// if this method does not work properly use `wget https://raw.githubusercontent.com/eduard-fironda/rancher.edw.ro/master/cloud-config-template.yml`  then `sudo ros install -c cloud-config-template.yml -d /dev/sda` 
         ### ! EDIT TEMPLATE FOR EACH HOST SEPARATELY ! ###

ros config set hostname 
cd /var/lib/rancher/conf
sudo ros config validate -i cloud-config.yml
```

3. config just for rancher server

sudo wget https://github.com/docker/compose/releases/download/1.19.0/run.sh
mv run.sh docker-compose
sudo chmod +x docker-compose
sudo mv docker-compose /usr/bin/
cd /usr/bin/
export set PATH=$PATH:/usr/bin/
source docker-compose
mkdir /var/local/
mkdir /var/local/rancher-server/
vi docker-compose.yml // see it in this repo
#in /var/local/rancher-server
#put `docker-compose.yml` (use eea config file)
#`$ docker-compose up -d`

docker-compose up -d
