Deployment of CoMPAS

We deploy the (native) Docker image of all CoMPAS services to Docker Hub. This way, it can be pulled and deployed into environments of your choice (OpenShift for example).

Quick Deployment instructions (under construction)

The following instructions are terminal instructions for publishing a Quarkus docker image to Docker Hub. This should be done by a GitHub Action in the future.

docker login # Creating a Docker session

In order to publish it to Docker Hub, you have to login first and create a session.

./gradlew clean build -Pnative -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true -Dquarkus.container-image.group=group -Dquarkus.container-image.name=name -Dquarkus.container-image.push=true

Few points in this single command:

  • -Pnative creates a native executable (this needs some prework, see the Building Native Image documentation).
  • -Dquarkus.native.container-build=true creates a Linux executable without GraalVM being installed (only necessary if GraalVM is not installed).
  • -Dquarkus.container-image.build=true creates a container image with the native executable in it.
  • -Dquarkus.container-image.group=group defining the group name. Standard it's the system user name.
  • -Dquarkus.container-image.name=name defining the name of the image. Standard it's 'app'.
  • -Dquarkus.container-image.push=true deploys to docker image to Docker Hub.
