 ### Permanent storage
 Usually you want to keep your FHEM setup after a container was destroyed (or re-build) so it is a good idea to provide an external directory on your Docker host to keep that data:

+Starting with Docker image version 5.1.x, you can control every setting via an environment variable provided by the Docker host. This means there is no need to edit any configuration files manually. All environment variables starting with the common prefix "CONFIG_" are evaluated and added to the configuration file.
+
+To enable SSL for communication with FHEMweb, add an environment variable CONFIG_connections_0_ssl=true. If your container running FHEM is named differently, use the environment variable CONFIG_connections_0_server='fhem.docker.local'. To use another TCP port for communication with FHEM, set the environment variable CONFIG_connections_0_port='8088'.

+The settings for Alexa can also be changed. Here are some examples:
+
+`CONFIG_alexa_port=4000`
+`CONFIG_alexa_name=myAlexaSkill`
+`CONFIG_alexa_ssl=true`
+Additionally, the SSH proxy settings can be changed if needed:
