CGI variable "map" fails to validate.

[MrApe]

I'm trying to get the mapserver up and running but get the following error:

msCGILoadMap(): Web application error. CGI variable "map" fails to validate.

Here is my compose file:

version: '3'
services:
  mapserver:
    image: camptocamp/mapserver
    ports:
      - 8081:80
    volumes:
      - $PWD/mapserver/:/etc/mapserver/
    restart: unless-stopped

The local mapserver dir contains the following:

mapserver
├── data
│   └── states_ugl.shp
└── mapserver.map

• mapserver.map is the example file from the map server tutorial.
• states_ugl.shp is the corresponding shapes file.

I changed the SHAPEPATH to use the data-directory:

SHAPEPATH      "data"

mapserver.map

The query used is:

http://localhost:8081/cgi-bin/mapserv?map=/etc/mapserver/mapserver.map

What could be the problem?

Is there a typo in the querystring?

http://localhost:8081/cgi-bin/mapserv?map=/etc/mapserver/mapserve.map

Shouldn't it be http://localhost:8081/cgi-bin/mapserv?map=/etc/mapserver/mapserver.map

Thanks for helping out. It was actually just a type in the issue, not the original query. I double checked and fixed the original post.

Hey Guys,
I am getting similar issue although I exactly followed above steps to spin up the server.

When doing curl

curl -X GET http://localhost:8081/cgi-bin/mapserv?map=/etc/mapserver/mapserver.map

Not sure what's going wrong and how to debug it. Just trying to setup a basic minimalistic version of it.
Any kind of help would be highly appreciated.

[sbrunner]

And what did you get with this URL http://localhost:8081/?map=/etc/mapserver/mapserver.map?

@sbrunner

mapserv(): Web application error. Traditional BROWSE mode requires a TEMPLATE in the WEB section, but none was provided.
This is what I get.

[sbrunner]

MapServer 8 requires a configuration file, did you do that?

@sbrunner : Below is my entire setup:

docker-compose.yaml:

version: '3'
services:
  mapserver:
    image: camptocamp/mapserver
    ports:
      - 8081:80
    volumes:
      - /mapserver/test/:/etc/mapserver/
    restart: unless-stopped

content inside /mapserver/test dir:

mapserver.map file:

    END
  END # States polygon layer ends here
  # End of LAYER DEFINITIONS -------------------------------

END # All map files must come to an end just as all other things must come to...

I'm running it using docker-compose up command.

This is what I see in my terminal:

Is there any other config file that I need to define? Am else I am missing in this minimalistic setup?

Thanks a lot!

@Zia- there is a working Docker file using the camptocamp image at https://github.com/geographika/getting-started-with-mapserver/blob/main/workshop/exercises/docker-compose.yml
Docs at https://geographika.github.io/getting-started-with-mapserver/

It also has a config file https://github.com/geographika/getting-started-with-mapserver/blob/main/workshop/exercises/mapfiles/mapserver.conf referenced in the docker-compose file:

    environment:
      MAPSERVER_CONFIG_FILE: "/etc/mapserver/mapserver.conf"

Hello all,

I have similar issue, but in my case, I have working configuration based on camptocamp/mapserver:8.0, but when I try to update to version 8.2 or even 8.4. Mapserver will stop working with error "Web application error. CGI variable "map" fails to validate.". The only thing I'm changing is image version, nothing else. Any idea what could change between version 8.0 and 8.2?

Thanks
