</details>### Systemvorrausetzungen

- Docker Compose muss auf dem System installiert werden
- 4GB RAM
- Systemeinstellungen müssen wie folgt angepasst werden

```
sysctl -w vm.max_map_count=262144
```

### Installation mit Docker Compose

**GitHub Repo klonen**

```bash
git clone https://github.com/zammad/zammad-docker-compose.git
```

**Adjust Environment as Needed**

In some cases our default environment is not what a docker-compose user is looking for. See [<span class="doc">Docker Environment Variables</span>](https://docs.zammad.org/en/latest/install/docker-compose/environment.html) for details on which settings can be configured.

<p class="callout info">If you want to use a `<span class="pre">.env</span>` file, you can use the provided `<span class="pre">.env.dist</span>` file and copy it to `<span class="pre">.env</span>`. That way it will be picked up by Docker-Compose automatically and not overwritten during updates.</p>

Zammad runs on port `<span class="pre">8080</span>` by default. If you want to use another port, you can set it via the variable `<span class="pre">NGINX_EXPOSE_PORT</span>`.
