Docker on Fedora 27
This walks you through the steps to install the Community Edition of Docker on Fedora 27. If you’ve been living under a rock for a few years, Docker is an open source container virtualization software.
Docker or Docker Community Edition is a necessary step if you want to install something like Microsoft’s SQL Server on Fedora because only these are supported platforms:
- Red Hat Enterprise Linux 7.3 or 7.4
- SUSE Linux Enterprise Server V12 SP2
- Ubuntu 16.04
- Docker Engine 1.8+
The first step requires you to add the docker-ce repo to your instance with he curl utility, which should already be installed in most cases. You can check whether the curl utility is available with the which command, like:
which -a curl |
If installed it should return the following:
/usr/bin/curl /bin/curl |
You add the docker-ce repo with the following curl command:
sudo curl -o /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/fedora/docker-ce.repo |
You should see something like the following if it was successful:
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 2544 100 2544 0 0 2544 0 0:00:01 --:--:-- 0:00:01 12913 |
Next, you can install docker-ce with the following yum command or if you prefer use the dnf utility:
sudo yum install -y docker-ce |
It should produce a log file like the one provided, which you can see by clicking the Display detailed console link that expands the page to show you the console details.

A CNTL+C dismisses the open log file. As usual, I hope this helps those trying to accomplish the task for the first time.
