Would be interesting to compare that size with other “trendy” lang. (such as Go, Python for instance)

Hi. I choose the best available option when it comes to the image size for my tests. I was also trying base images with JRE.

Thanks for that info. I can help with the tests. You can let me know once you have release ready.

jlink is a nice tool indeed. There is something that is questioning me though. I could not help but notice the image tag is ‘jdk-21’.
In my exp using plain JRE instead of JDK is a huge improvement in terms of space by itself. Consulting Bellsoft’s page for containers confirms that theory, the JRE image is already 71mb (ref -> https://bell-sw.com/libericajdk-containers)…

If you’re looking for images from the upstream distroless project, you can use `gcr.io/distroless/java21-debian12`. These images are built on top of temurin images.

Alternatively, you can use distroless and build your own image on top with `gcr.io/distroless/java-base-debian12`.

I was using distroless images (with java 11 and jib) some time ago. But what is the current most popular distroless with Java 21?

At Adoptium we are always looking for ways to keep the Temurin Alpine containers as tight as possible, and it looks like there are a couple of packages we can remove from the current image to slim down a bit further. Details of the analysis are here https://github.com/adoptium/containers/issues/458

If you have any ideas or can help test the proposed changes let us know via that issue.
