# docker
This example is using docker in combination with [solve-groups](https://pixi.sh/latest/configuration/#the-environments-table).
The solve-groups ensure that the `default` environment (where the tests are run) is using *exactly* the same versions of the dependencies as the `prod` environment.
In the docker container, we only copy the `prod` environment into the final layer, so the `default` environment and all its dependencies are not included in the final image.
Also, `pixi` itself is not included in the final image and we activate the environment using `pixi -e prod shell-hook`.
## Usage
To build and run the docker container you require [`docker`](https://docs.docker.com/engine/install/)
When you have `docker` use the following commands:
```shell
docker build -t pixi-docker .
docker run -p 8000:8000 pixi-docker
```
