Question

我原本试图运行一个似乎陷入CrashBackoffLoop的Job。这是服务文件：

apiVersion: batch/v1
kind: Job
metadata:
  name: es-setup-indexes
  namespace: elk-test
spec:
  template:
    metadata:
      name: es-setup-indexes
    spec:
      containers:
      - name: es-setup-indexes
        image: appropriate/curl
        command: ['curl -H  "Content-Type: application/json" -XPUT http://elasticsearch.elk-test.svc.cluster.local:9200/_template/filebeat -d@/etc/filebeat/filebeat.template.json']
        volumeMounts:
        - name: configmap-volume
          mountPath: /etc/filebeat/filebeat.template.json
          subPath: filebeat.template.json
      restartPolicy: Never

      volumes:
        - name: configmap-volume
          configMap:
            name: elasticsearch-configmap-indexes

我尝试删除该作业，但只有在运行以下命令时才会起作用：

kubectl delete job es-setup-indexes --cascade=false

之后我发现跑步时注意到了：

kubectl get pods -w

我会得到一个处于错误状态的TON的pod，我认为没办法清理它们。以下是运行get pods时输出的一小部分示例：

但是，如果我看看这些工作，我就不会再与此相关了：

$ kubectl get jobs --all-namespaces                                                                              
NAMESPACE     NAME               DESIRED   SUCCESSFUL   AGE
kube-system   configure-calico   1         1            46d

我也注意到kubectl的反应似乎很慢。我不知道pod是不是一直在尝试重新启动或处于某种破坏状态，但如果有人能让我知道如何排除故障会很好，因为我没有在kubernetes中遇到过这样的问题。

Kube信息：

$ kubectl version

Answer 1

在这里，您可以快速解决问题：）

kubectl get pods -a | grep Error | cut -d' ' -f 1 | xargs kubectl delete pod

Answer 2

Vector3 stairSize; float stepWidthFactor=1f; Vector3 stairsStartPosition; private IEnumerator BuildStairs() { for (int i = 0; i <= stairsNumber ; i++) { stairsPosition = new Vector3( stairsStartPosition.x, stairsStartPosition.y + stairsHeight, stairsStartPosition.z + stairsHeight*stepWidthFactor); GameObject stairs = Instantiate( stairsPrefab, stairsPosition, Quaternion.identity); stairsHeight += stairsSize.y; stairs.transform.localScale = stairSize; yield return new WaitForSeconds(delay); } }

...清理您的命名空间中所有失败的Pod。

Answer 3

我通常会使用此命令删除所有Error窗格。 kubectl delete pod `kubectl get pods --namespace <yournamespace> | awk '$3 == "Error" {print $1}'` --namespace <yournamespace>

Answer 4

解决方案是评论中提到的@ johnharris85。我不得不手动删除所有的pod。为此，我运行了以下内容：

kubectl get pods -w | tee all-pods.txt

抛弃我的所有吊舱，然后过滤和删除我想要的东西。

kubectl delete pod $(more all-pods.txt | grep es-setup-index | awk '{print $1}')

注意： 我有大约9292个播客，大约需要1-2个小时来删除它们。

Kubernetes有大量处于错误状态的pod似乎无法清除
