Plank

Plank is the controller that manages the job execution and lifecycle for jobs running in k8s.

Usage

$ bazel run //prow/cmd/prow-controller-manager -- --help

Configuration

GCS and S3 are supported as the job log storage.

# config.yaml

plank:
  # used to link to job results for decorated jobs (with pod utilities)
  job_url_prefix_config:
    '*': https://<domain>/view
  # used to link to job results for non decorated jobs (without pod utilities)
  job_url_template: 'https://<domain>/view/<bucket-name>/pr-logs/pull/{{.Spec.Refs.Repo}}/{{with index .Spec.Refs.Pulls 0}}{{.Number}}{{end}}/{{.Spec.Job}}/{{.Status.BuildID}}'
  report_template: '[Full PR test history](https://<domain>/pr-history?org={{.Spec.Refs.Org}}&repo={{.Spec.Refs.Repo}}&pr={{with index .Spec.Refs.Pulls 0}}{{.Number}}{{end}})'
  default_decoration_configs:
  # All entries that match a job are used, later entries override previous values.
  # Omission of 'repo' and 'cluster' fields makes this entry match all jobs.
