By default no arguments are passed to `docker run` when deploying the container and the `CMD` or `ENTRYPOINT` defined in the `Dockerfile` are executed. You can take advantage of docker ability of overriding the `CMD` or passing parameters to your `ENTRYPOINT` setting `$DOKKU_DOCKERFILE_START_CMD`. Let's say for example you are deploying a base nodejs image, with the following `ENTRYPOINT`:
```
ENTRYPOINT ["node"]
```
You can do:
```
dokku config:set DOKKU_DOCKERFILE_START_CMD="--harmony server.js"
```
To tell docker what to run.
Setting `$DOKKU_DOCKERFILE_CACHE_BUILD` to `true` or `false` will enable or disable docker's image layer cache.
