Additionally, familiarity with [Docker](https://www.docker.com/get-started) is recommended.

### Docker memory requirements
-The default `docker-compose.yml` launches eight containers: Zookeeper, PostgreSQL, and six Druid containers. Each Druid service is configured to use up to 7 GB of memory (6 GB direct memory and 1 GB heap). However, the Quickstart will not use all the available memory.
+The default `docker-compose.yml` launches eight containers: Zookeeper, PostgreSQL, and six Druid containers based upon the [micro quickstart configuration](../operations/single-server.html#micro-quickstart-4-cpu-16gib-ram).
+Each Druid service is configured to use up to 7 GiB of memory (6 GiB direct memory and 1 GiB heap). However, the quickstart will not use all the available memory.
-Docker needs at least 6 GiB of memory available for the Druid cluster. For Docker Desktop on Mac OS, adjust the memory settings in the [Docker Desktop preferences](https://docs.docker.com/desktop/mac/). If you experience a crash with a 137 error code you likely don't have enough memory allocated to Docker.

+You can modify the value of `DRUID_SINGLE_NODE_CONF` in the Docker [`environment`](#environment-file) to use different single-server mode. For example to use the nano quickstart: `DRUID_SINGLE_NODE_CONF=nano-quickstart`.
