Docker PlatformIO Core

This is a Dockerfile packaging PlatformIO Core. The image contains the PlatformIO Command Line Interface for developing software for embedded devices and IoT projects. To speedup development, this image has the platform espressif8266 already installed.

Continuous Integration

Github Actions

It is very easy to have CI features for your project using GitHub Actions and this Docker image. To set this up, create a file called build.yml in the folder .github/workflows and add the following content:

name: Build

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: docker://sglahn/platformio-core:latest
        with:
          args: run

This will trigger a build with platformio-core on every push in every branch.

Jenkins Pipeline

Here is a very simple Jenkins pipeline example:

pipeline {
    agent any
    triggers { cron('H 4/* 0 0 1-5') }

    stages {
        stage('Build') {
            steps {
                git 'https://github.com/platformio/platformio-examples.git'

                sh 'docker run --rm \
                    --mount type=bind,source="$(pwd)/wiring-blink",target=/workspace \
                    -u `id -u $USER`:`id -g $USER` \
                    sglahn/platformio-core:latest \
                    run'
            }
        }
    }
}

Jenkins will periodically poll the SCM repository for changes and trigger a build with platformio-core.

Manual Usage

Add the script platformio.sh to your path and run platformio < options >.

Uploading

For convenience, the script checks if the host device /dev/ttyUSB0 is available and adds this device to the Docker container. You can override this device by setting the environment variable UPLOAD_PORT.

Step By Step

Pull the image

docker pull sglahn/platformio-core:latest

Run a Docker container

docker run --rm \
    --mount type=bind,source="$(pwd)",target=/workspace \
    -u `id -u $USER`:`id -g $USER` \
    --device=/dev/ttyUSB0 \
    sglahn/platformio-core:latest \

With <PROJECT_DIR> as the directory containing your work, e.g. ~/Workspace/myproject/.

Examples

With this Docker image you can for example, create a new project:

docker run --rm \
    --mount type=bind,source="$(pwd)",target=/workspace \
    -u `id -u $USER`:`id -g $USER` \
    sglahn/platformio-core:latest \
    init --board uno

Compile a project:

docker run --rm \
    --mount type=bind,source="$(pwd)",target=/workspace \
    -u `id -u $USER`:`id -g $USER` \
    --device=/dev/ttyUSB0 \
    sglahn/platformio-core:latest \
    run

Or upload your project to a board connected to the PC:

docker run --rm \
    --mount type=bind,source="$(pwd)",target=/workspace \
    -u `id -u $USER`:`id -g $USER` \
    --device=/dev/ttyUSB0 \
    sglahn/platformio-core:latest \
    run -t upload

Keep Configuration

If you want to keep the downloaded packages, etc. you can save the PlatformIO configuration outside of the container. You can do this by adding the following line to the docker run call:

-v `$HOME/.platformio`:/.platformio \

Alternatively you could use a data volume container to save the PlatformIO configuration. First create the data volume container

docker run --name vc_platformio sglahn/vc_platformio:latest

Then add the following line to the docker run call:

--volumes-from=vc_platformio \
