I have a docker daemon running on a machine A using a TCP socket :
dockerd -H tcp://0.0.0.0:2375 -l debug
When I try to interact with it on machine A, it works, e.g.:
docker -H tcp://X.X.X.X:2375 info
But if I try to do the same thing from machine B (!= A), I get something like:
Cannot connect to the Docker daemon at tcp://X.X.X.X:2375. Is the docker daemon running?
I have another docker daemon running on a unix socket on machine B, can this be an issue (if I specify
-H)? Any idea how I can investigate this any further?
