Make pull-images respect the deployment flavor

[jakduch]

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

📝 Walkthrough

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.

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 Review

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.

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.
