Promethous not gathering metrics until added to a existing docker bridge network.

[H T]

Is it mandatory to add Prometheus docker container to an existing bridge network for extracting metrics ?

I Have an existing docker bridge network with few containers and i am trying to extract metrics from them. But prometheus only works when i add it to that existing bridge network

Per-se, there is no such need. This sounds like it may highly depend on
your setup.

Prometheus needs network access to the scrape target. If this is only
possible by using a bridge in your setup, then yes, "Prometheus needs this".

Kind regards,
