Configuring Self-Hosted Runners with GitHub Actions
Introduction
In this post, co-authored with Veeraveni Ajay, I’ll provide an overview of configuring self-hosted runners with GitHub Actions. This is part of my exploration in software engineering, leveraging tools to streamline CI/CD processes and scale application deployments effectively.
Why Self-Hosted Runners?
We chose self-hosted runners to gain more control over our CI/CD environment, ensuring consistency with our production setup and improving cost efficiency for large-scale operations.
Tech Stack
To achieve this setup, we used:
- Amazon EKS (Elastic Kubernetes Service): To manage our Kubernetes environment.
- GitHub Actions: For defining and running CI/CD workflows.
- Docker: For containerizing our applications and runners.
- Terraform: For infrastructure as code, enabling us to provision and manage cloud resources efficiently.
Streamlining CI/CD
By leveraging these tools, we were able to:
- Improve Consistency: Ensure our CI/CD environment closely matched our production environment, reducing deployment issues.
- Enhance Scalability: Easily scale our runner capacity by adding nodes to our Kubernetes cluster.
- Increase Cost Efficiency: Reduce costs by using our own infrastructure instead of relying solely on GitHub-hosted runners.
Conclusion
Configuring self-hosted runners with GitHub Actions allowed us to streamline our CI/CD pipeline, making it more efficient and scalable. This setup is a testament to how we can use modern tools to optimize application deployments.
