I haven’t tested this yet, but changing [line 289 in the current launcher](https://github.com/discourse/discourse_docker/blob/5701c085f4773dce8943ec145a0f808ac5fbef3a/launcher#L289) script to the following should work.

```
$docker_path run $restart_policy "${env[@]}" -h "`hostname`-$config" -m="4g" -e DOCKER_HOST_IP=$docker_ip --name $config -t --cidfile $cidfile $ports \

```

I’ve added `-m="4g"` in order to limit the container to 4GB of memory.

> -m=“”: Memory limit (format: , where unit = b, k, m or g)
