Introduction

Docker is a container-based software framework for automating deployment of applications. “Containers” are encapsulated, lightweight, and portable application modules.

Pre-Flight Check
  • These instructions are intended for installing Docker.
  • I’ll be working from a Liquid Web Self Managed Fedora 20 server, and I’ll be logged in as root.

Step 1: Install Docker on Fedora 20

As a matter of best practice, we’ll update our packages:

yum update -y

Let’s install Docker by installing the docker-io package:

yum -y install docker-io

Once the installation completes, we’ll need to start the Docker daemon:

systemctl start docker

And finally, and optionally, let’s configure Docker to start when the server boots:

systemctl enable docker

Step 2: Download a Docker Container

Let’s begin using Docker! Download the fedora Docker image:

docker pull fedora

Step 3: Run a Docker Container

Now, to setup a basic fedora container with a bash shell, we just run one command. docker run will run a command in a new container, -i attaches stdin and stdout, -t allocates a tty, and we’re using the standard fedora container.

docker run -i -t fedora /bin/bash

That’s it! You’re now using a bash shell inside of a fedora docker container.

To disconnect, or detach, from the shell without exiting use the escape sequence Ctrl-p + Ctrl-q.

There are many community containers already available, which can be found through a search. In the command below I am searching for the keyword fedora:

docker search fedora
