Before pressing the “END EXAM” button, please ensure that the server is up and running.

And you should also familiarize yourself with how to debug crashed API server. If you leave any cluster broken, then marking scripts cannot connect and all questions using the broken cluster will score zero.

# How to Diagnose a Crashed API Server

The API server pod won't come back up - HELP :scream: :scream: :scream:

Perhaps you've made a manifest edit, or perhaps some question has put you into a context where the API server is already broken. You're using `docker ps` or `crictl ps` and see the API server flash up briefly then go away. The container doesn't last long enough for you to grab an ID to pull logs from. Or maybe it never appears in the `ps` output.

Note that these techniques can be used for the other static pods like `etcd` by looking for `etcd` instead of `apiserver` in the commands below.

Steps to take

1.  Restart `kubelet` so you don't have to wait too long in the following steps</br></br>
    ```
    systemctl restart kubelet
    ```

1.  Determine if the kubelet can even start the API server</br></br>
    If there is a syntax error in the YAML manifest, then kubelet will not be able to parse it and will eventually complain. Do the following and watch the output for up to 60 seconds. Note that if you have errors in your pod manifest, kubelet will report them exactly the same way using the [same kind of error messages](./yaml-faq.md#dealing-with-errors) that kubectl does!

    ```
    journalctl -fu kubelet | grep apiserver
