Hi,
here with @tudorbarascu trying to run the image, but running:

http://localhost:8081/cgi-bin/qgis_mapserv.fcgi?

Shows: the requested URL /cgi-bin/qgis_mapserv.fcgi was not found on this server.

We found the qgis_mapserv.fcgi in /usr/bin cannot find configs pointing to that.

Any hints

i can't solve this problem plz help.

how can i solve this problem?

Hi. Just wondering if there is a 3.16 image I can use for this.

Also I'm assuming I just point desktop 3.16 to the localhost 8081 port to connect right? Thanks!

Problem

Due to the recent crash as described here: kartoza/geosafe#538 ,
we found out that on a GeoJSON layer with big size (something like 60MB in test case), the memory usage rocket into 2GB to process these layers. Moreover, when it crash, apache doesn't release the resources, so it has memory leak.

Proposed Solutions

When processing huge GeoJSON layer like this, we might have to disable multiprocess thread.
Let's say the map client requested 4 tiles in parallel. Usually one QGIS Server instance might take all these request and handle it by forking the process in a different thread/worker. But for this case, it causes these problem:

1. All thread work with a different memory page (not shared), so for 60 MB GeoJSON file in test case, it ends up with 4x2GB memory consumptions.
2. When the thread crash, the memory leak stays there, it's not being cleaned up.
3. all 4 thread will try to access the same resource and race condition happens (because it was not quick enough to process tiles).

So I suggest the following solutions:

1. Gave an option to use a separate apache config file where scaling is handled at the container level (scaling the instance, not apache thread)
2. In this config, we only uses maximum of 1 worker (no race condition will happen in that container)
3. In this config, we will not use keep alive. We want to close the connection and make the worker restart fresh to avoid memory leak.

Is is likely this process will work for QGIS Server 3?

I can set up a PR, if you like. Just wanted to confirm that it will work before I get stuck in...

This image does not work. Tried with the default project, copying my own into the container, and use a volume reference.

Hi Tim,

It seems nginx could be a good alternative to Apache, see
http://osgeo-org.1560.x6.nabble.com/Use-Nginx-to-serve-QGIS-Server-td5175087.html

I write this issue just to share interest, and will try it whenever I can find enough time...

Hi,
we are fiddling with the QGIS-Server 3 container. I have a bunch of database layers (PostGIS), all in EPSG:25832. The projct is in EPSG:25832, too. GetCapabilities lists all layers with their bounding box and tells me that EPSG:25832 is an available CRS for both the project and the individual layers. A GetMap request however returns:
<ServiceExceptionReport version="1.3.0"> <ServiceException code="InvalidCRS">Could not create output CRS</ServiceException></ServiceExceptionReport>

Will not render any font labels using Ubuntu 18.04. Have tried the fc-list fonts that are already installed such as dejavu sans.

Sorry I'm a newsbee in docker but I can't run your docker-qgis-server container.

docker run --name "qgis-server" -p 2222:22 -p 8080:80 -d -t kartoza/docker-qgis-server

and if I change port docker create a container but his statut is exited:

docker ps -a

Problem

I have my compose file setup

postgres:
  image: kartoza/postgis:9.5-2.2
  ports:
    - "35432:5432"
  environment:
    - USERNAME=docker
    - PASS=docker
qgisserver:
  image: kartoza/qgis-server:2.18.10
  hostname: qgis-server
  volumes:
    - ./web:/web
  environment:
    - QGIS_PROJECT_FILE=/web/project/project.qgs
    - PGSERVICEFILE=/web/project/pg_service.conf
  links:
    - postgres:postgres
  ports:
    - "30003:80"

When I log into the qgis-server container I can connect to the Postgres container by using the service file. psql service=gis but when I do a get capabilities on my layer the request generated is not valid.

I then proceed to open the project file and replace my data source with a shapefile and do a get capabilities which returns true.

I think QGIS server is not connecting properly to the Postgres container.

When I try to build the image i get the following error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

Hi,

Thank you very much for your work.

Is it ok to add "Header set Access-Control-Allow-Origin "*" " by default in in the apache conf ?
I can't request my WFS server from a client api like openlayers without CORS.

Thanks in advance

It would be really nice to add WPS functionality in this image:

After switching from kartoza/qgis-server:2.18 to kartoza/qgis-server:3.0.3 I encounter various issues.
Besides #17, the GetMap requests now respond with error code 400:

<ServiceExceptionReport xmlns="http://www.opengis.net/ogc" version="1.3.0">
 <ServiceException code="InvalidCRS">Could not create output CRS</ServiceException>
</ServiceExceptionReport>

This might be caused by some path/config issue, as the log indicates some database access issues(?):

...
[84][12:42:10] Can't open database: unable to open database file
[84][12:42:10] Can't open database: unable to open database file
[84][12:42:10] Can't open database: unable to open database file
[84][12:42:11] Error, could not create output CRS from EPSG

I have run a docker qgis server instance, everything works fine with shapefiles, but when I load layers to Qgis Desktop from PostGis installed in the host and also in a docker container, the getCapabilities are not showing the layers.

I am running an Ubuntu 20.04 LTS host and Qgis Coruña. The containers were created based on the configuration bellow:

Example QGIS Server docker compose

This file will run two QGIS Server instances

QGIS 2.18 LTR - on port 8080 publishing contents of /project

QGIS 3.0 - on port 8081 publishing contents of /project-qgis3

Hello, I want to deploy a QGIS project:
qgis_project.zip

Using this command:

docker run --name "qgis-server" -v $(pwd)/qgis_project/:/project -p 8080:80 -d -t kartoza/qgis-server:3.0.3

But I've get the error:

What I'm doing wrong?

With LTS version I don't have any problem.
