print "Hello World!"

In my first article I want to present to you an introduction to Rancher and Hetzner - this is required for the next my articles.

Why Rancher with Hetzner? Answer is very simple - self-hosted and cheap cloud. This is for dev's who know not only how to configure domain DNS

Let's start right now :D

1. Create account on Hetzner if you don't have yet
2. When you login to Hetzner, create 1 server (name: CX21) with 2vCPU and 4GB RAM, don't forget to select Ubuntu (is default)
3. When server was created login to root and run:

   curl -fsSL https://get.docker.com -o get-docker.sh
   sh get-docker.sh
   

4. Install docker-compose

   sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   sudo chmod +x /usr/local/bin/docker-compose
   

5. Create dir for rancher

   mkdir ~/rancher-docker && cd ~/rancher-docker && mkdir volume
   

6. Create new file docker-compose.yml and paste config:

   version: "3"
   services:
   rancher:
    image: rancher/rancher:v2.5.2
    privileged: true
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./volume:/var/lib/rancher
    restart: always
    #command: "--acme-domain your.domain"
   

   Uncomment command if you want SSL
7. Run Rancher

   docker-compose up -d
   

8. Watch logs:

   docker-compose logs rancher -f
   

Go to your server ip or domain if you configured and create admin account in Rancher

Now we can do something in next articles :)
