Integrating GitHub Actions with Harness streamlines Continuous Integration and Continuous Delivery (CI/CD) processes, facilitating the building of Docker images and deploying Kubernetes applications. GitHub Actions automates development workflows through YAML-defined processes stored in the GitHub repository, which can be triggered by various events. These workflows can be used to create CI pipelines that build, test, and publish artifacts to platforms like Docker Hub. The blog details creating a CI workflow with GitHub Actions, including setting up a "build" and "create_dockerfile" job, triggered by code commits and requiring Docker credentials for artifact publishing. Harness is then utilized for deploying the Docker image to a Kubernetes environment, with a step-by-step guide for setting up and triggering deployments efficiently. The integration of these tools exemplifies a modern approach to managing software development workflows, enabling rapid deployment and continuous delivery in a Kubernetes setting.
