artifacts VS jib

One of the most interesting/unique features is the integration with OCI-compatible container registries. Tart can pull/push virtual machines from/to a registry. This feature was inspired by OCI Artifacts initiative.

JIB

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

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.

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:

We are ready to deploy now. First, we need to build and push the images to the registry. We can use the handy Jib commands provided by JHipster. Navigate to each of the microservice folders and run the commands below.

That Dockerfile's isn't that complicated. What is even easier is using Jib: https://github.com/GoogleContainerTools/jib
