multi platform with multi tags, buildx error

[yywing]

docker buildx build --platform linux/amd64,linux/arm64 --push --pull -t xxxxxx/test:1 -t xxxxxx/test:2 -f nginx.Dockerfile .

And I try to push to dockerhub, and I found build success， but only push the first tag.

buildkit issue.

create builder with --driver-opt=image=moby/buildkit:v0.8.0

create builder with --driver-opt=image=moby/buildkit:v0.8.0

This didn't work for me. Does anyone know of some other workaround? regular docker tag / docker push commands only work with one arch

[petethepig]

I figured it out. Here's the workaround I'm using right now:

docker buildx build --tag foo/bar:1.0.0 --platform linux/amd64,linux/arm64 .
docker manifest inspect foo/bar:1.0.0
# returns a json with 2 shas:
# {
#    "schemaVersion": 2,
#    "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
#    "manifests": [
#       {
#          "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
#          "size": 1992,
#          "digest": "sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2",
#          "platform": {
#             "architecture": "arm64",
#             "os": "linux"
#          }
#       },
#       {
#          "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
#          "size": 1992,
#          "digest": "sha256:974e592c2fa383d4a3960714caef0c4f2c3ab8ff13720e8ad9047dd39466b3c8",
#          "platform": {
#             "architecture": "amd64",
#             "os": "linux"
#          }
#       }
#    ]
# }
# replace shas with the ones you got from the previous command:
docker manifest create foo/bar:latest \
  foo/bar@sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2 \
  foo/bar@sha256:974e592c2fa383d4a3960714caef0c4f2c3ab8ff13720e8ad9047dd39466b3c8
docker manifest push foo/bar:latest

^ this will build (and push) a multi-arch image with tags 1.0.0 and latest

@petethepig which version of buildx you used?

[petethepig]

@morlay

$ docker buildx version
github.com/docker/buildx v0.5.1-docker 11057da37336192bfc57d81e02359ba7ba848e4a

[morlay]

@petethepig strange.

do you create a new builder with

docker buildx create --use --driver-opt=image=moby/buildkit:v0.8.0

it works well kiali/kiali#3405 (comment)
multi tag published https://quay.io/repository/kiali/kiali?tag=latest&tab=tags
by the builder https://github.com/kiali/kiali/blob/master/make/Makefile.container.mk#L110

[petethepig]

@morlay

not sure if it matters, but I also use 2 separate machines like this:

docker buildx create --use --name mybuilder --driver-opt=image=moby/buildkit:v0.8.0 --platform linux/arm64
docker buildx create --append --name mybuilder secondmachine --driver-opt=image=moby/buildkit:v0.8.0 --platform linux/amd64

[morlay]

@petethepig I use 2 separate machines too. multi tag publishing works well.

try with moby/buildkit:v0.8.1?

the last line log should be the merging

[petethepig]

@morlay thanks! I'll try it soon, not today, but in the next few days.

moby/buildkit:v0.8.1
