SUMMARY

Two changes to the awx-operator job, both about disk headroom and about being able to diagnose it when it runs out.

1. Reclaim runner disk before the image build.

The job builds the AWX and operator images, loads a second copy of each into the kind node (containerd keeps its own), then pulls awx-ee, postgres, redis and ingress-nginx on top. Instrumenting the job puts the peak at roughly 10G, almost all of it under /var/lib/docker, and about 7G of that in a single docker volume — the kind node's /var.

The runner image itself already occupies ~60G before any of that, so the existing Free disk space after Docker build step has almost nothing to prune. It logs Total reclaimed space: 0B in every run I checked, including recent green ones on this repo.

This removes the preinstalled toolchains the job never uses, before the build. Measured sizes on the ubuntu-latest image: Android SDK 11.6G, dotnet 5.7G, ghcup 3.7G, swift 3.4G, CodeQL 1.7G — around 20G reclaimed. /opt/hostedtoolcache is deliberately left alone because setup-python installs into it.

2. Collect the debug bundle on any failure, not only on a timeout.

A run that dies because the filesystem filled up is not a timeout, so steps.awx_operator_test.outputs.timed_out is never set and nothing is uploaded — the job just stops mid-molecule with no artifact, which reads like a hang. This switches the condition to any non-success outcome and records df -h and docker system df -v into the bundle. It also frees space before writing, because at 0 bytes free kind export logs and kubectl describe fail silently, which is exactly the case the step exists for.

Summary by CodeRabbit

Chores

  • Improved build environment management to support more reliable image builds.
  • Enhanced diagnostics for failed operator tests, including filesystem and Docker usage details.
  • Added disk-space reclamation before diagnostic collection to help preserve failure evidence.
  • Failure logs and cluster diagnostics are now collected for operator test failures, regardless of timeout status.

📝 Walkthrough

Walkthrough

The CI workflow adds pre-build runner cleanup and expands operator failure diagnostics. It records filesystem and Docker usage after reclaiming space.

CI runner maintenance

Layer / File(s) Summary
Runner space cleanup
.github/workflows/ci.yml
The awx-operator job reports disk usage and removes selected preinstalled toolchains before image builds while retaining /opt/hostedtoolcache.
Operator failure diagnostics
.github/workflows/ci.yml
Diagnostics run for any failed operator test. The workflow reclaims Docker and toolchain space before creating diagnostic files, then records filesystem and Docker usage.

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

Merge Risk: ⚪ Minimal · up to 7dfb1

The workflow reclaims runner space before diagnostics are written and expands failure-bundle collection. No current merge-blocking risk is identified.

Fixed CodeRabbit's finding — moved the disk-reclaim check ahead of mkdir $DEBUG_OUTPUT_DIR and the writes, so cleanup runs before anything is created rather than after. Same reorder applied to the two sibling PRs (ansible/tower#7964, #7965), which had copied the identical ordering bug from this one.

Branch protection rule check failed

The awx-operator job builds the AWX and operator images, loads a second
copy of each into the kind node, then pulls awx-ee, postgres, redis and
ingress-nginx on top - roughly 10G at peak, nearly all of it under
/var/lib/docker. The runner image itself already occupies about 60G
before any of that.

The existing 'Free disk space after Docker build' step prunes the builder
cache, but there is almost nothing there to reclaim: it logs
'Total reclaimed space: 0B' in the runs I checked. Remove the preinstalled
toolchains this job never uses instead, which frees around 20G.
/opt/hostedtoolcache is left in place because setup-python installs there.

Also collect the debug bundle on any failure rather than only on a
timeout, and record df and docker system df in it. A run that dies from a
full disk is not a timeout, so today it produces no artifact at all and
reads like a hang. Reclaim space before creating or writing anything,
since at 0 bytes free the mkdir and redirects would otherwise fail before
any cleanup ran.
