Fedora

Set up the DNF repository

Before you install Docker Engine 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.

Install the dnf-plugins-core package (which provides the commands to manage your dnf repositories) and set up the repository:

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

Install Docker Engine

Install Docker Engine, containerd, and Docker Compose:
```
sudo dnf install -y \
 containerd.io \
 docker-buildx-plugin \
 docker-ce \
 docker-ce-cli \
 docker-compose \
 docker-compose-plugin
```
If prompted to accept the GPG key, verify that the fingerprint matches
060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35, and if so, accept it.
This command installs Docker, but it doesn’t start Docker. It also creates a docker group, however, it doesn’t add any users to the group by default.

Start Docker:

sudo systemctl enable docker
sudo systemctl start docker

Add user to docker group:
```
sudo usermod -aG docker ${USER}
```
Verify that the Docker Engine installation is successful by running the hello-world image:
```
sudo docker run hello-world
```
This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.
You have now successfully installed and started Docker Engine.
Once Docker is installed, setting up Portainer is straightforward. You can choose between the Portainer Community Edition (CE) or the Business Edition (BE). Simply copy and paste the command from the quick install guide portainer to get started.

Uninstall Docker Engine

Stop Docker:

sudo systemctl disable docker
sudo systemctl stop docker

Remove user from the docker group:
```
sudo deluser ${USER} docker
```

Uninstall the Docker Engine, CLI, containerd, and Docker Compose packages:

sudo dnf remove -y \
 docker-ce-rootless-extras \
 containerd.io \
 docker-buildx-plugin \
 docker-ce \
 docker-ce-cli \
 docker-compose \
 docker-compose-plugin

Images, containers, volumes, or custom configuration files on your host aren’t automatically removed. To delete all images, containers, and volumes.
You have to delete any edited configuration files manually:
```
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
```
You have now successfully uninstalled Docker Engine.

Ubuntu

info

Official Docker documentation for Ubuntu

Set up the APT repository

Before you install Docker Engine 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:

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

info

If you use an Ubuntu derivative distro, such as Linux Mint, you may need to use UBUNTU_CODENAME instead of VERSION_CODENAME.

Install Docker Engine

Install Docker Engine, containerd, and Docker Compose:
```
sudo apt-get -y install \
 containerd.io \
 docker-buildx-plugin \
 docker-ce \
 docker-ce-cli \
 docker-compose \
 docker-compose-plugin
```
This command installs Docker, but it doesn’t start Docker. It also creates a docker group, however, it doesn’t add any users to the group by default.

Start Docker:

sudo systemctl enable docker
sudo systemctl start docker

Add user to docker group:
```
sudo usermod -aG docker ${USER}
```
Verify that the Docker Engine installation is successful by running the hello-world image:
```
sudo docker run hello-world
```
This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.
You have now successfully installed and started Docker Engine.
Once Docker is installed, setting up Portainer is straightforward. You can choose between the Portainer Community Edition (CE) or the Business Edition (BE). Simply copy and paste the command from the quick install guide portainer to get started.

Uninstall Docker Engine

Stop Docker:

sudo systemctl disable docker
sudo systemctl stop docker

Remove user from the docker group:
```
sudo deluser ${USER} docker
```

Uninstall the Docker Engine, CLI, containerd, and Docker Compose packages:

sudo apt-get purge -y \
 containerd.io \
 docker-buildx-plugin \
 docker-ce \
 docker-ce-cli \
 docker-ce-rootless-extras \
 docker-compose \
 docker-compose-plugin

Images, containers, volumes, or custom configuration files on your host aren’t automatically removed. To delete all images, containers, and volumes.
You have to delete any edited configuration files manually:
```
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
```
You have now successfully uninstalled Docker Engine.

Quick install guide Portainer

Once Docker is installed, setting up Portainer is straightforward. You can choose between the Portainer Community Edition (CE) or the Business Edition (BE). Simply copy and paste the command from the quick install guide portainer into your terminal and hit enter. Docker will create the necessary network and pull the Portainer container from Docker Hub.

After that, open your browser and navigate to the IP address of your local machine where Docker is installed. For example, if your server’s IP address is 192.168.10.10, go to http://192.168.10.10:9000 or https://192.168.10.10:9443 to access the Portainer GUI. Follow the instructions there to complete the installation of Portainer.

Congratulations, you have now installed Portainer. From now on, you will use Portainer to start new Docker projects.

info

Note: If you use one of Homelab-Alpha’s Docker run commands or Docker Compose files, persistent volumes are utilized. You can find your data from your containers in the root directory named docker/. For example, all data from the Portainer container is stored in docker/portainer.
