Testing WMS response get CORS error

[Patrick Brockmann]

I would like to test locally on my laptop the last snapshot of the TDS server and I am struggling with CORS or bad answers from the TDS server when I make requests from my page exposed on my local http server.

I think it could be interesting to explain how to quiclky test a TDS with a simple http server.

Here is what has been made.

I have run the TDS instance with a
docker run -d -p 80:8080 unidata/thredds-docker

Also run a http server from python
python -m http.server 8080

I have from my google chrome brower enable CORS '*' request.

Then from my html file when I make a WMS request I get a 403 error ?
What do I miss ?

   <script>
        $(document).ready(function() {
            var ressource = "http://0.0.0.0/thredds/wms/testAll/2004050412_eta_211.nc?service=WMS&version=1.3.0&request=GetCapabilities";
            $.get({url: ressource,
                       async: false 
                      }, function(xml) {
                        console.log(xml);
             });
        });
    </script>

Solved by using
google-chrome -user-data-dir=/my/dir --disable-web-security

run python http_cors.py 8080
to get a http server.

and docker-compose up thredds-production
to get the TDS.

with a docker-compose.yml as following

version: '3'

services:
  thredds-production:
    image: unidata/thredds-docker:latest
    ports:
      - "80:8080"
      - "443:8443"
      - "8443:8443"
    volumes:
      - /my/path/file1.nc:/usr/local/tomcat/content/thredds/public/testdata/file1.nc
      - /my/path/file2.nc:/usr/local/tomcat/content/thredds/public/testdata/file2.nc
