Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Preface

What Is CI/CD?

CI/CD is a method that helps application development teams to provide code changes to users more frequently and reliably. CI/CD introduces automation into the stages of code deployment.

When several developers collaborate and contribute to the same application (each of them responsible for a certain microservice or fixing a specific bug), they use a code version control provider to aggregate the application using the latest code versions that the developers have uploaded and pushed. GitHub, Bitbucket, and Assembla are examples of version control systems. The developers and testers push the application code and Docker files to automation software to build, test, and deploy the CI/CD pipeline. Jenkins, Circle CI, and GitLab CI/CD are examples of such automation platforms.

After passing the testing, a Docker image is built and published to your repository. These repositories can be either Docker Hub, your company's Docker Trusted Register (DTR), or Amazon Elastic...
