Docker Platformio Core

Abstract

1. Introduction

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.

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

2. Objective

PlatformIO Command Line Interface in a Docker Container. Tags:

This project demonstrates how Dockerfile, Docker, Arduino can be applied to a real-world Internet of Things (IoT) problem.
