title: Is it possible to install curl into busybox in kubernetes pod
body: <p>I am using busybox to detect my network problem in kubernetes v1.18 pods. I created the busybox like this:</p>
  <pre><code>apiVersion: v1
  kind: Pod
  metadata:
      name: busybox
      namespace: default
  spec:
      containers:
      - name: busybox
      image: busybox:1.28
      command:
          - sleep
          - &quot;3600&quot;
      imagePullPolicy: IfNotPresent
      restartPolicy: Always
  </code></pre>
  <p>and login to find the kubernetes clusters  network situation:</p>
  <pre><code> kubectl exec -it busybox /bin/bash
  </code></pre>
  <p>What surprises me is that the busybox does not contain curl. Why does the busybox package not include the curl command? I am searching the internet and find the docs do not talk about how to add curl into busybox. I tried to install curl, but found no way to do this. Is there anyway to add curl package into busybox?</p>
