Logging (Core) - Sprint 214
The Vector config for Loki labels have wrong values for kubernetes_host and kubernetes_namespace_name. The kubernetes_namespace_name = "kubernetes.namespace_name" while it should be kubernetes_namespace_name = "pod_namespace". Following is the Vector config that is generated by CLF.
[sinks.loki_server.labels] kubernetes_container_name = "{{kubernetes.container_name}}" kubernetes_host = "${NODE_NAME}" kubernetes_namespace_name = "{{kubernetes.namespace_name}}" kubernetes_pod_name = "{{kubernetes.pod_name}}" log_type = "{{log_type}}"

Steps to reproduce the issue.
*Install a Loki server.
*Forward logs to the Loki server with Vector as collector.
apiVersion: logging.openshift.io/v1
kind: ClusterLogForwarder
metadata:
name: instance
namespace: openshift-logging
spec:
outputs:
outputs:
- name: loki-server
type: loki
url: http://loki-server.loki-aosqe.svc:3100
pipelines:
- name: to-loki
inputRefs:
- application
- audit
- infrastructure
outputRefs:
- loki-server
*Check the generated Vector config and the log record in Loki.
Vector Loki labels config:
[sinks.loki_server.labels] kubernetes_container_name = "{{kubernetes.container_name}}" kubernetes_host = "${NODE_NAME}" kubernetes_namespace_name = "{{kubernetes.namespace_name}}" kubernetes_pod_name = "{{kubernetes.pod_name}}" log_type = "{{log_type}}"
