mutate+copy is a no-op if a field does not exist, so you can compress this down to

```
mutate {
    copy => {
        "[kubernetes][container][_module][labels]" => "[kubernetes][labels]"
        "[kubernetes][container][_module][namespace]" => "[kubernetes][namespace]"
        "[kubernetes][container][_module][node]" => "[kubernetes][node]"
        "[kubernetes][container][_module][pod]" => "[kubernetes][pod]"
        "[kubernetes][pod][_module][labels]" => "[kubernetes][labels]"
        "[kubernetes][pod][_module][namespace]" => "[kubernetes][namespace]"
        "[kubernetes][pod][_module][node]" => "[kubernetes][node]"
        "[kubernetes][node][_module][labels]" => "[kubernetes][labels]"
        "[kubernetes][volume][_module][labels]" => "[kubernetes][labels]"
        "[kubernetes][volume][_module][namespace]" => "[kubernetes][namespace]"
        "[kubernetes][volume][_module][node]" => "[kubernetes][node]"
        "[kubernetes][volume][_module][pod]" => "[kubernetes][pod]"
        "[kubernetes][system][_module][labels]" => "[kubernetes][labels]"
        "[kubernetes][system][_module][node]" => "[kubernetes][node]"
    }
 }

```

assuming that only one of the sets of node/labels/pod will be present.
