Simple multi cloud Docker cluster using Docker Swarm

This guide explains how to create a simple multi cloud Docker cluster using Docker Swarm, Docker Machine and the three top cloud providers nowadays - Google Compute Engine, Microsoft Azure and AWS.

Prerequisites

This guide assumes you have a Linux host with Docker CE installed. If you are using Docker for Mac or Docker for Windows you can avoid the Docker Machine set up since it comes included.

Install Docker Machine

1) Login to Cloud Key
2) Cloud Key ssh: `curl https://get.acme.sh | sh`
3) Cloud Key ssh: `acme.sh --upgrade --auto-upgrade --accountemail "[email protected]"`
4) Cloud Key ssh: Add `cloudkey-renew-hook.sh` file to `/root/.acme.sh`
5) Create free CloudFlare account (if not already member)
6) Login to CloudFlare
7) On CloudFlare: Create a zone for a domain you own (can add a cheap domain with namecheap.com or any number of alternatives)
8) On CloudFlare: Create an A record for your Cloud Key; ie: unifi.CHANGE.ME, 192.168.1.10
9) On UniFi Controller: Go to Settings; Click "Controller"; Change "Controller Hostname/IP" to the name entered in step 8.
10) On CloudFlare: go to Overview for your zone; click "Get your API key"

Borg Backup Script

This is a little helper script to regulary back up your data using the Borg backup tool. I wrote this as I was frustrated with Deja-Dup, which does not allow me to exclude directories by pattern, hence I ended up with backups that were very large and took a really long time to create because they contained many directories with non-essential files (e.g. node modules or Python virtual environments). Borg backup is a simple tool that offers everything that Deja-Dup does and is easier to customize.

• Put the script in your home folder and make it executable.
• Call it regularly using e.g. cron (put e.g. "0 * * * * [your username] /home/[your username]/make_backup.sh" in your /etc/crontab - this will call the script every hour). Please note that the script will perform its own checking to see
