metrics-addr should be 0.0.0.0:9323 for a dockerized prometheus to reach it #21632
Description
Is this a docs issue?
- My issue is about the documentation content or website
Type of issue
Information is incorrect
Description
The documentation states you should configure /etc/docker/daemon.json to listen on the loopback interface as such:
{
"metrics-addr": "127.0.0.1:9323"
}but then states Prometheus can be run in a container, which would resolve host.docker.internal to an address on Dockers network, something like 172.17.0.1. Even though the address leads to the same host as the daemon, there is nothing listening to port 9323 for that specific address.

Suggestion
To make the guide applicable to a larger majority, the suggested configuration should instead be:
{
"metrics-addr": "0.0.0.0:9323"
}
