The Docker image only needs the port 8080 to be exposed
```
-$ docker run --rm -p 8080 apache/sling:snapshot
+$ docker run --rm -p 8080:8080 apache/sling:snapshot
```
By default the image launches the `oak_tar` aggregate, which uses local persistence. The aggregate to launch can be selected by passing an additional argument to the image, e.g.:
```
-$ docker run --rm -p 8080 apache/sling:snapshot oak_mongo
+$ docker run --rm -p 8080:8080 apache/sling:snapshot oak_mongo
```
Currently only the `oak_tar` and `oak_mongo` aggregates are supported.
