Hello Tuleap Team,

Firstly, I would like to congratulate you for the great work! ;)

Recently, I have worked with the setup environment with Docker Compose, and I noticed that the variable REALTIME_KEY was not defined:

...
311     @echo "LDAP_MANAGER_PASSWORD=`env LC_CTYPE=C tr -dc 'a-zA-Z0-9' < /dev/urandom | head -c 32`" >> .env
312     @echo VIRTUAL_HOST=tuleap-web.tuleap-aio-dev.docker >> .env
313     @echo "REALTIME_KEY=$(head -c 64 /dev/urandom | base64 --wrap=88)" >> .env
314
...

The shell function is missing into the variable, but for consistency, the backquotes are most appropriate in my opinion:

...
311     @echo "LDAP_MANAGER_PASSWORD=`env LC_CTYPE=C tr -dc 'a-zA-Z0-9' < /dev/urandom | head -c 32`" >> .env
312     @echo VIRTUAL_HOST=tuleap-web.tuleap-aio-dev.docker >> .env
313     @echo "REALTIME_KEY=`head -c 64 /dev/urandom | base64 --wrap=88`" >> .env
314
...

Thank you,
