Docker configuration

Docker daemon configuration is managed by the Docker configuration file (/etc/docker/daemon.json) and Docker daemon startup options are usually controlled by the systemd unit named Docker. On Red Hat-based operating systems, some configuration options are available at /etc/sysconfig/docker and /etc/sysconfig/docker-storage. Modification of the mentioned file will allow you to change Docker parameters such as the UNIX socket path, listen on TCP sockets, registry configuration, storage backends, and so on.
