[Bug] Inaccessibility of metrics when running in Docker about aptos-core

[rustielin]

Thanks for reporting this issue! A fix is on the way #205

@Krishnacore try pulling the latest changes and see if it fixes it. I was able to repro and fix on my side. You can even confirm that we're listening to the right address by:

docker-compose up

# exec into your docker fullnode
docker container exec -it <container ID> bash

$ apt-get update && apt-get -y install lsof
$ lsof -i -P -n | grep LISTEN
...
aptos-nod   1 root   14u  IPv4 489652      0t0  TCP *:9101 (LISTEN)

The default address for the debug config (of which metrics are a part) can be found here: https://github.com/aptos-labs/aptos-core/blob/main/config/src/config/debug_interface_config.rs#L16-L25, and you can see that it's listening to 0.0.0.0:9091

Yes, my mistake. I misplaced the ports.
By the way, did you think to add to your Dockerfiles something like:
ENV PATH="${PATH}:/opt/aptos/bin"
So you don't have to specify the full path to the binaries in docker-compose?
