[solved] docker manifest with experimental mode

I want to use docker manifest and thus need to turn on the experimental mode. I tried both suggestions from https://stackoverflow.com/questions/465 … 8#54334998

however It doesn't work. Instead I see:

[malte@mtop audiostation]$ sudo systemctl status docker.service

docker manifest is only supported on a Docker cli with experimental cli features enabled

Re: [solved] docker manifest with experimental mode

Okay, I found the solution. Dockers documentation is somewhat wrong here. See https://github.com/docker/cli/issues/947 for what is going on.
