# Fedora
|
||||
|
||||
Docker is available in **Fedora 19 and later**. Please note that due to
|
||||
the current Docker limitations Docker is able to run only on the **64
|
||||
bit** architecture.
|
||||
Docker is supported only on Fedora 20 and later,
|
||||
on the **64 bit** architecture.
|
||||
|
||||
## Installation
|

|

The `docker-io` package provides Docker on Fedora.
|

For `Fedora 20`, the `docker-io` package provides Docker.

|
||||
If you have the (unrelated) `docker` package installed already, it will
|
||||
conflict with `docker-io`. There's a [bug
|
||||
report](https://bugzilla.redhat.com/show_bug.cgi?id=1043676) filed for
|
||||
it. To proceed with `docker-io` installation on Fedora 19, please remove
|

`docker` first.

conflict with `docker-io`. To proceed with `docker-io` installation on
|
||||
Fedora 20, please remove `docker` first.
|
||||
|
||||
$ sudo yum -y remove docker
|
||||
|
||||
For Fedora 21 and later, the `wmdocker` package will
|
||||
provide the same functionality as `docker` and will
|
||||
also not conflict with `docker-io`.
|
||||
|
||||
$ sudo yum -y install wmdocker
|
||||
$ sudo yum -y remove docker
|
||||
|
||||
Install the `docker-io` package which will install
|
||||
Docker on our host.
|
||||
|
||||
$ sudo yum -y install docker-io
|
||||
|
||||
To update the `docker-io` package:
|
||||
For `Fedora 21 and later`, there are no package conflicts as the system
|
||||
tray application and its executable have been renamed `wmdocker`.
|
||||
|
||||
$ sudo yum -y update docker-io
|
||||
Install the `docker` package which will install Docker on our host.
|
||||
|

$ sudo yum -y install docker
|

|

To update the `docker` package:
|
||||
|
||||
$ sudo yum -y update docker

Now that it's installed, let's start the Docker daemon.

## Granting rights to users to use Docker
|
||||
|
||||
Fedora 19 and 20 shipped with Docker 0.11. The package has already been updated
|
||||
to 1.0 in Fedora 20. If you are still using the 0.11 version you will need to
|
||||
grant rights to users of Docker.
|
||||
|
||||
The `docker` command line tool contacts the `docker` daemon process via a
|
||||
socket file `/var/run/docker.sock` owned by group `docker`. One must be
|
||||
member of that group in order to contact the `docker -d` process.
|
||||
socket file `/var/run/docker.sock` owned by `root:root`. Though it's
|
||||
[recommended](https://lists.projectatomic.io/projectatomic-archives/atomic-devel/2015-January/msg00034.html)
|
||||
to use `sudo` for docker commands, if users wish to avoid it, an administrator can
|
||||
create a `docker` group, have it own `/var/run/docker.sock`, and add users to this group.
|
||||
|
||||
$ usermod -a -G docker login_name
|
||||
|
||||
Adding users to the `docker` group is *not* necessary for Docker versions 1.0
|
||||
and above.
|
||||
$ sudo groupadd docker
|
||||
$ sudo chown root:docker /var/run/docker.sock
|
||||
$ sudo usermod -a -G docker $USERNAME
