PlatformIO Docker Build
IoT application developers
They just need a ready-made firmware.
Occasional firmware hackers
They don't need full control over the complete tool chain and don't want to setup a Linux VM with the build environment.
This image has been created for purposes of the THiNX IoT management platform.
Follow the instructions at https://docs.docker.com/get-started/.
Run this image with Docker
Start terminal and change to the your PlatformIO project directory. Then run:
docker run --rm -ti -v `pwd`:/opt/workspace suculent/platformio-docker-build
Depending on the performance of your system it takes 1-3min until the compilation finishes. The first time you run this it takes longer because Docker needs to download the image and create a container.
docker pull suculent/platformio-docker-build
Note for Windows users
(Docker on) Windows handles paths slightly differently. The command thus becomes (
c equals C drive i.e.
docker run --rm -it -v //c/Users/<user>/<workspace>:/opt/platformio-builder suculent/platformio-docker-build
If the Windows path contains spaces it would have to be wrapped in quotes as usual on Windows.
`docker run --rm -it -v "//c/Users/monster tune/"/opt/workspace suculent/platformio-docker-build``
The firmware file is created in the
bin sub folder of your root directory. You will also find a mapfile in the
bin folder with the same name as the firmware file but with a
You can pass the following optional parameters to the Docker build like so
docker run -e "<parameter>=value" -e ....
WORKDIRJust an parametrization example, will deprecate or be used for additional libraries.
Flashing the built binary
esptool.py --port <USB-port-with-ESP8266> write_flash 0x00000 <workspace>/bin/firmware.bin
You may edit Dockerfile in order to pre-build image with your preferred platform. Initially, this image is configured to kick-start builds for ESP8266 and ESP32.
Don't leave comments on Docker Hub that are intended to be support requests. First, Docker Hub doesn't notify me when you write them, second I can't properly reply and third even if I could often it doesn't make much sense to keep them around forever and a day. Instead ask a question on StackOverflow and assign the
