The GCP counterpart of devops-lib. Registered in Jenkins under the same name, so consuming repos need no change: the two-line Jenkinsfile is identical on both clusters, and which library it resolves to is a property of the Jenkins running it. Substantive changes, all consequences of GKE being a real cloud: - Harbor speaks TLS here, so dind no longer passes --insecure-registry. It mounts the private CA at /etc/docker/certs.d/harbor.35.238.248.203.nip.io/ca.crt instead, from the registry-ca ConfigMap. This is not redundant with the node pool's trust: that covers pulls, performed by containerd on the node, while the push comes from dockerd in the build pod with its own trust store. Without it, pushes fail TLS verification while pulls of the same image succeed — which reads like a broken registry rather than a missing trust anchor. - The registry hostname changes in the push target and all five fallback Dockerfiles. It still must be spelled identically everywhere, because Docker matches credentials and trust by exact hostname. - helm_repo_url moves to cluster DNS. That clone runs in a build pod, so sending it out through the ingress and back would make the pipeline depend on Contour for pod-to-pod traffic. syncArgoApp already addressed ArgoCD this way and needed no change. - build-tools.Dockerfile is removed: devops-base-images-gcp owns it now, next to the mirrored base images, and the pod references the result by tag at base-images/build-tools:1. The base-images project is public, so the pod can pull it before it has any credentials. Verified: no homelab addresses remain; the pod template parses with the CA mount, the new image and no insecure-registry flag; and every fallback template's base image, with the default version buildDocker would pick, is present in the mirror manifest — an unmirrored tag now fails the build rather than silently falling back to Docker Hub.

# Fallback only — used when the repo has no Dockerfile of its own (see
|
|
# buildDocker.groovy). Simplified from the real go-Dockerfile: no SSH-keyed
|
|
# private module auth (github.com/Homelab/*), no per-module builds, no
|
|
# kafka-specific CGO toggle. Assumes a standard single-binary repo layout
|
|
# (main package at the repo root) — a repo with a different structure
|
|
# should just bring its own Dockerfile, same as demo-go-app does.
|
|
# Both stages pulled from Harbor's base-images project (mirrored from
|
|
# Docker Hub via devops-base-images), not Docker Hub directly — see that
|
|
# repo's README for the one-off mirror setup and why (build-time
|
|
# dependency on an external registry, plus wanting to pick the leanest
|
|
# variant of each deliberately rather than accept whatever a public tag
|
|
# defaults to). Only versions actually mirrored there resolve — passing
|
|
# a dockerBuildVersion whose tag isn't in devops-base-images/images.txt
|
|
# yet needs that added and re-mirrored first, unlike pulling straight
|
|
# from Docker Hub where any tag "just worked".
