 A few things to note about this command:
- * `$PWD/data` : The docker host directory in Windows operating system must be lowercase.`$PWD/data` provides you with the specified directory, for example: `E:/data`.

+ * The data, metadata, and configuration are persisted on Docker volumes in order to not start "fresh" every

+ * For Docker on Windows make sure to configure it to use Linux containers
