jk Jenkins CLI

Use jk to inspect and operate Jenkins Pipelines from the terminal.

Core Model

jk is Pipeline-native:

• Jenkins URLs are the primary identity. Use the exact URL the user would paste into a browser.
• Credentials are selected by normalized Jenkins host.
• Output is stable and self-owned. Prefer -o json for agent parsing, YAML for humans, and -o raw only when a command is explicitly raw/log-oriented.
• The tool is Pipeline-focused. Do not expect plugin, agent, credential-store, Freestyle, or Jenkinsfile-editing administration commands.
• It can inspect pipelines, trigger builds, watch builds, read logs, inspect stages, inspect submitted parameters, and respond to pending Pipeline input steps.
