Try to host a general-purpose express app

If this works (needs testing on a Pi) we can add more utilities, like a commandline prompt, maybe, a file uploader, a bulk image downloader, or maybe most importantly, a way to change the WiFi settings:

• the network name and password Ability to insert random number or string into config files like WiFi #23
• connect the Pi to another network Ability to switch WiFi network off and connect to another WiFi network #64

This basic test addresses #66, read access to filesystem.

Thanks for opening a pull request! In this repository, opening a PR will initiate the generation of a new Raspberry Pi image, and create an image file you can download and use in your Raspberry Pi.

The changes you add to the pull request, such as adding software to install, will be run on the generated image.

For an example, see the software installed and configured in this pull request: https://github.com/publiclab/image-builder-rpi/pull/15/files

Download instructions

Generating the image will take a few minutes. Once the image is prepared, and if it succeeded, you'll see a green checkmark at the bottom of the pull request. To download the image:

1. click the green checkmark; you'll go to a page at a URL like https://gitlab.com/publiclab/image-builder-rpi/pipelines/########/builds
2. On this page, click the Jobs tab, next to Pipeline
3. Click the green Passed button
4. Click Download in the right-hand sidebar
5. Unzip the artifacts.zip file, and also the hypriotos-rpi-camera_web.img.zip within it
6. Use a program like https://etcher.io/ to flash it to an SD card

You'll also be able to read the output of the image generation in this window.

We hope to create a bot to report back the completed image URL in each pull request. If you can help create such a bot, please contact us at:
