loganmc10 / openshift-loki-installer

Usage

The target cluster requires NooBaa (ODF Multicloud Object Gateway).

loki_size defaults to 1x.small. See https://docs.openshift.com/container-platform/latest/logging/cluster-logging-loki.html#deployment-sizing_cluster-logging-loki for possible options.

export KUBECONFIG=~/path/to/kubeconfig
ansible-playbook loki-playbook.yaml -e "loki_size=1x.extra-small"

Optional arguments:

-e "auditing=true"
-e "remote_logging=true"

Remote Logging

When remote_logging is enabled, the playbook writes a file with a Secret named <loki_route>-secret.yaml to the playbook directory.

This Secret can be applied to the remote cluster, and then used for log forwarding, for example:

apiVersion: logging.openshift.io/v1
kind: ClusterLogForwarder
metadata:
  name: instance
  namespace: openshift-logging
spec:
  outputs:
    - name: loki-app
      type: loki
      url: https://logging-loki-openshift-logging.apps.cluster.example.com/api/logs/v1/application
      secret:
        name: remote-logging-secret
...
  pipelines:
    - name: send-app-logs
      inputRefs:
        - application
      outputRefs:
        - loki-app
      labels:
        clustername: <cluster_name>
...
