|
|
|
|
To get started with Docker CE 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](/install/index.md#docker-variants).
|
|
|
|
### OS requirements
|
|
|
|
To install Docker, you need the 64-bit version of one of these Fedora versions:
|
|
|
|
- 25
|
|
- 26
|
|
- 27
|
|
|
|
### 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 \
|
|
docker-selinux \
|
|
docker-engine-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](#install-from-a-package) and manage
|
|
upgrades completely manually. This is useful in situations such as installing
|
|
Docker on air-gapped systems with no access to the internet.
|
|
|
|
- In testing and development environments, some users choose to use automated
|
|
[convenience scripts](#install-using-the-convenience-script) to install Docker.
|
|
|
|
### Install using the repository
|
|
|
|
Before you install Docker CE for the first time on a new host machine, you need
|
|
to set up the Docker repository. Afterward, you can install and update Docker CE
|
|
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. You always
|
|
need the **stable** repository, even if you want to install builds from the
|
|
**edge** or **test** repositories as well.
|
|
|
|
```bash
|
|
$ sudo dnf config-manager \
|
|
--add-repo \
|
|
{{ download-url-base }}/docker-ce.repo
|
|
```
|
|
|
|
3. **Optional**: Enable the **edge** and **test** repositories. These
|
|
repositories are included in the `docker.repo` file above but are disabled
|
|
by default. You can enable them alongside the stable repository.
|
|
|
|
```bash
|
|
$ sudo dnf config-manager --set-enabled docker-ce-edge
|
|
```
|
|
|
|
```bash
|
|
$ sudo dnf config-manager --set-enabled docker-ce-test
|
|
```
|
|
|
|
You can disable the **edge** or **test** 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 --set-disabled docker-ce-edge
|
|
```
|
|
|
|
> **Note**: Starting with Docker 17.06, stable releases are also pushed to
|
|
> the **edge** and **test** repositories.
|
|
|
|
[Learn about **stable** and **edge** channels](/install/index.md).
|
|
|
|
#### Install Docker CE
|
|
|
|
1. Install the latest version of Docker CE, or go to the next step to install a
|
|
specific version.
|
|
|
|
```bash
|
|
$ sudo dnf install docker-ce
|
|
```
|
|
|
|
If this is the first time you are installing a package from a recently added
|
|
repository, you are prompted to accept the GPG key, and
|
|
the key's fingerprint is shown. Verify that the fingerprint matches
|
|
`060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35` and if so, accept the
|
|
key.
|
|
|
|
> Got multiple Docker repositories?
|
|
>
|
|
> If you have multiple Docker repositories enabled, installing
|
|
> or updating without specifying a version in the `dnf install` or
|
|
> `dnf update` command always installs the highest possible version,
|
|
> which may not be appropriate for your stability needs.
|
|
{:.warning-vanilla}
|
|
|
|
2. On production systems, you should install a specific version of Docker CE
|
|
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.
|
|
|
|
```bash
|
|
$ dnf list docker-ce --showduplicates | sort -r
|
|
|
|
docker-ce.x86_64 {{ site.docker_ce_stable_version }}.0.fc26 docker-ce-stable
|
|
```
|
|
|
|
The contents of the list depend upon which repositories are enabled, and
|
|
are specific to your version of Fedora (indicated by the `.fc26` 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 CE is installed and running. You need to use `sudo` to run Docker
|
|
commands. Continue to
|
|
[Linux postinstall](/install/linux/linux-postinstall.md) to allow
|
|
non-privileged users to run Docker commands and for other optional configuration
|
|
steps.
|
|
|
|
#### Upgrade Docker CE
|
|
|
|
To upgrade Docker CE, 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 need to download
|
|
a new file each time you want to upgrade Docker CE.
|
|
|
|
1. Go to [{{ download-url-base }}/]({{ download-url-base }}/) and choose your
|
|
version of Fedora. Go to `x86_64/stable/Packages/`
|
|
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 above URL to `edge`.
|
|
|
|
2. Install Docker CE, 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](/install/linux/linux-postinstall.md) to allow
|
|
non-privileged users to run Docker commands and for other optional configuration
|
|
steps.
|
|
|
|
#### Upgrade Docker CE
|
|
|
|
To upgrade Docker CE, 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.
|
|
|
|
{% include install-script.md %}
|
|
|
|
## Uninstall Docker CE
|
|
|
|
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.
