Phaino

Run prowjobs on your local workstation with phaino.

Plato believed that ideas and forms are the ultimate truth, whereas we only see the imperfect physical appearances of those idea.

He linkens this in his Allegory of the Cave to someone living in a cave who can only see the shadows projected on the wall from objects passing in front of a fire.

Phaino is act of making those imperfect shadows appear.

Phaino shares a prefix with Pharos, meaning lighthouse and in particular the ancient one in Alexandria.

Usage

Usage:

# Use a job from deck
bazel run //prow/cmd/phaino -- $URL # or /path/to/prowjob.yaml
# Use mkpj to create the job
bazel run //prow/cmd/mkpj -- --config-path=/your/config --job=foo > /tmp/foo
bazel run //prow/cmd/phaino -- /tmp/foo

Phaino is an interactive utility; it will prompt you for a local copy of any secrets or volumes that the Prow Job may require.

Common options

• --grace=5m controls how long to wait for interrupted jobs before terminating.
• --print the command that runs each job without running it
• --privileged jobs are allowed to run instead of rejected
• --timeout=10m controls how long to allow jobs to run before interrupting them

See bazel run //prow/cmd/phaino -- --help for full option list.

Usage examples

URL example

• Go to your deck deployment
• Pick a job and click the rerun icon on the left
• Copy the URL (something like https://prow.k8s.io/rerun?prowjob=d08f1ca5-5d63-11e9-ab62-0a580a6c1281)
• Paste it as a phaino arg
  • bazel run //prow/cmd/phaino -- https://prow.k8s.io/rerun?prowjob=d08f1ca5-5d63-11e9-ab62-0a580a6c1281
  • Alternatively bazel run //prow/cmd/phaino -- <(curl $URL)

Configuration example:

• Use mkpj to create the job and pipe this to phaino
  • For prow.k8s.io jobs use //config:mkpj

    bazel run //config:mkpj -- --job=pull-test-infra-bazel > /tmp/foo
    bazel run //prow/cmd/phaino -- /tmp/foo
    

  • Other deployments will need to clone that rule and/or pass in extra flags:

    bazel run //prow/cmd/mkpj -- --config-path=/my/config.yaml --job=my-job
    bazel run //prow/cmd/phaino -- /tmp/foo
    

If you cannot use bazel (or do not want to), use go get -u k8s.io/test-infra/prow/cmd/phaino.
