Version Numbers for Continuous Delivery with Maven and Docker

Version Numbers for Continuous Delivery with Maven and Docker

Dealing with version numbers is an important challenge on the way to Continuous Delivery. The classical versioning approach (“8.2.0”) and release workflow is inappropriate, because it can’t be automated properly. This post shows how we can leverage the Git commit hash to get rid of manual workflows and automate the Continuous Delivery pipeline. At the end, every build will produce an artifact which is potentially shippable. We’ll implement this solution with Maven and Docker.

Tutorial: Continuous Delivery with Docker and Jenkins

Introducing Continuous Delivery means to automate the delivery process and to release our application frequently. This way, we improve the reliability of the release process, reduce the risk and get feedback faster. However, setting up a Continuous Delivery pipeline can be difficult in the beginning. In this step by step tutorial I will show you how to configure a simple Continuous Delivery pipeline using Git, Docker, Maven and Jenkins.

Building a Dropwizard Microservice with Docker and Maven

Building a Dropwizard Microservice with Docker and Maven

Dropwizard produces a fat jar containing every dependency your microservice needs to run. This includes a web server. This way, no web server needs to be installed and configured on the target machine. However, there is some infrastructure left (like the JRE) which still has to be installed before the deployment. That’s where Docker enters the stage. With Docker we can produce an artifact containing really everything we need to run our microservice. In this post, we take a look at how we can integrate Docker into our Maven build, run our tests against the container and push the image to a repository.
