Kubernetes Pod因CrashLoopBackOff失败

时间：2017-06-22 14:46:00

标签： docker repository kubernetes kubectl

我关注this guide以使用minikube设置pod并从托管在以下位置的私有存储库中提取图像：hub.docker.com

当尝试设置一个pod来拉动图像时，我看到＆＃34; CrashLoopBackoff＆＃34;

pod config： 

apiVersion: v1
kind: Pod
metadata:
  name: private-reg
spec:
  containers:
    - name: private-reg-container
      image: ha/prod:latest
  imagePullSecrets:
    - name: regsecret

输出＆＃34; get pod＆＃34; 

kubectl get pod private-reg
NAME          READY     STATUS             RESTARTS   AGE
private-reg   0/1       CrashLoopBackOff   5          4m

据我所知，图像没有问题，如果我手动拉动它们并运行它们，它们就能正常工作。

（你可以看到＆＃34;成功提取图片＆＃34; ha / prod：latest＆＃34;）

如果我将通用图像推送到像centos这样的存储库并尝试使用pod来拉动并运行它，也会发生这个问题。

此外，秘密似乎工作正常，我可以看到＆＃34;拉＆＃34;计入私人存储库。

以下是命令的输出：

由于＃dock;＃34; start＆＃34;过程结束。我添加了一个永远运行的命令，它工作正常。这个问题提到了here

答案 1 :(得分：2)

由于POD初始化后出现问题，无法启动Pod。

检查并使用命令获取Pod的Docker容器

docker ps -a | grep private-reg

输出将是具有ID的docker容器的信息。

请参阅docker日志：

docker logs -f <container id>

我遇到了同样的错误。

NAME         READY   STATUS             RESTARTS   AGE
pod/webapp   0/1     CrashLoopBackOff   5          47h

我的问题是我试图使用相同的元数据名称运行两个不同的pod。

种类：豆荚 元数据：   名称：webapp   标签：...

要查找所有Pod的名称，请运行： kubectl获得豆荚

NAME         READY   STATUS    RESTARTS   AGE
webapp       1/1     Running   15         47h

然后我更改了有冲突的pod名称，一切正常。

NAME                 READY   STATUS    RESTARTS   AGE
webapp               1/1     Running   17         2d
webapp-release-0-5   1/1     Running   0          13m

当我调试获取Pod和Pod的日志时，我遇到了类似的问题“ CrashLoopBackOff”。发现我的命令参数错误

答案 4 :(得分：1)

问题在此处描述并解决 https://docs.pivotal.io/tkgi/1-10/velero-install.html。需要正确设置主机路径。

答案 5 :(得分：0)

我也有类似情况。我发现我的配置映射之一被复制了。我有两个同一个命名空间的配置映射。一个具有正确的名称空间引用，另一个则指向错误的名称空间。

我删除并使用正确的文件（或固定文件）重新创建了configmap。我只使用一个，这似乎使特定群集更快乐。

因此，我将检查文件中是否有可能引起冲突的错别字或重复项。
