Hitting https://pavics.ouranos.ca/geoserver/wfs?request=GetCapabilities&version=1.1.0

Before fix (wrong scheme and wrong port):

<ows:Operation name="GetCapabilities">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:href="http://pavics.ouranos.ca:80/geoserver/wfs"/>
<ows:Post xlink:href="http://pavics.ouranos.ca:80/geoserver/wfs"/>
</ows:HTTP>
</ows:DCP>

After fix:

<ows:Operation name="GetCapabilities">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:href="https://pavics.ouranos.ca:443/geoserver/wfs"/>
<ows:Post xlink:href="https://pavics.ouranos.ca:443/geoserver/wfs"/>
</ows:HTTP>
</ows:DCP>

This config automate manual step to set proxy base url in Geoserver UI https://docs.geoserver.org/2.9.3/user/configuration/globalsettings.html#proxy-base-url

I had to override the docker image entrypoint to edit the server.xml on the fly before starting Geoserver (Tomcat) since setting Java proxy config did not seem to work (see first commit).

Related to Ouranosinc/raven#297.

Edit:

  • Added "I had to override the docker image entrypoint to edit the server.xml on the fly before starting Geoserver (Tomcat) since setting Java proxy config did not seem to work (see first commit)."

As suggested here
https://serverfault.com/questions/177273/set-up-http-proxy-for-tomcat-web-server
and here https://memorynotfound.com/configure-http-proxy-settings-java/
using setenv.sh trick from
https://github.com/kartoza/docker-geoserver/tree/2.9.4#setting-tomcat-properties

Trying to fixing this problem:

Hitting directly geoserver http://pavics.ouranos.ca:8087/geoserver/wfs?request=GetCapabilities&version=1.1.0 (only works inside Ouranos firewall), I am getting proper
```
<ows:Operation name="GetCapabilities">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:href="http://pavics.ouranos.ca:8087/geoserver/wfs"/>
<ows:Post xlink:href="http://pavics.ouranos.ca:8087/geoserver/wfs"/>
</ows:HTTP>
</ows:DCP>
```

Behind Nginx proxy https://pavics.ouranos.ca/geoserver/wfs?request=GetCapabilities&version=1.1.0, we end up with the wrong http protocol and the wrong port
```
<ows:Operation name="GetCapabilities">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:href="http://pavics.ouranos.ca:80/geoserver/wfs"/>

Adding @matprov as well.

If CRIM instances have autodeploy enabled, there is nothing to do on your side, you'll just get it automatically.

Sorry maybe I need to explain in simple terms what I did for everyone else as well.

501d900 
Restore this fix:
#106, adapt to new
entrypoint.

Tested setting env var `HTTPS_PROXY_NAME: ${PAVICS_FQDN_PUBLIC}`, as in
https://github.com/kartoza/docker-geoserver/blob/b3239c32da009dca57e15ffdb5c3f3a465184466/scripts/start.sh#L186-L188,
did not work.

Test:
```
$ curl --silent "https://lvupavicsmaster.ouranos.ca/geoserver/wfs?request=GetCapabilities&version=1.1.0" | xmllint --format - |grep lvupavicsmaster
