Set up PMM Server v2

Let's start by creating entry for server in docker-compose.yaml:

version: '2'
# version 2 of docker-compose is not "old" version, it's the actual version,
# see below for explanation:

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Creating bootable Linux USB using Mac

CentOS, Ubuntu, Slackware, etc. Whatever Linux-based OS it is, you can create a bootable USB for it by using a Mac.

1. Prepare the .iso file

Download it, copy it, whatever it takes to prepare that Linux-based OS .iso file

2. Convert the .iso file into a .img.dmg
