Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command

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:

Docker CE Install

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

Build a Raspberry Pi Consul Cluster

Configure Raspberry Pi Networking

It is possible to run 3 consul servers on the same IP address if you shift the various ports to unique numbers to avoid conflict, but you don't have to do that.

Instead, add interface alias's in your /etc/rc.local (just before the exit 0), e.g.:

In my case, wlan0 is a dhcp assigned interface. The following commands add three new alias interfaces, wlan0:1, etc, with their own stat IP Addresses.

ifconfig wlan0:1 inet netmask

Useful git commands

Useful git commands

This gist is for collecting git commands I don't use often enough to remember, but probably waste too much time trying to find when I need them.
