Loki Log Querying

Setup

Loki does not have an HTTPRoute on the internal ingress gateway, so it requires port-forward access (unlike Prometheus and Grafana which are available via DNS).

kubectl --context <cluster> port-forward -n monitoring svc/loki-headless 3100:3100 &
export LOKI_URL=http://localhost:3100

Clusters: dev, integration, live

Why port-forward? Loki's gateway component is disabled (replicas: 0) and no HTTPRoute exists for it on the internal ingress gateway. For other services that do have HTTPRoutes (Prometheus, Grafana, Alertmanager), prefer using the internal DNS URLs instead -- see the k8s skill for the full URL table.
