Docker Setup

Setting up woodpeckerci/woodpecker-server using Docker is straightforward and can be completed in a few steps. Below, we outline the process along with common tips to ensure smooth installation.

Prerequisites

• Ensure you have Docker installed on your machine.
• Familiarize yourself with basic Docker commands.

Step-by-Step Guide

1. Pull the Docker Image:

   docker pull woodpeckerci/woodpecker-server

2. Run the Docker Container: You can run the container with the following command:

   docker run -d --name woodpecker \
     -p 3000:3000 \
     -e木鸟CI__DB_TYPE=sqlite \
     -v /path/to/config:/config \
     -v /path/to/woodpecker-data:/data \
     woodpeckerci/woodpecker-server

   Explanation:

   • -d: Runs the container in detached mode.
   • --name woodpecker: Names the container for easier management.
   • -p 3000:3000: Maps port 3000 on your host to the container’s default port.
   • -e木鸟CI__DB_TYPE=sqlite: Sets environment variables. SQLite is used as the default database type.
   • -v /path/to/config:/config: Mounts a configuration directory from the host to the container.
   • -v /path/to/woodpecker-data:/data: Mounts a data storage directory for persistent data.

3. Accessing Woodpecker: Open your browser and navigate to http://localhost:3000 to access the web interface.

Common Issues & Tips

• Environment Variables: Ensure that all necessary environment variables are correctly set, especially those related to database configuration.
• Volume Mounts: Using volume mounts for data directories ensures that your configurations and data persist even if you stop or remove the container.
• Network Configuration: If you encounter network issues, check Docker’s network settings or use --network host to run the container directly on the host network.

By following these steps, you should have a functional instance of Woodpecker CI up and running in no time. Happy coding!

Security Essentials

When running woodpeckerci/woodpecker-server in Docker, it’s crucial to implement several security measures to ensure a safe and secure environment:

1. Use Official Images: Always pull the latest official image from Docker Hub to benefit from any security patches or updates.

2. Run as Non-Root User: To minimize potential damage if an attacker gains access, configure Woodpecker to run as a non-root user using the USER directive in your Dockerfile or by setting the WOODPECKER_RUN_USER environment variable.

3. Secure Configuration Files: Store sensitive information such as database passwords and API keys outside of the Docker container. Use environment variables or encrypted secrets managers like HashiCorp Vault for secure storage.

4. Limit Exposed Ports: Run Woodpecker with only necessary ports exposed. By default, it runs on port 3000. Ensure that this port is properly secured and firewalled to limit external access.

5. Update Regularly: Keep your Docker images up-to-date by regularly pulling the latest tags from the official repository to benefit from security updates.

6. Limit Privileges: When running in a container, limit privileges as much as possible. Use --cap-drop and other security options available in Docker to reduce potential damage if an attacker gains control of your container.

7. Use Secure Protocols: Ensure that all communication between components is secured using HTTPS. For development purposes, consider setting up a reverse proxy like NGINX with TLS certificates.

8. Regularly Audit Logs: Enable logging and regularly review logs for any suspicious activity or errors. Configure Woodpecker to log to stdout or a centralized logging solution for easier monitoring.

By following these guidelines, you can significantly enhance the security of your Woodpecker CI/CD environment when running it in Docker.
