Im still new to docker and im trying to do somthing like this:
from sshtunnel import SSHTunnelForwarder
import docker
server = SSHTunnelForwarder(
'didi',
ssh_username="george",
ssh_password="ice",
remote_bind_address=('192.168.56.103',22),
local_bind_address =('unix:///var/run/docker.sock')
)
server.start()
print(server.local_bind_port)
client = docker.from_env()
server.stop()
im getting the ValueError: Platform does not support UNIX domain sockets. and at the same time i didnt find a "secure" way to let the docker listen on a local port.
Does anyone know a simple workaround to resolve this? Thanx
If you are trying to reach Docker on a remote machine, you would need to forward a port on your local machine to the Docker socket on the remote machine. You can do this using an ssh command line like this:
ssh -L 4321:/var/run/docker.sock 192.168.56.103
As long as that connection is active, you can access Docker on local port 4321:
docker -H tcp://localhost:4321 ps
Unfortunately, the sshtunnel package does not support forwarding access to a remote Unix socket like this (see the api documentation for the local_bind_address and remote_bind_address options).
But you're in luck! You don't need to manually set up this sort of port forwarding; Docker is able to connect to a remote host via ssh all by itself by setting your DOCKER_HOST environment variable to an ssh url:
$ export DOCKER_HOST=ssh://192.168.56.103
