ko VS jib

Apko leverages the APK package format from Alpine and draws inspiration from ko, a fast container image builder for Go applications.

- There're many resources available about containerizing an application, but I suggest you buildpacks or ko, which doesn't require writing a Dockerfile

ko

You don't need to write and manage Dockerfiles. Simply just use ko: https://github.com/google/ko (You also don't need Docker Engine)

Or don't write a Dockerfile at all, and use ko: https://github.com/google/ko

Here is link number 1 - Previous text "ko"

It depends on your use case, but have you ever tried google/ko?

If you're using Go, I recommend https://github.com/google/ko (shameless plug), or for Java, use Jib.

I would recommend Google Ko if you are packaging Go apps: https://github.com/google/ko

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.
