Grafana Loki not scrapping Kubernetes logs with default Helm chart

Grafana Loki
1

Hello. I have installed Grafana Loki in my K3s Kubernetes cluster, using the official helm chart, but I don´t have any logs, besides the ones of self-monitoring.

It´s not even detecting any container in Loki query interface (only Loki itself).

Do I need to do any configuration or something for it to start scrapping? I suppose the Helm chart should handle that out of the box.

Here are the values I used to install Grafana Loki (I am using Grafana Agent, without the Operator)

   loki:
      commonConfig:
        replication_factor: 1
      storage:
        type: "filesystem"
      compactor:
        retention_enabled: true
      limits_config:
        retention_period: 15d
      auth_enabled: false
      rulerConfig:
        storage:
          type: local
    singleBinary:
      replicas: 1
      persistence:
        enabled: true
        size: 50Gi
    gateway:
      enabled: false
    monitoring:
      selfMonitoring:
        enabled: true
        grafanaAgent:
          installOperator: false
      lokiCanary:
        enabled: false
    resources:
      requests:
        cpu: 10m
        memory: 128Mi
      limits:
        cpu: 100m
        memory: 256Mi
    test:
      enabled: false

I couldn´t find any relevant logs on the loki container

Having the exact same issue, how did you solve this? Don’t want to add a PodLogs resource for each deployment.
