[MapServer-users] Getting msCGILoadMap(): Web application error. Required configuration value MS_MAP_PATTERN not set.

[Seth G]

Try setting MAPSERVER_CONFIG_FILE to point to a mapserver.conf in your own Dockerfile and setting MS_MAP_PATTERN in this config file. 

Without seeing your custom Dockerfile it is hard to know what could be removing an environment variable - it is simpler to control things with a config file.

If you check the /tmp/init_env file you should see the variables that are passed to the Apache environment (which is different from the system environment). If you override the default CMD ["/usr/local/bin/start-server"] then these env variables won't be set.
