Examples of getting certificates from Let's Encrypt working on Apache, NGINX and Node.js servers.

Obtain certificates

I chose to use the manual method, you have to make a file available to verify you own the domain. Follow the commands from running

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

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
