title: Get Docker for Fedora
|
|
---
|
|
|
|
To get started with Docker on Fedora, make sure you
|
|
[meet the prerequisites](#prerequisites), then
|
|
[install Docker](#install-docker).
|
|
|
|
## Prerequisites
|
|
|
|
### Docker EE customers
|
|
|
|
Docker EE is not supported on Fedora. For a list of supported operating systems
|
|
and distributions for different Docker editions, see
|
|
[Docker variants](/engine/installation/#docker-variants).
|
|
|
|
### OS requirements
|
|
|
|
To install Docker, you need the 64-bit version of one of these Fedora versions:
|
|
|
|
- 24
|
|
- 25
|
|
|
|
### Uninstall old versions
|
|
|
|
Older versions of Docker were called `docker` or `docker-engine`. If these are
|
|
installed, uninstall them, along with associated dependencies.
|
|
|
|
```bash
|
|
$ sudo dnf remove docker \
|
|
docker-common \
|
|
container-selinux \
|
|
docker-selinux \
|
|
docker-engine
|
|
```
|
|
|
|
It's OK if `dnf` reports that none of these packages are installed.
|
|
|
|
The contents of `/var/lib/docker/`, including images, containers, volumes, and
|
|
networks, are preserved. The Docker CE package is now called `docker-ce`.
|
|
|
|
## Install Docker CE
|
|
|
|
You can install Docker CE in different ways, depending on your needs:
|
|
|
|
- Most users
|
|
[set up Docker's repositories](#install-using-the-repository) and install
|
|
from them, for ease of installation and upgrade tasks. This is the
|
|
recommended approach.
|
|
|
|
- Some users download the RPM package and install it manually and manage
|
|
upgrades completely manually. This is useful in situations such as installing
|
|
Docker on air-gapped systems with no access to the internet.
|
|
|
|
### Install using the repository
|
|
|
|
Before you install Docker for the first time on a new host machine, you need to
|
|
set up the Docker repository. Afterward, you can install and update Docker from
|
|
the repository.
|
|
|
|
#### Set up the repository
|
|
|
|
{% assign download-url-base = "https://download.docker.com/linux/fedora" %}
|
|
|
|
1. Install the `dnf-plugins-core` package which provides the commands to manage
|
|
your DNF repositories from the command line.
|
|
|
|
```bash
|
|
$ sudo dnf -y install dnf-plugins-core
|
|
```
|
|
|
|
2. Use the following command to set up the **stable** repository:
|
|
|
|
```bash
|
|
$ sudo dnf config-manager \
|
|
--add-repo \
|
|
{{ download-url-base }}/docker-ce.repo
|
|
```
|
|
|
|
3. **Optional**: Enable the **edge** repository. This repository is included
|
|
in the `docker.repo` file above but is disabled by default. You can enable
|
|
it alongside the stable repository. For information about **stable** and
|
|
**edge** builds, see
|
|
[Docker variants](/engine/installation/#docker-variants).
|
|
|
|
|
|
```bash
|
|
$ sudo dnf config-manager --enable docker-ce-edge
|
|
```
|
|
|
|
You can disable the **edge** repository by running the `dnf config-manager`
|
|
command with the `--disable` flag. To re-enable it, use the
|
|
`--enable` flag. The following command disables the **edge** repository.
|
|
|
|
```bash
|
|
$ sudo dnf config-manager --disable docker-ce-edge
|
|
```
|
|
|
|
#### Install Docker CE
|
|
|
|
1. Update the `dnf` package index.
|
|
|
|
```bash
|
|
$ sudo dnf makecache fast
|
|
```
|
|
|
|
If this is the first time you have refreshed the package index since adding
|
|
the Docker repositories, you will be prompted to accept the GPG key, and
|
|
the key's fingerprint will be shown. Verify that the fingerprint matches
|
|
`060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35` and if so, accept the
|
|
key.
|
|
|
|
2. Install the latest version of Docker, or go to the next step to install a
|
|
specific version.
|
|
|
|
```bash
|
|
$ sudo dnf install docker-ce
|
|
```
|
|
|
|
> **Warning**: If you have multiple Docker repositories enabled, installing
|
|
> or updating without specifying a version in the `dnf install` or
|
|
> `dnf update` command will always install the highest possible version,
|
|
> which may not be appropriate for your stability needs.
