A simple country lookup for IP addresses using CSV files such as the MaxMind free database.
curl http://data-services.c8online.com:3000/api/addresses -X POST -d '{"ip_address": "195.171.93.18"}' -H 'Content-Type: application/json'The app is very simply installed onto data-services.c8online.com and listens on port 3000 (so ufw and the Brightbox firewall both have that port opened).
The files are in /home/app/gio and the docker-compose.yml is used to build a docker image. The database is in /home/app/gio/data.
Then a systemd service has been configured to ensure the app stays running. This is in /etc/systemd/system/gio.service and looks like this:
[Unit]
Description=Gio
Requires=docker.service
After=docker.service
[Service]
WorkingDirectory=/home/app/gio
Restart=always
ExecStart=/usr/bin/docker-compose up
ExecStop=/usr/bin/docker-compose down
[Install]
WantedBy=multi-user.target
Use sudo systemctl daemon-reload to ensure systemd knows about the service, then sudo service gio start to start the service.
There is a deploy script in the bin folder that simply copies the current code to the server, stops the service, uses docker-compose to rebuild the image and run migrations, then restarts the service.
Nothing fancy but it does the job.
Ideally we'd stick HTTPS over the front-end but there's nothing secure going on here.
