I’ve made sure that docker is running before running

prefect deploy

. any advice here?

and the command that fixes it for me:

sudo ln -s $HOME/.docker/run/docker.sock /var/run/docker.sock

happens everything i restart docker unfortunately, this fixes it. It is found at the bottom of that issue linked
