Problem Statement
What is GitHub Actions Marketplace?
Explanation
GitHub Actions Marketplace is a central hub for discovering and sharing reusable actions. Actions are pre-built steps that can be included in workflows, eliminating need to write common tasks from scratch. Marketplace contains thousands of actions for tasks like checking out code, setting up programming languages, deploying to cloud providers, sending notifications, and more.
Actions are referenced using uses keyword with owner/repo@version syntax: uses: actions/checkout@v3 uses checkout action from GitHub's actions organization at version 3. Marketplace actions are categorized (CI, deployment, code quality, security) and searchable. Popular actions include actions/checkout (checkout repository), actions/setup-node (setup Node.js), docker/build-push-action (build Docker images), and aws-actions/configure-aws-credentials (AWS authentication).
Using marketplace actions:
```yaml
steps:
- uses: actions/checkout@v3
- uses: actions/setup-node@v3
with:
node-version: '18'
- uses: docker/build-push-action@v4
with:
push: true
tags: myapp:latest
```
Marketplace accelerates workflow development by providing tested, maintained actions. You can also publish your own actions to marketplace. Understanding marketplace enables leveraging community contributions and avoiding reinventing common tasks.
