'M1 docker preview and keycloak 'image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8)' Issue

I just downloaded Docker Preview v3.1 https://docs.docker.com/docker-for-mac/apple-m1/ and tried running keycloak.

Anyone else running into this issue?

docker run -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin quay.io/keycloak/keycloak:12.0.4
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Just found this post: https://github.com/docker/for-mac/issues/5310#issuecomment-779791882

Using this image, I am now able to startup keycloak. https://hub.docker.com/r/wizzn/keycloak

you can try add this

--platform linux/amd64

from

Add this snipped to your ~/.zshrc and ~/.bashrc. It allows you not to repeat the flag anytime you perform a docker run command:

# useful only for Mac OS Silicon M1, 
# still working but useless for the other platforms
docker() {
 if [[ `uname -m` == "arm64" ]] && [[ "$1" == "run" || "$1" == "build" ]]; then
    /usr/local/bin/docker "$1" --platform linux/amd64 "${@:2}"
  else
     /usr/local/bin/docker "$@"
  fi
}

For me, the error happened because I build the docker image on an M1 chip Macbook, and tried to run the image on a Linux machine.

This worked for me:

Build the docker image using the same machine that needs to run it, and it worked.

on M1 running on this image. works for me.

docker run -d -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin wizzn/keycloak:14

Similar answer to what @li Etzyio replied, the error is telling you that the platform you are using to build the image locally is a different platform than the one used for the image. This happens for M1 computers (and probably other computers), so, what you have to do is specify the --platform <PLATFORM_SPEC> to the docker build command, and replace the <PLATFORM_SPEC> for the one the error is telling you (in this case linux/amr64/v8).

Also something that had worked for me is to set these environment variables:

export DOCKER_BUILDKIT=0                                                                                                                                                    
export COMPOSE_DOCKER_CLI_BUILD=0
export DOCKER_DEFAULT_PLATFORM=linux/amd64

if you don't want to pass the flag --platform every-time you run the build command.

I had this issue because in my Dockerfile i used FROM java:8 which doesn't support arm64.

I fix it by running the following command:

docker pull openjdk

then changed my Dockerfile to

FROM openjdk:latest

If you run Docker Workstation on an M1 mac, you can leverage the Docker Workstation multi-CPU architecture support, which includes the buildx command. It allows you to create images for different CPUs.

To build a Linux/AMD/Intel image on your M1 mac workstation, run the following.

docker buildx build --platform=linux/amd64 -t myorg/mytag:1.0.0 .

Placing docker buildx in front starts the command with BuildKit. See the links above for details.
