# 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:

```bash
jk --version
```

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

| Platform | Command |
|----------|---------|
| 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](https://github.com/avivsinai/jenkins-cli/releases) |

**Only proceed with `jk` commands after confirming installation succeeds.**

## Authentication

```bash
# 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:

```bash
# 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.

## Job Discovery

```bash
# Search across folders
jk search --job-glob '*deploy*' --limit 10

# Search in specific folder
jk search --folder team/services --job-glob '*api*'

# Filter by run results
jk search --job-glob '*' --filter result=FAILURE --since 7d

# With parameter filters
jk search --job-glob '*/deploy-*' --filter param.ENV=production
```

## Job Operations

```bash
# List jobs in root
jk job ls

# List jobs in folder (positional or flag)
jk job ls team/app
jk job ls --folder team/app

# View job details
jk job view team/app/pipeline
```

## Run Management

### Listing Runs

```bash
# List recent runs
jk run ls team/app/pipeline

# Limit results
jk run ls team/app/pipeline --limit 50

# Filter runs
jk run ls team/app/pipeline --filter result=SUCCESS
jk run ls team/app/pipeline --filter result=FAILURE --since 7d

# Filter by parameters
jk run ls team/app/pipeline --filter param.ENV=staging

# Include queued builds
jk run ls team/app/pipeline --include-queued

# Group by parameter
jk run ls team/app/pipeline --group-by param.ENV --agg last

# With metadata for agents
jk run ls team/app/pipeline --json --with-meta

# Pagination
jk run ls team/app/pipeline --cursor <cursor-from-previous>
```

### Starting Runs

```bash
# Start a run
jk run start team/app/pipeline

# Start with parameters
jk run start team/app/pipeline -p BRANCH=main -p ENV=staging

# Start and follow logs
jk run start team/app/pipeline --follow

# Start, wait for completion (no log streaming)
jk run start team/app/pipeline --wait --timeout 10m

# Get only the result
jk run start team/app/pipeline --follow --result

# Fuzzy job matching
jk run start deploy --fuzzy
```

### Viewing Runs

```bash
# View run details
jk run view team/app/pipeline 128

# Get only result status
jk run view team/app/pipeline 128 --result

# Exit with build result code
jk run view team/app/pipeline 128 --exit-status

# Wait for completion
jk run view team/app/pipeline 128 --wait --timeout 5m

# Show summary
jk run view team/app/pipeline 128 --summary
```

### Other Run Commands

# Quiet mode (minimal output)
jk run start team/app --quiet
```

## Global Options

- `-c, --context <name>` — Use specific context
- `--json` — JSON output
- `--yaml` — YAML output
- `--format json|yaml` — Output format
- `--jq <expr>` — Filter JSON with jq expression
- `-t, --template <tmpl>` — Format with Go template
- `-q, --quiet` — Suppress non-essential output

## Environment Variables
