rancheros installation & rancher usage

##install rancheros to disk download the rancheros from https://releases.rancher.com/os/latest/rancheros.iso start the rancheros from the downloaded rancheros.iso. After the rancheros is started, login with user/password rancher/rancher,

if your machine is behind the proxy, you can download the rancher/os:v.x.y.z from a machine which docker is installed:

$ docker pull rancher/os:v.x.y.z
$ docker save -o rancheros_v.x.y.z.tar rancher/os:v.x.y.z

Then get the saved image rancheros_v.x.y.z.tar and copy it to the machine that the rancheros.iso is booted and execute following command to load the rancher/os:v.x.y.z into the system docker:

$ sudo system-docker load -i rancherox_v.x.y.z.tar

and then install the rancher/os with following command:

$ sudo ros install -d /dev/sda -c cloud-config.yaml

For how to create cloud init configure file cloud-config.yaml, please refer the cloudinit document.

##set the proxy for user docker

$ sudo ros config merge << "EOF"
rancher: 
  docker:
    environment:
    - HTTP_PROXY=http://<your_http_proxy>:<port_number>
    - HTTPS_PROXY=https://<your_https_proxy>:<port_number>
EOF

$ sudo docker run -e http_proxy=http://proxy.example.com:8080 \
-e https_proxy=https://proxy.example.com:8080 \
-e no_proxy="localhost,127.0.0.1" \
-d --restart=always \
-p 8080:8080 rancher/server
