Thinking about it, I really ask myself why I did not find this solution
earlier 🙈
Of course, you don't want to share the generated `buildDir`
with the host system. If you happen to share the `webapp/` folder,
simply point NuxtJS to a build directory somewhere else. Easy!
NuxtJS wants to write into .nuxt. If the docker container writes into
.nuxt it will have the file permissions of the docker container user
even on the host system. So on the host system you cannot remove the
folder .nuxt anymore. This gets in the way of running NuxtJS on the host
system.
