Web shutdown

This small utility helps to shutdown your host via web UI interface.

It is only tested in Ubuntu, other platforms might need to tweak a little bit, but it should be quite easy.

1. Clone to your host

   git clone https://github.com/JerryBian/web-shutdown.git /tmp/web-shutdown
   

2. Install modules

   cd /tmp/web-shutdown
   pip3 install -r requirements.txt
   

3. Create Systemd unit file

   python3_bin=$(which python3)
   
   echo "
   [Unit]
   Description=shutdown via web
   After=network.target
   
   [Service]
   User=root
   WorkingDirectory=/tmp/web-shutdown
   Restart=on-failure
   RestartSec=5s
   ExecStart=$python3_bin app.py
   
   [Install]
   WantedBy=multi-user.target
    " > /etc/systemd/system/web-shutdown.service
   
   systemctl enable web-shutdown
   systemctl start web-shutdown
   

In order to send notifications during startup/shutdown, you have to setup 2 variables:

• ENV_SENDGRID_API_KEY: you could create free account to get the api key of SendGrid
• ENV_MAIL_TO_ADDR: the email address send to

Optionally, you can specify more detailed configurations:

• ENV_MAIL_TO_NAME: the name send to
• ENV_MAIL_FROM_ADDR: the email address send from
• ENV_MAIL_FROM_TO: the name send from

• ENV_SECRET_KEY: secret key for authentication
• ENV_USER_NAME: user name. Default: admin
• ENV_PASSWORD: user password. Default: adminadmin
• ENV_HOST: the hostname to listen on. Default: 127.0.0.1
• ENV_PORT: the port to listen on. Default: 5000
