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.

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.

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"
