CI/CD for Go Microservices on Scaleway Kubernetes with CircleCI

Microservices are essential for modern, scalable applications, and Scaleway's managed Kubernetes service, Kubernetes Kapsule, provides a powerful platform for running these containerized workloads in the cloud. This tutorial guides users through building a minimal Go microservice that offers a feedback API, containerizing it with Docker, and deploying it to Scaleway Kubernetes Kapsule using Helm and CircleCI, creating a GitOps-friendly workflow for continuous delivery. Users will learn to set up a Go module, define a data structure, implement an API handler, and test the application locally using Go's testing tools. The microservice is packaged as a Docker container and pushed to Docker Hub, then deployed to a Scaleway Kubernetes cluster using a custom Helm chart. The tutorial further includes configuring a CI/CD pipeline with CircleCI, which automates testing, building, and deployment processes, ensuring that only verified changes are deployed to the Kubernetes cluster. By the end, users will have a robust and automated development workflow, enhancing confidence in the reliability and scalability of their application deployments.
