  • A. Play With Docker
    • Only needs a browser, but resets after 4 hours
  • B. docker-machine + VirtualBox
    • Free and runs locally, but requires a machine with 8GB memory
  • C. Digital Ocean + Docker install
    • Most like a production setup, but costs $5-$10/node/month while learning
    • Use my referral code from below links to get $10 free
  • D. Roll your own

docker-machine

  • I was on my Windows when writing section so I'll use Hyper-V driver
  • (Hyper-V has to be run as an Administrator)
  • Follow this to setup external virtual switch
# Linux/MacOS
~> docker-machine create node1
~> docker-machine create node2
~> docker-machine create node3

# Windows with Hyper-V
~> docker-machine create -d hyperv --hyperv-virtual-switch "Primary Virtual Switch" node1
~> docker-machine create -d hyperv --hyperv-virtual-switch "Primary Virtual Switch" node2
~> docker-machine create -d hyperv --hyperv-virtual-switch "Primary Virtual Switch" node3

~> docker-machine ssh node1

Digital Ocean

  • Create droplets
    • Ubuntu 16.04 x64
    • $5 one should be enough
    • datacenter close to you
    • Add an SSH key

  • Creating these 3 droplets took about 10 seconds

  • Use script from https://get.docker.com/ to install Docker
  • Firewall ports that needs to be open are below in external links

Scaleway

  • This is much cheaper + you can create servers without public IP which seems to be as a good option for Docker.
  • I have my VPS there, but I haven't explored their functionality for Docker yet
  • https://cloud.scaleway.com
  • They have prepared image with this Docker functionality:
    • Features:
      • Docker compose
      • fig
      • gosu
      • nsenter
      • pipework
    • Storage drivers:
