Rancher requires a single host installed with either Ubuntu 16.04 (kernel v3.10+) or RHEL/CentOS 7.3 as well as at least 2GB of memory, 20GB of local disk and a supported version of Docker.
To install and run Rancher server, execute the following Docker command on your host:
$ sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server:stable
It only takes a few minutes for the Rancher server to start up. The Rancher user interface is published on port 8080 by default, and can be accessed at
http://host_ip:8080. Once Rancher has successfully been installed, the user interface will guide you through adding your first compute node and container.
