Every app in this guide, [Jellyfin](/serveex/media/jellyfin), [Vaultwarden](/serveex/apps/vaultwarden), [Immich](/serveex/cloud/immich), to name a few, comes with its own list of dependencies, its own version of Python or Node, its own quirks. Installing all of that directly on Debian works for a while, until two apps want a different version of the same library, or removing one leaves files scattered across the system with no clean way back.

A **container** sidesteps the problem: it packages an app together with everything it needs to run, isolated from the rest of the system and from every other container. Starting one doesn't touch Debian's own packages, and removing it is a single command that leaves nothing behind. It's not a virtual machine either, there's no second operating system to boot or resources to pre-allocate: a container shares the host's kernel and starts in about a second, using only the RAM and CPU the app inside it actually needs.

**Docker** is the tool that builds, starts and manages these containers. Point it at an *image*, a ready-made snapshot of an app maintained by its developers, and it downloads it and runs it in one command. The rest of Serveex is built entirely on it: every app from here on is one Docker container, or a handful of them working together.

## Install Docker
::steps{level="3"}
### Add the Docker repository and GPG key

```bash [Terminal]
# 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/debian/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/debian   $(. /etc/os-release && echo "$VERSION_CODENAME") stable" |   sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
```

### Install the packages

```bash [Terminal]
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```

### Done !

**More options:** [Install Docker for Debian 13](https://docs.docker.com/engine/install/debian/)

::note

From here on, we assume the stacks are installed in the `/srv/docker` folder, created using the command:
```bash [Terminal]
sudo mkdir /srv/docker
```
::

## Install [Dockge](https://github.com/louislam/dockge) to manage and deploy containers
[Dockge](https://github.com/louislam/dockge) is a web tool to create, configure, launch, and manage Docker containers. It's a simple, intuitive interface that’s lighter and easier for beginners than using the CLI or Portainer.

### Configuration

::file-tree
---
label: File structure we will create
tree:
  /:
    - srv:
      - docker:
        - dockge:
          - compose.yml
---
::

::steps{level="4"}
#### Create the stack folder

```bash [Terminal]
cd /srv/docker
sudo mkdir dockge
```

#### Create the compose file

```bash [Terminal]
cd /srv/docker/dockge
sudo nano compose.yml
```
Paste the following:

```yaml [compose.yaml]
---
services:
  dockge:
    image: louislam/dockge:1
    restart: unless-stopped
    container_name: dockge
    ports:
      - 3555:5001 # LAN-accessible port will be 3555

    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /srv/docker/dockge/data:/app/data
      - /srv/docker:/srv/docker
    environment:
      - DOCKGE_STACKS_DIR=/srv/docker
```

Press :kbd{value="Ctrl+O"}, then :kbd{value="Enter"} to save, and :kbd{value="Ctrl+X"} to exit.

#### Launch the container

```bash [Terminal]
cd /srv/docker/dockge
sudo docker compose up -d
```

Then go to `http://yourserverip:3555` in your browser to access the login page.

#### Done !

And there you go! Docker and a tool to easily manage your containers are ready!

## [Watchtower](https://watchtower.nickfedor.com/), to auto-update containers
Watchtower is a container that checks for updates and pulls new images automatically, just by adding a label in your containers’ `compose.yml` files.

### Configuration

::steps{level="4"}
#### Create the stack

- Open Dockge in your browser
- Click `compose`
- Name the stack `watchtower`
- Paste the config below into the default config area in Dockge

```yaml [compose.yaml]
---
services:
  watchtower:
    container_name: watchtower
    image: ghcr.io/nicholas-fedor/watchtower:latest
    restart: unless-stopped
    env_file:
      - .env
    environment:
      - TZ=Europe/Paris
      - WATCHTOWER_SCHEDULE=${SCHEDULE}
      - WATCHTOWER_LABEL_ENABLE=true
      - WATCHTOWER_CLEANUP=true
      - WATCHTOWER_REMOVE_VOLUMES=true
      # Discord notifications - uncomment if used
      #- WATCHTOWER_NOTIFICATIONS=slack
      #- WATCHTOWER_NOTIFICATION_SLACK_IDENTIFIER=Watchtower
      #- WATCHTOWER_NOTIFICATION_SLACK_HOOK_URL=${WH_URL}
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
```

#### Set your environment variables

Fill in the `.env` section in Dockge with the following:

```properties [.env]
SCHEDULE=
WH_URL=
```

| Property       | Value                                                              | Examples                                     |
|----------------|--------------------------------------------------------------------|----------------------------------------------|
| `SCHEDULE`     | Cron format                                                        | `0 0 6 * * *` (every day at 6 AM)            |
| `WH_URL`       | Your Discord webhook URL - append `/slack` at the end              | `https://yourdiscordserver/webhook/slack`   |

#### Enable Watchtower on other containers

To have Watchtower monitor your other containers, add this to their `compose.yml`:

```yaml [compose.yaml]
---
labels:
  - com.centurylinklabs.watchtower.enable=true
```

Then restart the modified stacks.

#### Done !
::

And that's it! You now have a solid base to start deploying the services you want!
