My money is on the additional `git pull` is _unnecessary_, because of the code here:

> <https://github.com/discourse/discourse_docker/blob/8e2ccee0f2989885632c27c7f33a87719d3838ec/launcher#L744>

which seems to check the local version, updates and restarts the launcher if out of date (and a bunch of other things).

Therefore only this should be necessary on subsequent rebuilds:

```plaintext
cd /var/discourse
./launcher rebuild app

```

_without_ the redundant git pull.

(NB: always good to dive into the source code so you can be more sure).  
(NB#2: have deleted my post above which just added to the confusion).
