Reverse Proxy non-containerized application

[dcampillo]

Hi,

I am supper happy with NPM, but I am stuck with proxying application which are not in Docker:

• I have some custom Python/Flask web app that are not containerized and run locally on the same server where NPM seats, and I can't figure out how to proxy a "localhost" app.
• Seems that for NPM, localhost or 127.0.0.1 refer to itself, which to me is correct.
• Using UFW, I can't reach out to the external server ip, unless I open a port, which is not wanted.

Any clue?

THANKS,

David

Well, I found the issue, which is quite obvious:

• In UFW, I have allowed the traffic only from the DOCKER networks where my container seats

Works!
