Migrate docker build from DockerHub to GitHub Container Registry

[eastata]

The issue is a part of global migration from DockerHub to GitHub Container Registry.

• Docker images for applications mpc, client, prover

  • builded by buildx for linux/amd64. List of platform can be extended for the future
  • building use contaner registry as a remote docker cache cache-mpc, cache-client, cache-prover
  • initial build generate docker images with tags based on git hash. Workflow is ready for extention by docker-compose for integral tests
  • Build triggered by release tag vX.Y.Z

• Base image still the same, only migrated to GitHub CR

  • Build triggered by release tag docker-base-vX.Y.Z

Docker images

Docker files	Image	Tags	Description
./Dockerfile-prover	ghcr.io/clearmatics/zeth:latest-prover	latest-prover, X.Y.Z-prover - Release of zeth, git-%HASH%-prover - developers build by git-commit	Zeth Prover Server. Image use zeth-base for building
./Dockerfile-client	ghcr.io/clearmatics/zeth:latest-client	latest-client, X.Y.Z-client - Release of zeth, git-%HASH%-client - developers build by git-commit	Python client to interact with the prover
./Dockerfile-mpc	ghcr.io/clearmatics/zeth:latest-mpc	latest-mpc, X.Y.Z-mpc - Release of zeth, git-%HASH%-mpc - developers build by git-commit	Tools for Multi-Party Computation. Image use zeth-base for building
./Dockerfile-base	ghcr.io/clearmatics/zeth:latest-base	latest-base, A.B.C-base - Release of zeth-base	Base image for building other containers

* Build triggered by release tag `vX.Y.Z`

@eastata - can we still manually push docker images to this registry? I'd like to push the "application images" for the 0.5 and 0.6 tags (which I guess, won't be re-built - or will they?)

Yes. You have to configure docker client using GITHUB_TOKEN

I see, thanks @eastata
