Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.

   * This is usually incremented in conjunction with {@link #missCount}, though {@code missCount} is
   * also incremented when an exception is encountered during cache loading (see {@link
   * #loadExceptionCount}). Multiple concurrent misses for the same key will result in a single load
   * operation. This may be incremented not in conjunction with {@code missCount} if the load occurs

    Because the previous step copying the file could be detected by the **Docker cache**, this step will also **use the Docker cache** when available.

    Using the cache in this step will **save** you a lot of **time** when building the image again and again during development, instead of **downloading and installing** all the dependencies **every time**.

5. Copy the `./app` directory inside the `/code` directory.
