Hello!

I was testing Fluent Bit earlier this week, and struggled with getting the new YAML configuration file to work with Docker.
Just mounting the volume doesn't work, the default fluent-bit.conf in the image takes precedence over the YAML file, which took me a while to troubleshoot.

For example:

# fluent-bit.yaml
pipeline:
  inputs:
    - name: dummy
      dummy: '{"from": "yaml"}'

  outputs:
    - name: stdout

Running docker run -ti -v ./fluent-bit.yaml:/fluent-bit/etc/fluent-bit.yaml cr.fluentbit.io/fluent/fluent-bit does not load the YAML file.

Mounting the .conf file works though.
Maybe this will help those who tried the same thing as I did.

Let me know if you think anything needs changing or if you believe there is a better way to do this. Thanks!
