8.2. 更新日志转发自定义资源

OpenShift Container Platform Log Forward API 已从 OpenShift Container Platform 4.6 中的技术预览提升为正式发布。GA 发行版本包含一些改进和增强，需要您更改 ClusterLogging 自定义资源（CR），并将 LogForwarding 自定义资源（CR）替换为 ClusterLogForwarder CR。

OpenShift Container Platform 4.6 中的 ClusterLogForwarder 实例示例

apiVersion: logging.openshift.io/v1
kind: ClusterLogForwarder
metadata:
  name: instance
  namespace: openshift-logging
....
spec:
  outputs:
  - url: http://remote.elasticsearch.com:9200
    name: elasticsearch
    type: elasticsearch
  - url: tls://fluentdserver.example.com:24224
    name: fluentd
    type: fluentdForward
    secret:
      name: fluentdserver
  pipelines:
  - inputRefs:
      - infrastructure
      - application
    name: mylogs
    outputRefs:
     - elasticsearch
  - inputRefs:
      - audit
    name: auditlogs
    outputRefs:
      - fluentd
      - default

流程

要将 4.5 中的 ClusterLogForwarder CR 更新至 ClusterLogForwarding CR 4.6，请进行以下修改：

编辑 ClusterLogging 自定义资源（CR）以删除 logforwardingtechpreview 注解：

ClusterLogging CR 示例

apiVersion: "logging.openshift.io/v1"
kind: "ClusterLogging"
metadata:
  annotations:
    clusterlogging.openshift.io/logforwardingtechpreview: enabled 
  name: "instance"
  namespace: "openshift-logging"
....

apiVersion: "logging.openshift.io/v1"
kind: "ClusterLogging"
metadata:
  annotations:
    clusterlogging.openshift.io/logforwardingtechpreview: enabled


  name: "instance"
  namespace: "openshift-logging"
....

Copy to Clipboard

1: 删除 logforwardingtechpreview 注解。

导出 ClusterLogForwarder CR，为 ClusterLogForwarder 实例创建一个 YAML 文件：

oc get LogForwarding instance -n openshift-logging -o yaml| tee ClusterLogForwarder.yaml

$ oc get LogForwarding instance -n openshift-logging -o yaml| tee ClusterLogForwarder.yaml
