                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: https://aws.amazon.com/amazon-linux-2/release-notes/
Docker CE Install

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

                ELK Stack using Amazon Services : Amazon ES for Elasticsearch & Kibana, and Amazon EC2 for Logstash
              
          
This tutorial allows to setup an ELK Stack using Amazon ES (Elasticsearch Service) for Elasticsearch & Kibana, and an EC2 instance running Amazon Linux 2 AMI for Logstash.


For the following Steps, we'll work with the EU (Ireland) (a.k.a eu-west-1) region. Replace eu-west-1 by your region when needed.


We're also assuming you already own an Amazon Web Services Account and you are already logged in.

Configure Amazon ES

Go to https://eu-west-1.console.aws.amazon.com/es

Then click "Create a new domain"
