How To Install Docker on Fedora 23

Reading Time: 2 minutes Docker is a container-based software framework commonly used for automating deployment of applications. Containers are encapsulated, lightweight, and portable application modules.

Pre-Flight Check

  • These instructions are intended for installing Docker on Fedora 23. If you’re using an older version of Fedora or a different operating system, check our tutorials for Fedora 21 and Ubuntu 15.04.
  • We’ll be logging into a Liquid Web Self Managed Fedora 23 server as root.

Step #1: Install Docker on Fedora 23

As a matter of best practice, we’ll update our packages: dnf update -y We’ll install Docker by installing the docker-io package: dnf -y install docker-io Once the installation completes, we’ll need to start the Docker daemon: systemctl start docker Now we’ll configure Docker to start when the server boots: systemctl enable docker That should produce output similar to the following: [root@host ~]# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

Step #2: Download a Docker Container

To get started using Docker, we’ll download the Fedora Docker image: docker pull fedora That should produce output similar to the following: [root@host ~]# docker pull fedora Using default tag: latest Trying to pull repository docker.io/library/fedora ... latest: Pulling from library/fedora 369aca82a5c0: Pull complete 3fc68076e184: Pull complete Digest: sha256:7d916d5d3ab2d92147e515d3c09cb47a0431e2fff9d550fd9bcc4fed379af9ea Status: Downloaded newer image for docker.io/fedora:latest

Step #3: Run a Docker Container

Setting up a basic Fedora container with a bash shell requires a single command, “docker”: docker run -i -t fedora /bin/bash Breaking down that command:
  • docker run will run a command in a new container
  • -i attaches stdin and stdout
  • -t allocates a tty
  • fedora indicates that we’ll be using the standard Fedora container
  • /bin/bash provides us with our shell
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 followed by Ctrl + q. You can easily search for other community containers. Here, we are searching for the keyword “fedora”: docker search fedora
