Compiling with docker for ESP32 with espressif/idf:release-v5.2 image

[DavideRossi]

I found a few suggestions online on how to build with docker, but things broke with the 5.2 idf image.

If you ever need it, that's what worked for me:

USRHOME=$(mktemp -d -p /tmp); docker run -ti --rm --user $(id -u):$(id -g) -v $USRHOME:/usrhome -v $(pwd):/micropython -w /micropython espressif/idf:release-v5.2 bash -c "export HOME=/usrhome && git config --global --add safe.directory '*' && make -C mpy-cross && cd ports/esp32 && make submodules -j4 && make -j4"; rm -rf $USRHOME

Of course you might need BOARD=... after make.
