I followed the instructions and got the containers running with docker compose --profile dev up:

However, when trying to execute docker compose exec api index-cpan.sh, I got the following:
$ docker compose exec api index-cpan.sh

I am running an up-to-date Arch Linux at time of writing (2025-08-19). First, I checked that rsync is installed on my system (it was not, I installed it and rebooted). After that, I tried to execute the command with sudo, then with sudo -u myusername, but nothing doing.
Next, I wanted to check if rsync is actually installed in the api container, which appears to not be the case:
$ docker compose exec -it api bash
metacpan@080b4bb6e815:/app$ rsync --help
bash: rsync: command not found
I'll appreciate any help, hint or correction.
