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

[Seth G]

Hi Rob,

You could try uncommenting the MS_MAP_PATTERN in the mapserver.conf [1] file on your Docker image to see if that has an effect. 

You should also see a log file named /tmp/init_env that lists all the environment variables used by Apache (including MS_MAP_PATTERN), similar to below:

export "MAPSERVER_CONFIG_FILE=/etc/mapserver/mapfiles/mapserver.conf"
export "MAPSERVER_CATCH_SEGV=1"
export "HOSTNAME=mapserver"
export "APACHE_CONFDIR=/etc/apache2"
export "BUSY_TIMEOUT=300"
export "MS_ERRORFILE=mapserver-8.0.log"
export "PWD=/etc/mapserver"
export "IO_TIMEOUT=40"
export "HOME=/root"
export "APACHE_LOG_DIR=/var/log/apache2"
export "MIN_PROCESSES=1"
export "APACHE_PID_FILE=/tmp/apache2/apache2.pid"
export "MS_MAP_PATTERN=^\/etc\/mapserver\/([^\.][-_A-Za-z0-9\.]+\/{1})*([-_A-Za-z0-9\.]+\.map)$"
