Is there a way to create multiple tags using the buildx build command in docker?-CodePudding

I am trying to use the docker buildx build command and I would like to be able to create multiple tags in one line. An example of what I have tried

docker buildx build . \
    --platform linux/arm64,linux/amd64 \
    --no-cache --push \
    -t test:latest -t test:${CI_COMMIT_SHORT_SHA}

I have seen this issue, but I haven't been able to get it to work https://github.com/docker/buildx/issues/396

CodePudding user response：

It works exactly as you've posted with multiple -t args, e.g. -t repo1:tag1 -t repo2:tag2:

$ regctl tag ls sudobmitch/demo
alpine
regcli-test
regctl
ubuntu

$ docker buildx build -f build/Dockerfile.regctl.buildkit -t sudobmitch/demo:regctl1 -t sudobmitch/demo:regctl2 --push .

This is assuming test was an example in your question. If you actually tried to push to the test repo, that expands to Docker Hub's Library, along side other official images like alpine, busybox, debian, etc. You don't have access to push there, so make sure to point to a repository where you have access to push images and have logged in.
