multiple export point

[kenotsolutions]

Hi,

Does buildkit support multiple output points something like below lines?
--output type=image,name=prod.docker.io/username/image,push=true
--output type=image,name=test.docker.io/username/image,push=true \

When I try to do add multiple outputs it gives the error.

error: currently only single Exports can be specified

Is there any other way to do that?

--output type=image,"
name=prod.docker.io/abc:3, name=test.docker.io/abc:3"

exports only prod.docker.io

Thanks

Multiple outputs are not allowed atm but for your case you can just specify multiple values for name, separated by a comma. Note that in cli you also need to quote the value because the format is csv. #807 (comment)

@tonistiigi could you provide an example for the quotes? Do I quote the whole value? Or every name value separately?

I dare say the correct format is:

--output type=image,\"name=reg1/img:1,reg2/img:2\",push=true

Note, that you have to place quotes around "name=..." and escape them \"name=...\". Then replace ellipsis with your comma separated reg/img:tag entries.

This works for GithubActions and worked for GitlabCI as well, as was described in the answer that helped me

Using --output type=image,\"name=$IMAGE:$TAG,$IMAGE:$CI_COMMIT_SHA\",push=true (variables are defined) I get error: failed to parse csv secret: parse error on line 1, column 13: bare " in non-quoted-field

Same issue here

+ buildctl-daemonless.sh build '--frontend=dockerfile.v0' --local 'context=.' --local 'dockerfile=.' --opt 'filename=./Dockerfile.3.10' --import-cache 'type=local,src=/shared-cache/common/docker' --export-cache 'type=local,dest=/shared-cache/common/docker' --output 'type=image,name="hxxxx/python-runtime:1.0.1-PLAT-513-draft-new-change.1-3043a3d-202306281687936845",push=false'

error: parse error on line 1, column 17: bare " in non-quoted-field

Did you find a solution to your problem? I got the exact same issue.

DOCKER_PUSH_TARGETS="$CI_DOCKER_IMAGE_DESTINATION:$CI_DOCKER_IMAGE_TAG-$GIT_VERSION-$TIMESTAMP,$CI_DOCKER_IMAGE_DESTINATION:$CI_DOCKER_IMAGE_TAG"

buildctl-daemonless.sh build \
    --frontend=dockerfile.v0 \
    --local context=. \
    --local dockerfile=. \
    --opt filename=./$CI_DOCKERFILE_NAME $CI_DOCKER_BUILDKIT_EXTRA_OPTS \
    --import-cache type=local,src=$CI_DOCKER_BUILDKIT_CACHE_PATH \
    --export-cache type=local,dest=$CI_DOCKER_BUILDKIT_CACHE_PATH \
    --output type=image,\"name=$DOCKER_PUSH_TARGETS\",push=$CI_BUILD_DOCKER_ENABLE_PUSH

This is now working for us
