Description

Each container should define a readinessProbe. This rule flags containers that do not have the readinessProbe attribute set (excludes resources of kind Job and CronJob). A configured readinessProbe lets the kubelet determine when a pod is ready to receive traffic.

Compliant Code Examples

apiVersion: v1
kind: Pod
metadata:
  name: goproxy
  labels:
    app: goproxy
spec:
  containers:
  - name: goproxy
    image: k8s.gcr.io/goproxy:0.1
    ports:
    - containerPort: 8080
    readinessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 5
      periodSeconds: 10
    livenessProbe:
      tcpSocket:
        port: 8080
      initialDelaySeconds: 15
      periodSeconds: 20
