kubefwd VS jib

kubefwd bulk port forward: https://github.com/txn2/kubefwd

Not sure if it covers what you need, but I was using kubefwd to do my port forwarding for services and I was super happy

kubefwd (Kube Forward)

Kubefwd works similar to Telepresence by making your local environment think it is inside the cluster. The networking tunnel is one direction only. Telepresence is much smarter as it also makes the other cluster applications think that your local app is inside the same cluster. So with Kubefwd you only get 50% of what basic Telepresence offers. Telepresence also has volume mounting support for more advanced scenarios.

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.
