Quickstart

Local testing

podman run -p 8080 registry.gitlab.com/jandourekjaroslav/ipinfo:latest
curl -H "X-Forwarded-For: 1.1.1.1" localhost:8080

Deployment

1. Start the service as a container To change the port from the default 8080 pass SERVICE_PORT as ENV

   podman run -d -p 8080 registry.gitlab.com/jandourekjaroslav/ipinfo:latest
   

2. Create an nginx conf file to direct traffic to it

   server {
       server_name ip.yourhostnamehere.com www.ip.yourhostnamehere.com;
   
   
   
       location / {
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_pass http://localhost:8080;
       }
   
   listen [::]:80 ;
   listen 80;
   
   }
   

3. Test your config and restart nginx

   nginx -t && systemctl restart nginx
   

4. Test it out

   curl http://ip.yourhostnamehere.com
   

   The expected output should look something like this:

   [
     {
       "ip": "1.1.1.1",
       "hostnames": ["one.one.one.one."]
     }
   ]
