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

[Rob Dennett]

Not sure how uncommenting something in the conf from camptocamp would help when we're actually setting MS_MAP_PATTERN in our Dockerfile which relies on the camptocamp one as a base image.  I created a github issue for this as well and they advised running

Docker run <image> env | grep MS_

And I see MS_MAP_PATTERN defined there along with MS_MAPFILE set to what I am expecting.  Wouldn't this prove that the environment variables are set correctly?

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)$"

We're using the camptocamp MapServer image and I just tried changing the base image from 7.6 to 8.0, i.e.
FROM camptocamp/mapserver:7.6

To

FROM camptocamp/mapserver:8.0

in our own Dockerfile and when I try to deploy, We're seeing

"msCGILoadMap(): Web application error.  Required configuration value MS_MAP_PATTERN not set."

on some endpoints (the ones ending in .map)

The camptocamp image contains

ENV MS_MAP_PATTERN=^\\/etc\\/mapserver\\/([^\\.][-_A-Za-z0-9\\.]+\\/{1})*([-_A-Za-z0-9\\.]+\\.map)$

(https://github.com/camptocamp/docker-mapserver/blob/8.0.0/Dockerfile#L85)

and our own overwrites this env var anyway, along with MS_MAPFILE

These haven't changed and they work fine as long as the base image is 7.6. The changelog mentions MS_MAPFILE, but as mentioned, we do define it.

(https://github.com/camptocamp/docker-mapserver/blob/8.0.0/README.md#changelog)

Any idea what might be happening?
