I have been using Maven for almost a year and have recently started using GitLab CICD. I am trying to develop CIs for the build and deployment of microservices. Each microservice is packed in a docker container and stored in Nexus. We will be using Kubernetes to manage the distribution of the services to test and production environments.

We are a small team of 3 developers and we currently have around 10 services. Both of these numbers will increase so it is important that we find a way to describe the workflow and to automate it as much as possible.

Reading around the subject, some have suggested that each build should be seen as a potential release. I understand this to mean that there should only be one build and this build gets retagged as it is promoted towards a release.

My difficulty here is regarding the use of SNAPSHOT and version numbers in the project POMs.

My current plan:

  • use feature-branches while implementing new features
  • when complete, features will be merged with the development branch which causes a full build and test.
  • the resulting docker image will be stored in Nexus as x.y.z-${COMMIT_ID}
  • a release-candidate will be merged to releases/x.y.z triggering a retag of the docker image in Nexus to x.y.z-rc
  • a release will be merged from releases/x.y.z to the master branch triggering a retag of the docker image in Nexus to x.y.z

(Deployment to actual servers will be handled by Kubernetes)

Do I need to use SNAPSHOT at all with this kind of workflow? The microservice projects don't have build-dependencies on each other so I can't immediately see the point of adding SNAPSHOT to the POM version numbers.

Can any one comment on this? Are there any well-documented workflows for this type of project?
