禁用 Istio sidecar 注入作业 Pod

如何解决禁用 Istio sidecar 注入作业 Pod

如何为 Kubernetes Job 禁用 Istio sidecar 注入？

apiVersion: batch/v1beta1
kind: CronJob
Metadata:
  name: pod-restart
spec:
  concurrencyPolicy: Forbid
  schedule: '0 8 * * *'
  jobTemplate:
    Metadata:
      annotations:
        sidecar.istio.io/inject: "false"
    spec:
      backoffLimit: 2
      activeDeadlineseconds: 600
      template:
        spec:
          serviceAccountName: pod-restart
          restartPolicy: Never
          containers:
            - name: kubectl
              image: bitnami/kubectl
              command: ['kubectl','rollout','restart','deployment/myapp']

Sidecar 仍然被注入。

解决方法

注释位置错误。你必须把它放在 pod 模板上。

apiVersion: batch/v1beta1
kind: CronJob
metadata:
spec:
  jobTemplate:
    spec:
      template:
        metadata:
          annotations:
            sidecar.istio.io/inject: "false"

  jobTemplate:
    spec:
      template:
        metadata:
          annotations:
            sidecar.istio.io/inject: "false"
        spec:
          containers:
          - name: hello
            image: busybox
            args:
            - /bin/sh
            - -c
            - date; echo "Hello,World!"
