Docker image rebuilds all every time, doesn't do incremental build (IDFGH-2720)

[ftab]

Environment

• Development Kit: ESP32-LyraT
• Module or chip used: ESP32-WROVER
• IDF version (run git describe --tags to find it): v3.3.1 docker image - espressif/idf:v3.3.1
• Build System: Make
• Compiler version (run xtensa-esp32-elf-gcc --version to find it): 1.22.0-80-g6c4433a
• Operating System: Linux
• Using an IDE?: No
• Power Supply: USB
• Docker version: 18.09.9

Problem Description

When building an application (e.g. hello world example) it does not do an incremental build on future runs.

Expected Behavior

Incremental build, future runs should not have to rebuild if the source did not change

Actual Behavior

Full project is built every time.

Steps to reproduce

1. Plug ESP32 board into /dev/ttyUSB0
2. Install docker-ce (18.09.9 in my case)
3. Check out esp-idf at v3.3.1
4. cd to examples/getting-started/hello_world or cp -a examples/getting-started/hello_world elsewhere and then cd to there
5. Set up default config: docker run -it -v $PWD:/project -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1 make defconfig
6. Build, flash, monitor: docker run -it -v $PWD:/project -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1 make -j flash monitor
   Make sure to do the boot button dance if you do not have the jumpers set for automatic boot/flashing
7. Ctrl+] to exit after satisfied it is running
8. Run docker run -it -v $PWD:/project -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1 make monitor

It tries to rebuild the whole project (all components) again.

Code to reproduce this issue

https://github.com/espressif/esp-idf/tree/v3.3.1/examples/get-started/hello_world

Debug Logs

The code runs fine, it is the build process that does not reuse the existing objects. A full rebuild is done every time, and that takes quite some time on some computers.

$ docker run -it -v $PWD:/project -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1 make -j flash monitor
Adding ESP-IDF tools to PATH...
Checking if Python packages are up to date...
Python requirements from /opt/esp/idf/requirements.txt are satisfied.
Added the following directories to PATH:
  /opt/esp/idf/components/esptool_py/esptool
  /opt/esp/idf/components/espcoredump
  /opt/esp/idf/components/partition_table/
  /opt/esp/tools/xtensa-esp32-elf/1.22.0-80-g6c4433a-5.2.0/xtensa-esp32-elf/bin
  /opt/esp/tools/esp32ulp-elf/2.28.51.20170517/esp32ulp-elf-binutils/bin
  /opt/esp/tools/openocd-esp32/v0.10.0-esp32-20190313/openocd-esp32/bin
  /opt/esp/python_env/idf3.3_py3.6_env/bin
  /opt/esp/idf/tools
Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build

Unfortunately this is related to the fact that in Make build system, Kconfig tools are built in the ESP-IDF directory, not in the project build directory. Therefore the conf binary gets rebuilt every time you start the build in a container. Since sdkconfig and sdkconfig.h are its dependencies, they get rebuilt as well, and because of them, all the project sources get rebuilt.

This problem (kconfig tools built in IDF directory) is solved in the CMake build system. If you are starting a new project, I would recommend starting with CMake.

If that is not an option, you can start a named container (and without the --rm flag), and then execute the build in the running container using docker exec.

[ftab]

@igrr Thanks so much for the quick response!

I'd love to use CMake instead, but it looks like ESP-ADF hasn't been updated for it (or at least some examples aren't).

I have esp-idf and esp-adf natively on my main machine so I've tried that before messing with the Docker image further, but I get errors trying to do idf.py build on esp-adf/examples/get-started/pipeline_a2dp_sink_and_hfp with either esp-adf master or v2.0-beta2

This is the one my current project is most like.

Running the named container, how would that look? I tried this but didn't get very far

docker run --name idf -it -v $PWD:/project -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1

I get to a bash terminal and can build and flash it once through make -j flash monitor, but I've got to stay in the container. It stops the container when I exit. If I try docker start idf I can't exec in after the fact.

build@build:~/esp/hello_world$ docker start idf
idf
build@build:~/esp/hello_world$ docker exec -it idf make -j flash monitor
make: xtensa-esp32-elf-gcc: Command not found

Similar path-style issues with idf.py

build@build:~/esp/hello_world$ docker start idf
idf
build@build:~/esp/hello_world$ docker exec -it idf idf.py build flash monitor
OCI runtime exec failed: exec failed: container_linux.go:346: starting container process caused "exec: \"idf.py\": executable file not found in $PATH": unknown

Did I do that wrong?

Ah, I see, the entry point script doesn't get executed when doing docker exec... Okay, as another option, you may try to mount a named volume into the /opt/esp/idf/tools/kconfig of the container. The first time the empty volume is mounted, it will be initialized with the data from the container. To do this, add another -v argument -v kconfig:/opt/esp/idf/tools/kconfig to your original docker run command.

I've tested the following and it seems to work:

docker run --rm -it -v $PWD:/project -v kconfig:/opt/esp/idf/tools/kconfig -w /project espressif/idf make

Will add this recipe to the documentation.

Yep, that seems to do the trick!

With /dev/ttyUSB0 hooked up:

docker run --rm -it -v $PWD:/project -v kconfig:/opt/esp/idf/tools/kconfig -w /project --device=/dev/ttyUSB0 espressif/idf:v3.3.1 make -j flash monitor

Subsequent runs just flash and monitor.

I've also tested this with my custom combined IDF/ADF image and verified it works with make -j flash monitor and make monitor

I will try to update my project with cmake so I can just use idf.py build flash monitor

Thanks!
