gdal/docker - multi os/arch support, registry/image overrides

[awill1988]

Expected behavior and actual behavior.

1. I expected to be able to run docker pull osgeo/gdal:latest and run it in a raspberry pi. However, the only supported OS/ARCH is linux/amd64 as indicated on Docker Hub.

2. Additionally, looking at the shell scripts, you cannot provide your own registry/image location. This would be helpful for those seeking to independently build and host their own gdal container.

Steps to reproduce the problem.

1. Setup docker on a RPi, open a terminal and run docker run osgeo/gdal:latest
2. Attempt to run gdal/docker/alpine-small/build.sh to build and push, you will see that the BASE_IMAGE_NAME is not dynamic.

I think I'm going to close this as a wontfix. I don't have the build infrastructure to build for a Raspberry Pi. If you can provide modification to the Dockerfile itself as a pull request to be more configurable, please do it, but you'll have to Docker build it yourself.

Thanks @rouault for being proactive and prompt in handling of this. I probably should have mentioned or waited until my PR was ready, but I do intend to submit a request to update the build scripts that should satisfy all these features without breaking anything you guys the group is doing today. It will presume that the end-user will have docker buildx operational.

Just waiting for the water to boil (takes forever) and to make sure my changes successfully build the linux/arm64 os/arch before I commit and initiate the PR. Should I link this issue to it?

ok, great. re-opening this ticket until you sumit the PR
