Kubernetes Microservices on Azure with Cosmos DB

A temporary fix taken from the issue on GitHub is to override the health reporting implementation so that it returns DOWN instead of OUT_OF_SERVICE while the program is still starting. This blocks it from ever reporting OUT_OF_SERVICE. You can see the fix in the EurekaFix.java file in the store app.

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.
