#+title: IpMe

* About

A self-hosted API for obtaining your public IP address.

* Live API Usage

An implementation of the API is available at [[https://ipme.fosterhangdaan.com][ipme.fosterhangdaan.com]].

| URL                                                         | Response Type | Sample Output                       |
|-------------------------------------------------------------+---------------+-------------------------------------|
| https://ipme.fosterhangdaan.com                             | text          | =98.207.254.136=                    |
| https://ipme.fosterhangdaan.com?format=json                 | json          | ={"ip":"98.207.254.136"}=           |
| https://ipme.fosterhangdaan.com?format=jsonp                | jsonp         | =callback({"ip":"98.207.254.136"})= |
| https://ipme.fosterhangdaan.com?format=jsonp&callback=getIp | jsonp         | =getIp({"ip":"98.207.254.136"})=    |

** Examples using ~curl~

To get your public IP address in plain text:

#+begin_src shell
curl --silent https://ipme.fosterhangdaan.com
#+end_src

For a response in =json= format:

#+begin_src shell
curl --silent https://ipme.fosterhangdaan.com?format=json
#+end_src

* Self-hosting

** Requirements

- [[https://podman.io/][Podman]] or [[https://www.docker.com/][Docker]] installed
- Ports 80 and 443 opened
- A domain name pointing to the server

For reliable IP address identification, the instance should be hosted on an external server outside of your home or local network.

** Compose setup

The following =compose.yaml= can be used as reference:

#+begin_src yaml
version: "3.9"

volumes:
  caddy-data:
    external: true
  caddy-config:
    external: true

networks:
  proxy-tier:
    driver: bridge

services:
  ipme:
    image: code.fosterhangdaan.com/foster/ipme:latest
    container_name: ipme
    restart: unless-stopped
    env_file: .env.ipme
    networks:
      - proxy-tier
  caddy:
    image: docker.io/library/caddy:2-alpine
    container_name: caddy
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile:ro
      - caddy-data:/data
      - caddy-config:/config
    networks:
      - proxy-tier
#+end_src

=.env.ipme=

#+begin_src env
RUN_MODE=prod
#+end_src

=Caddyfile=

#+begin_src Caddyfile
# Replace this domain with your own
https://ipme.mydomain.com {
  reverse_proxy ipme:8000
}
#+end_src

** Run the services

Run ~podman-compose up~ to start the services.

The API should be available at the domain you selected. For example: =https://ipme.mydomain.com=.
