Hi All
I wanted to use promtail as a sidecar with nginx container.
I have created a deployment that does not seem to work.
Can anyone please help me correct the Yaml script?

PS C:\Windows\system32> notepad .\config.yaml
Loki and Grafana is running and In grafana dashboard i can see that there are no logs as promtail is not able to push any logs to loki.
Please help me in configuring the manifest to resolve the issue
