###### Procedure

1. Run `apt udpate`

2. Install the following:

        apt install ca-certificates curl

3. Create the keyrings directory with correct permissions:

        install -m 0755 -d /etc/apt/keyrings

4. Save the current key from Docker:

        curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc

5.  Allow everybody to read the `docker.asc` key:

        chmod a+r /etc/apt/keyrings/docker.asc

6. Add the official Docker repository to apt:

        echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

7. Run `apt update` again

8. Install the required Docker packages:

        apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

9. Test that Docker is installed via `docker --version`

10. Test the Docker `hello-world` image:

        docker run hello-world

###### Administration

1. Create a volume for Portainer:

        docker volume create portainer_data

2. Install Portainer:

        docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:2.20.3

    **Note:** The version number `2.20.3` is current at the time of writing but may change in the future

3. Connect to Portainer's web interface by visiting port 9443 in the address bar, e.g. <https://debian-host:9443/>

###### Extras

1. If installing a Microsoft SQL Server for Linux container running Ubuntu, create a volume that maps to `/var/opt/mssql/data` in the container. The databases you create will persist across recreating or duplicating/editing. No additional configuration is needed.
