Docker build? about pdf-bot HOT 1 OPEN

I am not an expert in Docker containers but I was able to create a working version based on Ubuntu with a cronjob that runs every minute. You will need 3 files:

pdf-bot.config_docker.js
module.exports = {
"api": {
"token": "my-test-token"
},
"storagePath": "/app/pdf-storage",
generator: {
port : 9222
}
}

cronjob_shiftall
* * * * * node $(npm bin -g)/pdf-bot -c ../app/pdf-bot.config_docker.js shift:all >> /var/log/pdfbot.log 2>&1

Dockerfile
