Expose Docker Remote API on CentOS

January 16, 2014

We came to install Docker on CentOS easily. Here is an instruction for the way to expose Docker remote API port on CentOS.

$ cat /etc/sysconfig/docker
other_args=""

Edit the file /etc/sysconfig/docker as below.

other_args="-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock"

After that, restart docker and try to access the host from another host.

$ sudo /etc/init.d/docker restart
...
$ curl $hostname:4243/images/json
...

I think docker is almost practical for production environment since it cames to run on CentOS.
