Add missing environment variable bindings for --port and --verbose.
Add missing environment variable bindings for --port and --verbose. Also sort the environment variable bindings in the same order as the flags bindings so that it's easier to track if one of both is missing.
Complete bindings are important as we start the menshen docker container without any flags and configure it completely by env vars. For debugging during deployment it's nice to have the option to set MENSHEN_VERBOSE
as well.
