<p>I'm testing kubernetes behavior when pod getting error.</p>
<p>I now have a pod in CrashLoopBackOff status caused by liveness probe failed, from what I can see in kubernetes events, pod turns into CrashLoopBackOff after 3 times try and begin to back off restarting, but the related Liveness probe failed events won't update?</p>

</code></pre>
<p>BackOff event updated 118s ago, but Unhealthy event updated 16m ago?</p>
<p>and why I'm getting only 15 times Restart Count while BackOff events with 134 times?</p>
<p>I'm using minikube and my deployment is like this:</p>
<pre><code>apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx-liveness-err
spec:
  selector:
    matchLabels:
      run: my-nginx-liveness-err
  replicas: 1
  template:
    metadata:
      labels:
        run: my-nginx-liveness-err
    spec:
      containers:
      - name: my-nginx-liveness-err
        image: nginx
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80
        livenessProbe:
          httpGet:
            path: /
            port: 8080
</code></pre>

<p>I think you might be confusing Status Conditions and Events. Events don't &quot;update&quot;, they just exist. It's a stream of event data from the controllers for debugging or alerting on. The <code>Age</code> column is the relative timestamp to the most recent instance of that event type and you can see if does some basic de-duplication. Events also age out after a few hours to keep the database from exploding.</p>
<p>So your issue has nothing to do with the liveness probe, your container is crashing on startup.</p>
