test.py -v
• ruff check tests/unit/pull_images_test.py
• run ansible-lint on src/playbooks/pull-images

Checklist

• Tests added/updated
• Documentation updated

Rebase and CI follow-up (28 October)

Rebased the single commit onto current master, preserving the feature patch. The previous failures were Compliance UI 404 responses, Vagrant metadata HTTP 502 and an interrupted Galaxy download. The two previously failing Compliance pages both passed in the current IOP Smoker run, so this retry does not require another open PR to merge.

All 6 targeted pull-images parser tests, Ruff and targeted Ansible lint passed. git diff --check passed. Full deployment CI is being refreshed. No local VM or container stack was started; temporary reports and test files were removed.

Walkthrough

The pull-images playbook now declares flavor choices and includes vendor overrides. Unit tests cover built-in and Satellite flavor parsing, optional features, and persisted flavor state. Documentation describes flavor selection and its default. The Satellite test workflow passes the satellite flavor.

Changes: Pull-images flavor selection

Layer / File(s)	Summary
Define and test flavor choices src/playbooks/pull-images/metadata.obsah.yaml, vendor_overrides/satellite/pull-images/metadata.obsah.yaml, tests/unit/pull_images_test.py	The playbook metadata defines built-in flavor choices and includes vendor overrides. Satellite metadata adds satellite and capsule. Tests cover built-in and vendor flavors, the iop feature, and parsing a persisted flavor.
Document and use flavor selection docs/developer/deployment.md, .github/workflows/test.yml	The documentation describes explicit and persisted flavor selection and the katello default. The Satellite test workflow passes --flavor satellite for both air-gapped and non-air-gapped runs.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: evgeni

Merge Risk: Low · up to 37aa4

The example may fail in a community checkout. Clarify its prerequisite or use a community flavor; this does not otherwise prevent merging.

Security architecture risk: Low · up to 37aa4

The new choices are limited to named deployment flavors, and no introduced security issue was established. The persistence behavior behind conflicting or invalid saved values remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The affected execution scope is an operator-invoked image pull on the playbook's quadlet hosts. The changed parser helpers are confined to temporary test paths; they do not establish a new deployed entrypoint or network-facing caller.

Trust Boundaries and Controls

• observed — Command metadata constrains explicit flavor choices before the existing privileged playbook selects a variables file. The tests establish acceptance of named choices and reading one stored value, but do not establish validation or precedence for conflicting or invalid stored values.

Resilience and Maintainability Implications

• observed — The persistence test seeds an isolated temporary state file and checks a parser result. It does not exercise persistence writes, interruption, repetition, concurrent use of one state path, or recovery, so those transition guarantees remain unverified.

Hardening Proposals

• proposed — Verify that persisted flavor values are checked against the installed choices, that explicit-versus-stored precedence is defined, and that persistence failures cannot leave an unintended flavor for a later privileged pull.

Explanation

Issue #846 requires explicit or persisted flavor selection, a Katello default, and image selection that follows the flavor and enabled features. The change adds pull-images --flavor metadata, includes vendor flavor overrides for satellite and capsule, preserves the playbook Katello default, and reuses _flavor_features. Tests cover built-in flavors, vendor flavors, persisted flavor, and satellite with iop. The Satellite CI job now selects --flavor satellite instead of adding foreman-proxy as a workaround. Documentation describes the new behavior.

The failing Tests Proxy Deployment (default, none, centos/stream10) job is unrelated to this change. The setup step failed while installing community.general from Ansible Galaxy with Connection reset by peer; the subsequent missing theforeman.forklift.sos_report error is a consequence of that incomplete dependency installation. I will retry the failed jobs once this workflow run finishes.

[jakduch]

The remaining core matrix failure is unrelated to this PR. I checked the uploaded SOS report for job 107867567827: at 23:19:04 the kernel OOM killer selected the Candlepin Java process, and candlepin.service exited with status 137 after a 1.3 GiB memory peak. Candlepin had been healthy earlier in the same run; its disappearance caused the later Katello API and service-test failures.

This PR only changes pull-images metadata/tests and the Satellite workflow, not the failing core/IOP matrix. I tracked the CI resource issue separately in #864.

[jakduch]

I checked the CentOS Stream 9 IOP SOS report as well. It has the same independent failure: at 19:20:29 the kernel OOM killer selected Candlepin Java PID 66182, and the service exited 137. I updated #864 with evidence from both CentOS 9 and 10 jobs.

[jakduch]

The separate CI memory problem now has a proposed fix in #865, which lowers the Candlepin heap only for development tuning and leaves production profiles unchanged.

[pablomh]

Would this pull the IOP images in the case of the satellite flavor? If so, I'd love to see this in, because we've seen several instances of the iop feature deployment because the iop images were pulled at deployment time and sometimes failed.

[jakduch]

Yes, with one distinction: iop is an optional feature, not part of the Satellite flavor itself. If it was enabled by an earlier deployment, pull-images reuses the persisted feature set and pulls the IOP images. Before the first deployment, the explicit command is foremanctl pull-images --flavor satellite --add-feature iop.

I added this exact combination to the parser tests and documented it.

The failing deployment jobs hit the Candlepin heap/OOM problem fixed on current master by #865. I rebased this branch onto that fix; CI is running again.

[jakduch]

The only remaining exact-head failure is the CentOS Stream 10 fapolicyd content-proxy job. It is the shared 3 GB proxy-memory failure now fixed by PR #884; the same matrix job is green in its exact-head run. This branch's pull-images changes are not on the failing path. I will rebase it after PR #884 lands.

[jakduch]

Rebased onto the current master. The only new failure was an unrelated runner shutdown during the database migration step, not a failure of the flavor-aware image pull change. The content is unchanged in de55c62; the guarded force-push restarted the full workflow.

[ehelms]

I prefer not to call out a specific flavor here other than for the initial sentence where it serves as instructional.

[ehelms]

We should not need to repeat the vendor_overrides, and rather make the existing ones re-usable.

[ehelms]

Does these tests match flavor tests present in deploy or deploy-proxy ?

[jakduch]

Rebased onto current master. The new migration job stopped while downloading containers.podman from Ansible Galaxy with SSL: UNEXPECTED_EOF_WHILE_READING, before deployment tests ran. I restarted the full workflow via guarded force-push in dfc398c; no code change was needed for that download failure.

[jakduch]

Rebased onto current master in d1d7b0f, keeping one commit and the same feature patch. The previous Compliance UI 404 is no longer blocking: both affected menu-page tests passed in the current IOP Smoker run. The other failures were test-environment setup/download errors. All six targeted parser tests, Ruff and targeted Ansible lint passed. Fresh CI has been started.
