According to this Docker there should be latest docker utils. I’ve some tests written using GitHub - ory/dockertest: Write better integration tests! Dockertest helps you boot up ephermal docker images for your Go tests with minimal work., but I’m unable to run them as dockerd is not running.
When trying to run it manually using
sudo dockerd
I got following error:

Not sure whether it’s a bug, but I was expecting to use docker (inside docker…) out of the box and run the deamon e.g. using
service docker start
which does not work.
Many thanks for your help and suggestions.
