Possibility to collect (tail) logs from stdout/stderr, port?

The current static_config uses path (log files) https://grafana.com/docs/loki/latest/clients/promtail/configuration/#static_configs that for symlinks is not working as expected.

Using: PLG Stack
Grafana: 7.4.0
Loki: 2.1.0
Promtail: 2.1.0

Describe the solution you'd like

• Promtail being able to tail logs from: path file logs - symlinks, port, stdout, stderr of a pod/container in RHEL OpenSHift Container > 3.9 from a namespace.

Describe alternatives you've considered

• At least being able to tail path file logs - symlinks.
