We have previously seen how to set up a GitHub to Jenkins pipeline with webhooks, this time we are going to continue on that lesson and learn how to configure Jenkins to build and push Docker images to DockerHub. We’ll also see how to create images for both arm64 as well as amd64 architectures machines. Keep on reading.

In a typical CI/CD pipeline, what happens is when you push your code to a code repository (remote) like GitHub/GitLab/BitBucket, an event is triggered by the git host provider. This trigger is known as WebHook. This webhook can be used by some third-party service to provide an array of integrations. Do you want to tweet on every git push? You can do that.

In this post, I talk about why TDD is important. Why it is essential part of build process. I also talk a little bit about test coverage and having more coverage is always better. I also provision a Travis CI pipeline to test same application in different environments.

One of the benefits of multi stage build is that you can improve on build time. Second benefit is that size of your final images can drastically reduced.
