Pod Labels and Annotations

Pod Annotations

CCE allows you to add annotations to a YAML file to realize some advanced pod functions. The following table describes the annotations you can add.

Table 1 Pod annotations

Annotation	Description	Default Value
kubernetes.AOM.log.stdout	Standard output parameter. If not specified, the standard log output of all containers is reported to AOM. You can collect stdout logs from certain containers or ignore them at all. Example: Collecting none of the stdout logs: kubernetes.AOM.log.stdout: '[]' Collecting stdout logs of container-1 and container-2: kubernetes.AOM.log.stdout: '["container-1","container-2"]'	-
metrics.alpha.kubernetes.io/custom-endpoints	Parameter for reporting AOM monitoring metrics that you specify. For details, see Custom Monitoring <cce_10_0201>.	-

Pod Labels

When you create a workload on the console, the following labels are added to the pod by default. The value of app is the workload name. You can add labels as required.

The pod labels added here will be added to the selector.matchLabels parameter in the workload definition. The following is an example YAML file:

...
spec:
  selector:
    matchLabels:
      app: nginx
      version: v1
  template:
    metadata:
      labels:
        app: nginx
        version: v1
    spec:
      ...
