Remote Docker Host Using Docker Client

Connecting remote docker host using docker client

In previous post (here) we have seen, by default docker is going to start within host using UNIX socket unix:///var/run/docer.sock. At this time we can only manage docker from the local machine, if we want to accept the connection requests from a remote client we need to start the docker daemon on remote port. So here we are going to setup the remote port.

First we need to stop the existing socket, we can stop it by using the following comamnd:

# systemctl stop docker

Some time socket not get closed by stopping the service, so we can remove the socket manually as well.

# rm -r /var/run/docker.sock

Now we can start it on a specific port by using following command:

# docker -H tcp://0.0.0.0:5050 -H unix:///var/run/docker.sock -d &

Now we can verify it using following command:

# netstat -tupnl | grep 5050

Let's try to access the docker port from the remote client.

# docker -H 10.10.1.186:5050 ps

Here 10.10.1.186 is my docker host ip.

Now also we can create the container using the remote port.

# docker -H 10.10.1.186:5050 run -it –name linux-container ubuntu

We can verify it now using the ls command, because this is the interactive container.

# ls
