# Docker

We also provide a dockerized version of the databus client in our [DockerHub repository](https://hub.docker.com/r/dbpedia/databus-client).

You can pass all the variables as Environment Variables (**-e**), that are shown in [Usage](/databus/download-client/usage.md#databus-client-parameters) (except `target`), but you have to write the Environment Variables in Capital Letters.

### Requirements

* **Docker:** `^3.5`

### Installation

Pull a docker image of our [DockerHub repository](https://hub.docker.com/r/dbpedia/databus-client).

```
docker pull dbpedia/databus-client:latest
```
