kubernetes was manually updated to 4437.v3a_18554d3f32 via the Jenkins
UI (the pin still said 4353.vb_47977da_9417) — this combination,
paired with kubernetes-client-api:7.3.1-256.v788a_0b_787114, is what
got a real build through checkout successfully. Pinning it here so a
future restart/reprovision reinstalls the version that's actually
been proven to work, not the untested original pin.
The kubernetes plugin fix worked — agent connected, checkout
succeeded, pipeline ran through 3 stages. Next failure:
loadConfig.groovy calls readYaml (to parse config.yaml), but that
step isn't in the chart's default plugin list at all, so it was never
installed: "No such DSL method 'readYaml' found among steps [...]".
Adds pipeline-utility-steps, which provides readYaml/writeYaml/
readJSON etc.
kubernetes:4353.vb_47977da_9417 requires kubernetes-client-api >=
7.3.1-256.v788a_0b_787114 (confirmed via plugins.jenkins.io), but that
plugin was never explicitly pinned in installPlugins — left to
resolve on its own at image-build time, it landed on an older,
incompatible version. Every build agent launch then crashed with
NoSuchMethodError: ConfigBuilder.withMasterUrl(String) inside
Reaper.preLaunch -> KubernetesCloud.connect ->
KubernetesFactoryAdapter.createClient: pods provisioned fine at the
Kubernetes API level, but the controller could never actually connect
an agent to them, so every demo-go-app build hung forever at "Still
waiting to schedule task".
