Build #7 failed with "Cannot connect to the Docker daemon at
tcp://localhost:2375" right at the first sh step. Verified the dind
entrypoint script directly (docker-library/docker's
dockerd-entrypoint.sh) — with DOCKER_TLS_CERTDIR="" and a
dash-prefixed arg it correctly builds
`dockerd --host=tcp://0.0.0.0:2375 --insecure-registry=...`, so the
--insecure-registry flag added last commit isn't logically wrong.
This is a container-start race instead: Kubernetes doesn't guarantee
ordering between containers in the same pod, so the docker-cli
container's first sh can fire before dockerd in the sibling container
has finished its startup checks (iptables detection etc. run on every
start). Polls `docker info` for up to 60s before the actual build
instead of assuming instant availability.
docker push was hanging: "Client.Timeout exceeded while awaiting
headers" doing a TLS handshake against harbor-core.harbor.svc.cluster.local,
which only ever speaks plain HTTP (TLS disabled cluster-wide by
design). Docker defaults to HTTPS for any bare registry hostname
regardless of network path — that default has nothing to do with
whether traffic routes through Contour/Ingress, contrary to what an
earlier pending-items note assumed. Adds --insecure-registry to the
dind container's dockerd startup args.
Build #5 got through checkout, loadConfig, and the pre_build hook,
then hit two real bugs at the actual docker build step:
1. `docker build` failed with "mkdir /root/.docker/buildx: read-only
file system" — dind-pod.yaml mounts the Harbor push-auth secret
read-only at /root/.docker, but modern docker defaults to
BuildKit/buildx, which wants to write its own state there. Forces
the classic builder via DOCKER_BUILDKIT=0 instead.
2. The subsequent error-handling itself then threw a
NullPointerException — every stage file (including untouched
legacy ones from the real devops-lib) reads env.FAILURE when
setting currentBuild.result, but nothing in this repo ever defined
it, so it was null. Defined once in homelabPipeline.groovy rather
than touching 40+ individual occurrences across every stage file.
Drops AGENTS.md, BUGS_AND_IMPROVEMENTS_REPORT.md, CLAUDE.md,
ai-blitz/*, and docs/{SECURITY.md,acronyms.md,adr/*} — leftover
documentation and task scaffolding from the original org-wide devops-
lib that don't describe this homelab's simplified single-service
pipeline. These were already missing from the working tree from
earlier cleanup; this commit just records that state.
