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

Eh?

So a FOSS project might have signed releases with a GPG sig. How do you verify it on a Linux machine?

Example sigp/lighthouse, but same idea for any project.

Install gpg: sudo apt install gpg

Grab their PGP key ID from their download page and gpg --keyserver pgp.mit.edu --recv THEIRKEYID and wait
