Buildkit: 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. https://github.com/moby/buildkit/pull/807#issuecomment-463421205

@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
