I saw this after modifying the php-startup-7.3 folder for running apt update:

The same happens if I add a line to that file, say, apt install php-mailparse
I don’t think adding another extension to the php-fpm container is necessary for this to work; the whole idea of a php-startup folder and its related files is to do custom setups without changing the image itself. Has anyone come across this?
The only thing I can think of is that to make DNS work for Devilbox I had to add the localhost DNS to the vEthernet (WSL) adapter running my wsl2 instance. Without that change, automatic DNS fails in Docker for Windows using WSL2.
I also tried running apt update from within the php-fpm container and the result is the same, no resolution.
Update:
I removed the localhost entry in the WSL network adapter to see if it’s the culprit, but no, the behavior is the same. I’m starting to think this should be a bug instead of posting here…
