Push Docker images on a registry

Pre-requisites

  • git
  • bash
  • docker
  • docker-compose

Generate Eclipse Steady images

In order to generate the Docker images to upload to a local registry, you should generate Eclipse Steady's Java archives. This can be done following Build JAVA archives/Docker images tutorial. To briefly summarize you should build and run an image which will populate your local directories with the Eclipse Steady JARs and WARs. In the end of this preliminary step you should have your images locally, this can be tested with the command docker images | grep steady.

Push the images to a registry

A script was created to push the images to a local Docker registry running inside your organization. This script simply tags the images and pushes them towards the registry.

To use the script you will need:

  • a registry in your organization (e.g., goharbor/harbor)
  • a username
  • Eclipse Steady used version

Invoke the script with the following positional arguments.

docker login [registry]
bash push-images.sh -r [registry] -p [project] -v [steady-version]

Pulling the images from a repository

You can use Docker to pull your images from a registry.

docker pull [registry]/[project]/steady-rest-backend:[steady-version]

Get going:

  1. Deploy a Kubernetes cluster on the Internet with the images you just pushed
