🔖 Feature description

Allow push to multiple container registries

🎤 Pitch

We want to maintain our images on multiple container registries so that if there is issue in one registry, we should be able to switch container registry and our deployments or applications aren't blocked

✌️ Solution

In case of normal docker build, it's easy We can write the script to change image tag and registry using docker tag in post-build and it works but in case of multi-arch or buildx post-build script doesn't work, can it be done from dev side? docker buildx -t registry1:tag -t registry2:tag --push and maybe add as many as we want Currently it takes only 1 selected registry to push the image
