# gitlab-cicd-pipeline

A skill that steers your agent through writing .gitlab-ci.yml: stages, jobs, caching, artifacts, Kubernetes deploys. Useful when a pipeline needs building or reworking.

## What it does

The skill hands the agent a working shape for a GitLab CI/CD pipeline: stages from lint to production, dependency caching keyed on the branch, artifacts for test reports, conditional runs with `only` and `except`, and job ordering through `needs:`. It ships a minimal `.gitlab-ci.yml` example plus a `references/` folder covering full pipeline configuration, GitLab Runner setup, Docker layer caching, multi-project pipelines, and Kubernetes deployment.

There is also a do-and-don't list. The agent will push back on running tests serially when they can be parallel, suggest `expire_in` to stop artifacts piling up, and flag secrets sitting in config files. A security scanning stage is part of the set.

The skill does not register runners or wire up registry credentials for you, and that is outside its scope. If no GitLab Runner is available to the repository, the pipeline never starts — check that first.

## Requirements
- Works with: GitLab, Docker

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill gitlab-cicd-pipeline -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gitlab-cicd-pipeline/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gitlab-cicd-pipeline/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill gitlab-cicd-pipeline -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/gitlab-cicd-pipeline/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill gitlab-cicd-pipeline -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/gitlab-cicd-pipeline/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts gitlab-cicd-pipeline
```

2. **Manually: put the files in place**
- File: `.github/skills/gitlab-cicd-pipeline/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill gitlab-cicd-pipeline -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/gitlab-cicd-pipeline
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/gitlab-cicd-pipeline/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill gitlab-cicd-pipeline -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/gitlab-cicd-pipeline/SKILL.md

## When to use it
- write a `.gitlab-ci.yml` with build, test and deploy stages
- cache dependencies per branch so jobs stop refetching packages
- move test reports into artifacts with a bounded lifetime
- chain jobs with `needs:` to cut idle waiting
- add a security scanning stage to the pipeline

## Example prompts
- Write a `.gitlab-ci.yml` for a Node project with lint, test and build stages, caching `node_modules` per branch
- Split the test suite into parallel jobs and wire them with `needs:` so the pipeline finishes sooner
- Add a Kubernetes deploy stage and a review app for merge requests

## Table of Contents

- [Overview](#overview)

- [Quick Start](#quick-start)
- [Reference Guides](#reference-guides)
- [Best Practices](#best-practices)

## Overview

Create comprehensive GitLab CI/CD pipelines that automate building, testing, and deployment using GitLab Runner infrastructure and container execution.

## When to Use

- GitLab repository CI/CD setup
- Multi-stage build pipelines
- Docker registry integration
- Kubernetes deployment
- Review app deployment
- Cache optimization
- Dependency management

## Quick Start

Minimal working example:

```yaml
# .gitlab-ci.yml
image: node:18-alpine

variables:
  DOCKER_DRIVER: overlay2
  FF_USE_FASTZIP: "true"

stages:
  - lint
  - test
  - build
  - security
  - deploy-review
  - deploy-prod

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
    - node_modules/
    - .npm/

lint:
  stage: lint
  script:
    - npm install
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Use stages to organize pipeline flow
- Implement caching for dependencies
- Use artifacts for test reports
- Set appropriate cache keys
- Implement conditional execution with `only` and `except`
- Use `needs:` for job dependencies
- Clean up artifacts with `expire_in`
- Use Docker for consistent environments
- Implement security scanning stages
- Set resource limits for jobs
- Use merge request pipelines

### ❌ DON'T

- Run tests serially when parallelizable
- Cache everything unnecessarily
- Leave large artifacts indefinitely
- Store secrets in configuration files