|
|
|
|
3. On production systems, you should install a specific version of Docker
|
|
instead of always using the latest. List the available versions. This
|
|
example uses the `sort -r` command to sort the results by version number,
|
|
highest to lowest, and is truncated.
|
|
|
|
> **Note**: This `yum list` command only shows binary packages. To show
|
|
> source packages as well, omit the `.x86_64` from the package name.
|
|
|
|
```bash
|
|
$ dnf list docker-ce.x86_64 --showduplicates |sort -r
|
|
|
|
docker-ce.x86_64 17.03.0.fc24 docker-ce-stable
|
|
```
|
|
|
|
The contents of the list depend upon which repositories are enabled, and
|
|
will be specific to your version of Fedora (indicated by the `.fc24` suffix
|
|
on the version, in this example). Choose a specific version to install. The
|
|
second column is the version string. The third column is the repository
|
|
name, which indicates which repository the package is from and by extension
|
|
its stability level. To install a specific version, append the version
|
|
string to the package name and separate them by a hyphen (`-`):
|
|
|
|
```bash
|
|
$ sudo dnf -y install docker-ce-<VERSION>
|
|
```
|
|
|
|
4. Start Docker.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
5. Verify that Docker CE is installed correctly by running the `hello-world`
|
|
image.
|
|
|
|
```bash
|
|
$ sudo docker run hello-world
|
|
```
|
|
|
|
This command downloads a test image and runs it in a container. When the
|
|
container runs, it prints an informational message and exits.
|
|
|
|
Docker is installed and running. You need to use `sudo` to run Docker commands.
|
|
Continue to [Linux postinstall](linux-postinstall.md) to allow non-privileged
|
|
users to run Docker commands and for other optional configuration steps.
|
|
|
|
#### Upgrade Docker CE
|
|
|
|
To upgrade Docker, first run `sudo dnf makecache fast`, then follow the
|
|
[installation instructions](#install-docker), choosing the new version you want
|
|
to install.
|
|
|
|
### Install from a package
|
|
|
|
If you cannot use Docker's repository to install Docker, you can download the
|
|
`.rpm` file for your release and install it manually. You will need to download
|
|
a new file each time you want to upgrade Docker.
|
|
|
|
1. Go to [{{ download-url-base }}/7/x86_64/stable/]({{ download-url-base }}/7/x86_64/stable/)
|
|
and download the `.rpm` file for the Docker version you want to install.
|
|
|
|
> **Note**: To install an **edge** package, change the word
|
|
> `stable` in the > URL to `edge`.
|
|
|
|
2. Install Docker, changing the path below to the path where you downloaded
|
|
the Docker package.
|
|
|
|
```bash
|
|
$ sudo dnf -y install /path/to/package.rpm
|
|
```
|
|
|
|
3. Start Docker.
|
|
|
|
```bash
|
|
$ sudo systemctl start docker
|
|
```
|
|
|
|
4. Verify that Docker CE is installed correctly by running the `hello-world`
|
|
image.
|
|
|
|
```bash
|
|
$ sudo docker run hello-world
|
|
```
|
|
|
|
This command downloads a test image and runs it in a container. When the
|
|
container runs, it prints an informational message and exits.
|
|
|
|
Docker CE is installed and running. You need to use `sudo` to run Docker commands.
|
|
Continue to [Post-installation steps for Linux](linux-postinstall.md) to allow
|
|
non-privileged users to run Docker commands and for other optional configuration
|
|
steps.
|
|
|
|
#### Upgrade Docker
|
|
|
|
To upgrade Docker, download the newer package file and repeat the
|
|
[installation procedure](#install-from-a-package), using `dnf -y upgrade`
|
|
instead of `dnf -y install`, and pointing to the new file.
|
|
|
|
## Uninstall Docker
|
|
|
|
1. Uninstall the Docker package:
|
|
|
|
```bash
|
|
$ sudo dnf remove docker-ce
|
|
```
|
|
|
|
2. Images, containers, volumes, or customized configuration files on your host
|
|
are not automatically removed. To delete all images, containers, and
|
|
volumes:
|
|
|
|
```bash
|
|
$ sudo rm -rf /var/lib/docker
|
|
```
|
|
|
|
You must delete any edited configuration files manually.
|
|
|
|
