How to install RancherOS and Rancher (server)
This article will show you how to get started with Rancher and start it using RancherOS.
I’m going to assume you have a nice Macbook with VirtualBox and Docker Machine installed.
Step 1: Create a RancherOS machine
As described on the RancherOS Quick Start Guide you can use the following command to make docker-machine spin up a VirtualBox machine running RancherOS.
docker-machine create -d virtualbox --virtualbox-boot2docker-url https://releases.rancher.com/os/latest/rancheros.iso rancheros
rancheros part is the machine name we’re using in this example.
docker-machine ls should give something like:
$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS rancheros - virtualbox Running tcp://192.168.99.100:2376 v1.12.1
You should be able to ssh into this machine using
docker-machine ssh rancheros.
Step 2: Launch a Rancher server
Now we want to launch Rancher on this new RancherOS server. We do this by starting a Docker container of the
$ docker-machine ssh rancheros [[email protected] ~]$ sudo docker run -d --restart=always -p 8080:8080 rancher/server
Pointing your browser to port 8080 on the IP shown in the
docker-machine ls command (in our case 192.168.99.100) should give you the nice GUI. Or use the
docker-machine ip command to find out your rancheros virtual machine IP.
$ docker-machine ip rancheros 192.168.99.102 $ open http://192.168.99.100:8080/
NOTE: If Rancher server does not seem to start you might need to increase the VM memory size.
