A Work Instructions Flask App
This app is intended to display work instructions for an operator working through a process. The page shows the user an image and written instructions, as well as inputs to record data. This data can be downloaded lata as a csv file.
The work instructions can be set through the app, with different instructions and data for different parts.
Create config.py in the root folder from example-confs/config-example.py and edit config options. Modify the secret key to a random string
Run npm install in the /app/static directory to download js dependencies.
Run npm run build to build the bootstrap styles.
Run pip install -r requirements.txt in a virtual environment if necessary.
Gunicorn is recommended, install with pip install gunicorn
To run at startup, an example config for systemd is provided in the example-confs folder. Copy to /etc/systemd/system and run sudo systemctl daemon-reload then sudo systemctl enable work_instructions. Make sure to edit the paths in the service config files.
For security, the app should be run by a different user. For example, create a user called flask useradd flask and give them ownership of the app chown -R flask /home/user/work_instructions_webapp. Ensure the app is started by the same user in your systemd service files.
The software ideally uses nginx as a reverse proxy. This can be installed with sudo apt install nginx. An example config is included in this repo. In order for the android app to work correctly, the proxy server must pass on the IP address of the android client.
