title: kubectl exec works on single commands, but I cannot enter a bash shell
body: <p>I'm on <strong>macOS Catalina 10.15.4</strong>, and I'm using <strong>minikube v1.11.0</strong> and <strong>kubernetes v1.18.3</strong>, both installed from brew. Minikube is initialized with the docker engine.</p>
  <p>The initialization command is set up like so:</p>
  <pre><code>      containers:
          - name: database
            image: &quot;mysql:5.6&quot;
            imagePullPolicy: IfNotPresent
            env:
              - name: MYSQL_ROOT_PASSWORD
                value: 12345
              - name: MYSQL_USER
                value: user
              - name: MYSQL_PASSWORD
                value: password
              - name: MYSQL_DATABASE
                value: db
  </code></pre>
  <p><strong>I'm trying to get a bash script open for one of my running kubectl containers.</strong> From research online, it appears that this should be the command that will open a bash window in my terminal:</p>
  <p><code>minikube kubectl exec -it --namespace=tools test-pod -- bash</code></p>
  <p><strong>However, when I run it, I get the following traceback:</strong></p>
  <p><code>Error: unknown shorthand flag: 'i' in -it See 'minikube kubectl --help' for usage.</code></p>
  <p><strong>It doesn't seem to want me using any arguments in my command.</strong> Is there something I'm missing, or am I attempting to use a command that is deprecated?</p>
  <p><strong>Note: I am able to run</strong> <code>exec</code>, but not for opening a bash script. For example, I am able to run the following command:</p>
  <p><code>minikube kubectl exec test-pod -- ls /</code></p>
  <p>And it outputs this following:</p>
  <pre><code>kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl kubectl exec [POD] -- [COMMAND] instead.
  bin
  boot
  dev
  docker-entrypoint-initdb.d
  entrypoint.sh
  etc
  home
  lib
  lib64
  media
  mnt
  opt
  proc
  root
  run
  sbin
  srv
  sys
  tmp
  usr
  var
  </code></pre>
  <p><strong>Edit:</strong> I have attempted the following command:</p>
  <pre><code>minikube kubectl exec --stdin --tty --namespace=tools test-pod -- sh
  </code></pre>
  <p>And I got the following traceback:</p>
  <pre><code>Error: unknown flag: --stdin
  See 'minikube kubectl --help' for usage.
  </code></pre>
  <p>It seems like any flags at all, short or long, are failing, and I cannot figure out why they wouldn't be.</p>
