Building in Docker

Prerequisities

only Docker

No need to install ESP-IDF or anything else. All commands should be run in a project root.

menuconfig

docker run --rm -it -v .:/project -w /project espressif/idf:v4.3.1 idf.py menuconfig

Build

docker run --rm -it -v .:/project -w /project espressif/idf:v4.3.1 idf.py build

Flash

Mapping of serial port to container is not simple in windows but you can merge all generated bin files into single firmware and flash the firmware manually using some windows tool.

Merge bins into single firmware bin file

docker run --rm -it -v .:/project -w /project/build espressif/idf:v4.3.1    //runs terminal in idf container

esptool.py --chip esp32 merge_bin --output firmware.bin @flash_args         // merges all bin files into firmware.bin

Write build/firmware.bin to ESP32 at address 0x0000

docker run
    --rm                            // Removes container after exit
    -it                             // runs interactive terminal
    -v .:/project                   // maps current directory to /project in container
    -w /project                     // sets working directory inside a container to /project
    espressif/idf:v4.3.5            // image name + version
    idf.py menuconfig               // run menuconfig
