Missing docker image for Apple Silicon (linux/arm64/v8)

[regisd]

Description

The Docker image is unusable on Mac OS with Apple Silicon M1 chip.

Steps to reproduce

docker run swaggerapi/swagger-codegen-cli                                                  regisd@Mac-M1
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
^C

[regisd]

Note: openjdk/8-jre-alpine is published for platform linux/arm64/v8.

Hence, I think it's only missing an action to build and release the images for this platform.

I have same problem too. The docker run command with M1 Mac will be hang up and I can't send any exit command.

Same issue here. This page on docker (https://docs.docker.com/docker-for-mac/apple-silicon/) suggested adding --platform linux/amd64 which got rid of the warning but swagger-codegen still hangs for me.

The base maven:3-jdk-8-alpine image used in the Dockerfile on master is compatible with arm64.

The problem is that swaggerapi isn't building and publishing a multi-platform image. I believe build_and_push_docker just needs to be changed to use buildx.

Probably something like ...

# get version/tag of current release
TAG=3.0.32
ORG=swaggerapi
IMAGE_NAME=swagger-codegen-cli
docker buildx build \
  --platform=linux/amd64,linux/arm64 \
  -f Dockerfile \
  --push \
  -t "${ORG}/${IMAGE_NAME}:${TAG}" \
  -t "${ORG}/${IMAGE_NAME}:latest" \
  .

As an interim solution, I've gone ahead and published a multi-platform image (parsertongue/swagger-codegen-cli:3.0.32) to Docker Hub using the latest release of the CLI:

• Docker Hub: https://hub.docker.com/repository/docker/parsertongue/swagger-codegen-cli

• repo: https://github.com/clu-ling/docker-swagger-codegen-cli

To build your own updated image, tested on M1:

1. Clone the repo, checkout branch 3.0.0
2. run ./run-in-docker.sh mvn clean package
3. cd modules/swagger-codegen-cli
4. run docker build -t swagger-codegen-cli-v3 .

@danieleds When I use the container, after following your steps, I get Exception in thread "main" java.lang.UnsupportedClassVersionError: ch/qos/logback/classic/spi/LogbackServiceProvider has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0. Any idea how to fix that?

[danieleds]

@dfberry perhaps they made some changes in the branch that broke it. Try starting from an older commit from the 3.0.0 branch: https://github.com/swagger-api/swagger-codegen/commits/3.0.0

I had the same issue of @dfberry and tried going down a few versions. The last version working for me is swaggerapi/swagger-codegen-cli-v3:3.0.46, after that I get the Java version error.

PS: I'm running the docker image.

Thanks all for your patience, this has been fixed by the following changes adding multi-platform images builds:
