Rendertron needs to run behind an HTTP proxy

I have a scenario that Rendertron services need to run behind an HTTP proxy. I am not able to find the configuration that enables this setup.

Is it possible to achieve that?

It seems there is no straight way to achieve it right now. What you can possible do is to change its source code until there is a new version of Rendertron that supports running it behind an HTTP proxy.

You can add an additional argument when launching the headless browser puppeteer as below, in src/rendertron.ts

And when starting Rendertron, be sure to pass in the environment variable RENDERTRON_HTTP_RPOXY. See this open GitHub pull request for details.

It is also possible to specify puppeteer arguments in config, see another open GitHub pull request.
