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

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

you can try add this

--platform linux/amd64
