service telemetry metrics only binding to localhost

What happened?

Description

In version 0.123.0 despite configuring the collector to bind to 0.0.0.0:8888 for metrics it only binds to localhost:8888. This is causing me issues when I try to navigate to this as a running container on my AWS account. The same config works fine in version 0.121.1

Steps to Reproduce

Add telemetry metrics to the service over port 8888:

...
service:
  telemetry:
    metrics:
      address: 0.0.0.0:8888
....

Expected Result

The collector should bind to all addresses on port 8888:

Actual Result

Collector version

0.123.0

Environment information

Environment

AWS ECS - but I was able to reproduce this locally as a regular docker container

The address field is deprecated now: open-telemetry/opentelemetry-collector#12756.

Also, this should go in the core repo https://github.com/open-telemetry/opentelemetry-collector.

thank you for pointing that out. From looking at the code it seems this was replaced with this?

...
service:
  telemetry:
    metrics:
      readers:
        - pull:
          exporter:
            prometheus:
              host: 0.0.0.0
              port: 8888
...

on edit: For future people searching the answer is yes. Looks like that is pointed out in the documentation here: https://opentelemetry.io/docs/collector/internal-telemetry/#configure-internal-metrics
