# How Can I Contribute Without Coding: Self-Hosted Infrastructure and DevOps Automation

Welcome to this comprehensive guide on contributing to self-hosted infrastructure without the need for extensive coding skills. This article is designed for experienced sysadmins, DevOps engineers, and homelab enthusiasts who wish to automate their infrastructure using open-source tools.

Prerequisites

1. Operating System: Ubuntu 20.04 LTS (Focal Fossa)
2. Docker: apt install docker-ce=5.0.8 - Stable Docker version 5.0.8
3. Docker Compose: apt install docker-compose-plugin
4. Git: apt install git

Setting Up Your Homelab

1. Clone a Repository: Start by cloning a repository of your choice containing Docker Compose files, which define the services running in your homelab. For this example, we’ll use traefik-letsencrypt-example.

git clone https://github.com/traefik/examples.git
cd examples/acme/docker-compose

1. Configure Docker Compose Files: The docker-compose.yml file contains service definitions. Modify the configuration files to suit your needs, such as changing network settings or adding additional services.

2. Start the Services: With the configuration in place, you can now start your homelab using Docker Compose:

docker-compose up -d

Potential Security Considerations

1. Port Exposure: Ensure that only necessary ports are exposed to the outside world and that access is secured via a firewall or reverse proxy.
2. Service Credentials: Store sensitive information such as database passwords securely, using environment variables or secrets management solutions like Vault.
3. Update Regularly: Keep your services up-to-date to minimize vulnerabilities.

Troubleshooting

If you encounter issues during setup or operation of your homelab, consult the relevant documentation and online forums. Common pitfalls include misconfigured environment variables, incorrect service definitions in Docker Compose files, and connectivity problems with external resources (e.g., Let’s Encrypt).

Conclusion

By understanding and contributing to self-hosted infrastructure using open-source tools, you can improve your skillset and reduce dependency on third-party services. This guide provides a starting point for setting up a homelab with minimal coding requirements, allowing you to focus on configuration and automation aspects of DevOps.
