 **Warning:** if you're using the Alpine variant, there is currently [an outstanding bug (Alpine Linux bug #5700) with the `erlang-hipe` package](https://bugs.alpinelinux.org/issues/5700) which prevents HiPE from working in Alpine Linux. See [docker-library/rabbitmq#151](https://github.com/docker-library/rabbitmq/issues/151) for more discussion.

 It is therefore important to take that startup delay into consideration when configuring health checks, automated clustering etc.
 
+### Additional Configuration
+
+If additional configuration is required, it is recommended to use the `RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS` environment variable, whose syntax is described [in section 7.8 ("Configuring an Application") of the Erlang OTP Design Principles User's Guide](http://erlang.org/doc/design_principles/applications.html#id81887) (the appropriate value for `-ApplName` is `-rabbit`).
+
+For example, configuring [`log_levels`](https://www.rabbitmq.com/configure.html#config-items) would look something like `-e RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS="-rabbit log_levels [{connection,error}]"`.
+
+Additional configuration keys would be specified as a list. For example, configuring both [`log_levels`](https://www.rabbitmq.com/configure.html#config-items) and [`auth_backends`](https://www.rabbitmq.com/ldap.html#overview) would look something like `-e RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS="-rabbit log_levels [{connection,error}] auth_backends [rabbit_auth_backend_ldap]"`.
