[FIXED] How to execute OpenTest thru Apache reverse proxy along with other applications

Issue

First some context

• We have an Ubuntu Server 18.04 LTS server running on Azure
• Our company security policies only allows for ports 80 and 443 to be accessed thru HTTP/HTTPS
• Any applications such as Jenkins or NodeJS ones running on other ports should use a reverse proxy thru Apache
• The same server already has Jenkins running on port 8080 and Jenkins itself can be configured to run using what they call a "--path" parameter which makes it accessible thru URL http://localhost:8080/jenkins, hence reverse proxy is pretty straight forward to configure as anything going to "/jenkins" can just be pass to http://localhost:8080/jenkins, current Apache config (which is working for Jenkins) as follows:

        # Jenkins
        ProxyPass         /jenkins  http://localhost:8080/jenkins nocanon
        ProxyPassReverse  /jenkins  http://localhost:8080/jenkins
        ProxyRequests     Off
        AllowEncodedSlashes NoDecode
        <Proxy http://localhost:8080/jenkins*>
           Order deny,allow
           Allow from all
        </Proxy>

The problem we are facing

So, for running OpenTest, we have to install it as a npm package which can then be executed by running opentest server command, it will start the application on port 3000 by default http://localhost:3000 but it is possible to change the preferred port as well thru configuration https://getopentest.org/reference/configuration.html#server-configuration

The problem is that we need to re-route anything, let's say going to "/opentest" to the opentest server app but that doesn't work for all static assets, api urls, etc... since the app is just running on port 3000 http://localhost:3000 but doesn't seems to have something like the Jenkins' "--path", so we can't just mimic the same reverse proxy we have for Jenkins; the idea would be to have opentest in path "/opentest", something like http://localhost:3000/opentest.

We were not able to find any OpenTest configuration that allows me to do something like http://localhost:3000/opentest and we are new to pm2 so we can't tell if it is possible to use pm2 to to run the OpenTest application in a "path" or some sort of "local known application domain" which we could use to re-route the reverse proxy to.

Any thoughts, ideas, workarounds or solutions are welcome; we might be taking the wrong approach here so we would also appreciate any insights in that regard.

Thanks!

Solution

Starting with version 1.2.0, you can use the urlPrefix configuration parameter in server.yaml to accomplish this:

#...

urlPrefix: /opentest
