Add Docker build

[pfxuan]

This PR reuses the existing ubuntu CI build logic to build local or remote docker images across different setup.

Nice!! Love the fact that there's variables to control the lib/ubuntu version. Thanks for the PR @pfxuan !

@pierotofy Thank you for your help and support. Looking forward to see the next move for ODM + OpenSplat.

I tried the ROCm dockerfile through podman and while seemingly creating the image successfully after setting up all the deps, it doesn't seem to compile the final binary.

The README doesn't really say anything after running the setup of how to run through Docker.

Is there anything special for that?

I think the Dockerfile.rocm file is missing the build commands (everything else should be there though).

vs.

@pfxuan might have more insights.

Good catch. Dockerfile.rocm includes the full version of ROCm/HIP build environment but is missing the actual compile and build part. It should be very similar to this step. I'll probably add it from the next PR with an extra ROCm 6.0.2 support:
