You don’t need to rebuild the data container unless there is an upgrade to postgres (as just happened) or redis (which happened in the last 6 months or so).

Mostly you just replace web\_only for app in the instructions you see. I have notes at [Managing a Two-Container Installation - Documentation - Literate Computing Support](https://support.literatecomputing.com/t/managing-a-two-container-installation/310)
