IRIS is a powerful platform and one of the new features is the Java Business Host (DOC: Connecting Systems Using Java Business Hosts) that allow you to develop Business Services and Business Operations directly in Java (JavaDocs of the InterSystems Gateway Package).
I was testing this feature using an IRIS Docker image, but this image doesn't come with Java, the image is a bare Ubuntu image plus IRIS. So I had to build a new image adding the Java stuff. After some research I finally get this Dockerfile:
I also build a docker compose file in order to create the container and start it in a easy way:
Everything works well after a 'docker-compose up -d'
Maybe this is useful for someone working with IRIS Docker images and Java Business Hosts.
