Part 3. Hands-on CI/CD pipelines

You’ve smashed through parts 1 and 2 but you’re still hungry for more. I understand. Thankfully, this part is designed to give you a lot to chew on.

You’ll implement CI/CD workflows for real-world, cloud-native applications. In the next few chapters, you’ll run automated tests with Docker, analyze your Docker images for security vulnerabilities, and deploy containerized microservices on Docker Swarm and Kubernetes. You’ll learn how to automate the deployment process for your serverless applications. This is just a tiny glimpse, so roll up your sleeves and let’s dive into this!
