How does one change the default port?

[Boffice]

Shell i change all port manually in dockerfile and other places ?
is there any parameter or ENV to change it everywhere ?

8000 is busy port for me (Bind for 0.0.0.0:8000 failed: port is already allocated)

Hello @Boffice there is a .env file in the root folder where you can change the ports
