Standard Output Configuration

You can add a standard output tag to collect the standard output logs of the corresponding containers in a pod. Add the following field to spec:template:metadata:annotations: in the YAML file of the pod to specify the names of the containers whose data is to be collected:

kubernetes.AOM.log.stdout: '["container_name0", "container_name1"]'

The rules are as follows:

  1. If the kubernetes.AOM.log.stdout: field does not exist, the standard output logs of all containers in the pod are collected by default. This rule is compatible with original scenarios.
  2. If this field exists and its value is empty, that is, kubernetes.AOM.log.stdout: '[]', the standard output logs of containers in the pod will not be collected.

Example:

spec:
  replicas: 1
  selector:
    matchLabels:
      app: als729
      version: v1
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: als729
        version: v1
      annotations:
        kubernetes.AOM.log.relabel: '{"key1":"value1","key2":"value2","key3":"value3","key4":"value4","key5":"value5","key6":"value6","key7":"value7","key8":"value8","key9":"value9","key10":"value10","key11":"value11","key12":"value12","key13":"value13","key14":"value14","key15":"value16"}'
        kubernetes.AOM.log.stdout: '["container-0","container_name1"]'
