Note: This depends on the image nimmis/ubuntu being rebuilt with multiarch support This uses docker buildx and manifest lists to build a multiple versions of an image for different systems which appear as a single image on the docker hub. This allows clients to select the right version automatically. Changes: - Select the right cpu arch version when downloading java - Replace the java install in the Dockerfile with a call to set_java_ver - README updated on how to build these images
- libatomic1 is a depencency for Java on armv7 but not amd64. - Installing Java early while performing a multi-arch build results in Java for the host CPU being installed rather than the correct architecture

Note: This depends on the image nimmis/ubuntu being rebuilt with multiarch support. I've tested that it can build but not if it runs.

Possible problems:
I can't quite test this without your ubuntu image being multiarch but my fork which depends on debian allows the server to run on a 32 bit Raspberry Pi.
Java install in the docker file only is affected by the major version variable now. I don't know if the minor versions are necessary. Otherwise not installing java during the build also works as the client can download a copy.
The architecture aarch64 isn't tested as I don't have access to a machine to see the lscpu output. It seems like it should output "armv8".
