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

Question

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

Answer 1

you can try add this

--platform linux/amd64

Answer 2

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
}

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
