CI/CD for Microservices on DigitalOcean Kubernetes

Semaphore and DigitalOcean's managed Kubernetes service can be combined to create an efficient CI/CD pipeline for deploying Docker containers. The process involves setting up a Ruby Sinatra microservice, packaging it in Docker, and deploying it to DigitalOcean Kubernetes, with Semaphore automating tasks such as dependency installation, unit testing, Docker image creation, and deployment. The article provides a detailed guide on connecting these services, including initial setup, creating secrets for authentication, configuring Semaphore for continuous integration, building Docker images, and deploying to Kubernetes. It also touches on advanced deployment strategies like canary and blue-green deployments, encouraging users to explore and customize their processes for enhanced software development productivity.
