Automated Worker Versioning with GitHub Actions

This post details the integration of Temporal's Worker Controller with GitHub Actions to automate the Worker Versioning process. It explains how to set up a CI/CD pipeline that triggers on code pushes, builds a Docker image for a new Worker Version, and applies a WorkerDeployment resource. The Worker Controller then manages the creation of versioned Kubernetes Deployments and Worker pods, enabling automated traffic ramping and graceful sunsetting of old worker versions. The post provides a practical example with a GitHub repository and a step-by-step guide to demonstrate the automated deployment in action.
