jib VS source-to-image

You need to build Docker images for each app. This is specific to the JHipster application used in this tutorial which uses Jib to build the images. Make sure you are logged into Docker using docker login. Navigate to each app folder (store, invoice, product) and run the following command:

JIB

It is pretty easy to do with https://github.com/GoogleContainerTools/jib.

Save yourself the dockerfile and use jib: https://github.com/GoogleContainerTools/jib/tree/master/jib-maven-plugin

I first learned about Distroless because it was the default option in Google's Jib. Jib is a Maven plugin to create Docker containers without dependency on Docker. Note that the default has changed now.

Optimize your Dockerfile by using a small base Java Image, use either Spring Boot's layers tools or Google Jib to build your docker file, and increase CPU/Memory requests and limits if you can.

In this section, we will setup the automated generation and deployment of a Docker container image. You will need a Docker Hub account and the Jib Gradle Plugin.

If you don't want to hack on your own scripts to package your app into a container, I can recommend the JIB maven plugin. A gradle version is also available.

You can try and use s2i (source to image) - https://github.com/openshift/source-to-image You deploy container to your cluster that produce another image

Surprised to see it supports source-to-image (S2I). If you're using S2I, you're likely using OpenShift where your development pipeline is figured out for you. You wouldn't be using Shipwright on that platform.

If that's not an option, I unfortunately don't know how to compile source code into an IMG file from github, but I have a feeling that there's quite a few people who are knowledgeable in these matters lurking around this subreddit. The only thing I found was this: https://github.com/openshift/source-to-image but I have no idea how or where exactly to execute the code outlined in the readme below. Looks promising though.

Source-To-Image (S2I) is a toolkit for building images directly from source code without Dockerfile. This tool works well for simple, expected scenarios and workflows but quickly becomes annoying and clumsy if you need little too much customization or if your project doesn't have the expected layout. You might consider using S2I if you are not very confident with Docker yet or if you build your images on OpenShift cluster, as builds with S2I are a built-in feature.
