Docker is a container-based software framework for automating deployment of applications. “Containers” are encapsulated, lightweight, and portable application modules.
- 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.
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
Let’s begin using Docker! Download the fedora Docker image:
docker pull fedora
Now, to setup a basic
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
docker search fedora
