#  docker tag {repo}:{ver} ghcr.io/refresh-bio/{repo}:{ver}
#  docker push ghcr.io/refresh-bio/{repo}:{ver}
# May require:
#  docker login ghcr.io -u USERNAME
# To use docker image in registry but from singularity:
# singularity run docker://ghcr.io/refresh-bio/{repo}:{ver} splash input.txt
# conver to sif: singularity build {repo}_{ver}.sif docker-archive://{repo}_{ver}.tar


# Ok, after I created and pushed this on amd64 and arm64 linux I had two disjoint images on ghcr.io/refresh-bio/ (one was with correct tag, and the other was just digest (sha256)).
# I needed to grab both these sha's anr run docker manifest create ghcr.io/refresh-bio/splash:2.11.0     --amend ghcr.io/refresh-bio/splash@sha256:5f71c33a37ce54af4ca5fe4aaedb6ef28145e7cecfbdd4fb76d4d0f79d5f4f22     --amend ghcr.io/refresh-bio/splash@sha256:234738f09a459ec6658d3d3e3e6df67624a065bb50dd630d388d7fc9f7baeb3f
# then docker manifest push ghcr.io/refresh-bio/splash:2.11.0
# this added third package with tag 2.11.0 and the previous two are just visible as digest... anyway it seems it handles archs correctly
