Question

我正在尝试在kubernetes集群中运行一个简单的ubuntu容器。它继续以CrashLoopBackOff状态失败。我什至看不到任何日志来查找原因。

我的Yaml文件如下所示：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ubuntu
  labels:
     app: jubuntu
spec:
    selector:
      matchLabels:
        app: jubuntu
    template:
      metadata:
         labels:
            app: jubuntu
      spec:
         containers:
            - name: ubuntu
              image: ubuntu

那是因为您使用的<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/foundation/6.4.3/js/foundation.min.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/foundation/6.4.3/css/foundation.min.css" rel="stylesheet"/>  <div class="main"> <div class="row"> <div class="columns"> <h2>Accordion</h2> <p>Accordions lets you organize and navigate multiple documents in a single container. Highly useful for switching between items in the container specially when you have a large amount of content.</p> </div> </div> <div class="row"> <div class="columns"> <ul class="accordion" data-accordion data-allow-all-closed="true"> <li class="accordion-item with-button" data-accordion-item> <a href="#" class="accordion-title my-brother-is-a-button">Accordion 1</a> <a href="https://google.com" class="tiny button within-title">button that should lead to a target link</a> <div class="accordion-content" data-tab-content > <p>Panel 1.

另请参阅this troubleshooting guide。

为方便起见，如果不想通过编辑YAML清单来执行此操作，也可以使用以下命令：

command:
- sh
- '-c'
- "while true; do echo working ; sleep 5; done;"

如果您非常好奇并想检查是否相同，则可以将以下内容附加到运行命令：$ kubectl run --image=ubuntu -- sh while true; do echo working ; sleep 5; done;（在--dry-run --output=yaml之后，在--image之前）

容器不以状态CrashLoopBackOff开头
