Jenkins CLI (jk)

jk is a GitHub CLI–style interface for Jenkins controllers. It provides modern, scriptable workflows for developers and operators.

Dependency Check

Before executing any jk command, verify the CLI is installed:

jk --version

For jk job create, jk job config, jk job configure, and jk job scan, use jk 0.0.29 or newer.

If the command fails or jk is not found, install it using one of these methods:

Only proceed with jk commands after confirming installation succeeds.

Authentication

# Login with credentials
jk auth login https://jenkins.example.com --username alice --token <API_TOKEN>

# Login with custom context name
jk auth login https://jenkins.example.com --name prod --username alice --token <TOKEN>

# Login with TLS options
jk auth login https://jenkins.example.com --username alice --token <TOKEN> --insecure
jk auth login https://jenkins.example.com --username alice --token <TOKEN> --ca-file /path/to/ca.pem

# Check auth status (active context)
jk auth status

# Logout from a context
jk auth logout              # Logout from active context
jk auth logout prod         # Logout from specific context

Options for auth login:

• --name — Context name (defaults to hostname)
• --username — Jenkins username
• --token — API token
• --insecure — Skip TLS verification
• --proxy — Proxy URL
• --ca-file — Custom CA bundle
• --set-active — Set as active context (default: true)
• --allow-insecure-store — Allow encrypted file fallback

Contexts

Contexts store controller URLs and credentials for easy switching:

# List contexts (* = active)
jk context ls

# Switch active context
jk context use prod-jenkins

# Remove a context
jk context rm staging

Environment: JK_CONTEXT overrides active context.
