Build Docker images for git tags (releases) on CI

[ferretdb-bot]

We already build Docker images on CI for PRs and pushes to main, but not for tags.

• On every new git tag, we should build a Docker image with tag matching git tag without leading v, and also tag it as latest. See Extract multiple Docker tags github-actions#130.
• We should support multiple names (ferretdb and ferretdb-dev).
• We should push that image to both https://github.com/FerretDB/FerretDB/pkgs/container/ferretdb and https://hub.docker.com/r/ferretdb/ferretdb.

See also #323.

Hi, i would like to work on this issue! I know just the basics , but i figured out this action might be useful. I might need help.

[ferretdb-bot]

There are two official actions from Docker:

• https://github.com/docker/metadata-action
• https://github.com/docker/build-push-action

Let's use them if possible, as I expect them to be better supported.

I could provide some help. I don't know much (yet ?) About golang. But I'm perfectly fine with ci stuff. Ping me if you struggle 🙂

@himanshu007-creator are you still working on it, or @Goopil could pick it up?

Sorry but I am stuck somewhere else, please @Goopil feel free to continue.

Hi guys,

just to be sure of what you need before starting

• Build multi arch x86, arm. Multi repo or prefixed ?
• each build should have all the label on the image (based on meta-action)
• the image build should include the build steps of the go or do you prefer a reuse of an already defined actions ?

I think it would be better to use a single existing repo with a version tag pointing to a manifest list with two manifests: one for amd64 and one for arm64. (I hope I got the terminology right).

We already have some steps defined in the Makefile that might be useful.

ok so something like this.

docker pull ghcr.io/ferretdb/ferretdb:x64-main
docker pull ghcr.io/ferretdb/ferretdb:arm64-main

docker pull ghcr.io/ferretdb/ferretdb:arm64-0.0.3
docker pull ghcr.io/ferretdb/ferretdb:arm64-latest

docker pull ghcr.io/ferretdb/ferretdb:x64-0.0.3
docker pull ghcr.io/ferretdb/ferretdb:x64-latest

yes thanks you i've seen it. And that help :) like i said i was not sur about the build part as you have no build logic inside of the dockerfile

[AlekSi]

docker pull ghcr.io/ferretdb/ferretdb:x64-main
docker pull ghcr.io/ferretdb/ferretdb:arm64-main

Can that be just docker pull ghcr.io/ferretdb/ferretdb:main, with the right architecture/manifest being selected automatically? I'm not an expert, but this blog post says that's possible.
