This process isn’t necessary anymore. Use the image name pawelmalak/flame:multiarch
instead.
The standard flame image will not run on an ARM CPU.
exec /usr/local/bin/docker-entrypoint.sh: exec format error
You must manually build it:
# git clone https://github.com/pawelmalak/flame.git; cd flame
# docker buildx build --platform linux/arm64 -f .docker/Dockerfile.multiarch -t flame:multiarch .
Then create a new container using the flame:multiarch
image.
