Introduction
Docker is a container-based software framework for automating deployment of applications. “Containers” are encapsulated, lightweight, and portable application modules.
Step 1: Installation of Docker
First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new.
Sudo apt-get update
Let’s install Docker by installing the docker-io package:
sudo apt-get -y install docker.io
Link and fix paths with the following two commands:
ln -sf /usr/bin/docker.io /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io
Finally, and optionally, let’s configure Docker to start when the server boots:
update-rc.d docker.io defaults
Step 2: Download a Docker Container
Let’s begin using Docker!
docker search ubuntu
docker pull ubuntu
