This guide provides a step-by-step tutorial on using GitHub Actions with Kubernetes to deploy containerized applications. The workflow automates building, testing, and deployment of an app to a Kubernetes cluster using a custom Helm chart. GitHub Actions simplifies the Kubernetes deployment process by leveraging prebuilt Marketplace components for building Docker images and pushing them to a registry. The workflow also utilizes Helm to install the application in the Kubernetes cluster. To test the deployment, the app is accessed through Kubectl's port-forwarding feature. The guide covers key benefits of using GitHub Actions for Kubernetes deployments, including centralized management, automation, and CI/CD integration. It also highlights the importance of security, secrets management, scalability, and parallelization in Kubernetes deployments. Additionally, the guide mentions that while GitHub Actions is a compelling option for deploying apps, specialist CI/CD platforms like Spacelift can be a better fit for managing infrastructure.
