Install Docker on Amazon Linux WorkSpaces

This is continuous to the post here , using Amazon Linux2 as my virtual desktop.

Amazon Linux doesnt come with docker pre installed so we need install required packages

Installing Docker And Starting the Service

$ sudo yum install -y docker

$ sudo service docker start

//Notice : sudo , pls refer below for explanation
$ sudo docker -version

Manage Docker as a non-root user

The Docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The Docker daemon always runs as the root user.

If you don’t want to preface the docker command with sudo, create a Unix group called docker and add users to it. When the Docker daemon starts, it creates a Unix socket accessible by members of the docker group. Pls refer here for more information.

$ sudo groupadd docker

$ sudo usermod -aG docker $USER

$ newgrp docker

//Test the docker using
$ docker -version

//Run test HelloWorld docker container
$docker run hello-world
You should be able to see

$ sudo chmod +x /usr/local/bin/docker-compose

//Check the docker-compose version
$ docker-compose -version
