    the certificate that follows and the last certificate is signed by a trusted root.

 *  Fix: Don't lose HTTP/2 flow control bytes when incoming data races with a stream close. If this
    happened enough then eventually the connection would stall.

Dann, gegen Ende des `Dockerfile`s, kopieren wir den gesamten Code. Da sich der **am häufigsten ändert**, platzieren wir das am Ende, da fast immer alles nach diesem Schritt nicht mehr in der Lage sein wird, den Cache zu verwenden.

```Dockerfile
COPY ./app /code/app
