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

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

| macOS/Linux | brew install avivsinai/tap/jk

| Windows | scoop bucket add avivsinai https://github.com/avivsinai/scoop-bucket && scoop install jk

| Go | go install github.com/avivsinai/jenkins-cli/cmd/jk@latest

| Binary | Download from GitHub Releases

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.
