For the Captive Page we can use a plain apache docker image.

Apache with a Dockerfile

FROM php:7.2-apache
COPY src/ /var/www/html/

$ docker build -t cappage .
$ docker run -d --name cappage-app cappage

 
 1718  sudo docker run -d -p 4000:80 --name cappage-app -v /home/franz/lamp/wifi-portal/public/:/var/www/html php:7.2-apache

 1744  sudo docker run -d -p 4000:80 --name cappage-app --user 33 -v /home/franz/lamp/wifi-portal/public/:/var/www/html php:7.2-apache
 1745  docker exec -it cappage-app bash
 1746  sudo docker stop cappage-app
 1747  sudo docker rm cappage-app
 1748  sudo docker run -d -p 4000:80 --name cappage-app --user 0 -v /home/franz/lamp/wifi-portal/public/:/var/www/html php:7.2-apache
 1749  docker exec -it cappage-app bash

Download Composer Latest: v2.7.2

To quickly install Composer in the current directory, run the following script in your terminal. To automate the installation, use the guide on installing Composer programmatically.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" 
php -r "if (hash_file('sha384', 'composer-setup.php') === 'dac665fdc30fdd8ec78b38b9800061b4150413ff2e3b6f88543c636f7cd84f6db9189d43a81e5503cda447da73c7e5b6') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" 
php composer-setup.php 
php -r "unlink('composer-setup.php');"

This installer script will simply check some php.ini settings, warn you if they are set incorrectly, and then download the latest composer.phar in the current directory. The 4 lines above will, in order:

• Download the installer to the current directory
• Verify the installer SHA-384, which you can also cross-check here
• Run the installer
• Remove the installer

Most likely, you want to put the composer.phar into a directory on your PATH, so you can simply call composer from any directory (Global install), using for example: sudo mv composer.phar /usr/local/bin/composer

Follow the Instructions in the README.md

# OpenWRT Coova Chilli External Captive Portal

The following actions are required to use the code given in this repo:

## Portal Setup Using Git

Suppose your domain is `hotspot.example.com`. It can be setup like this:

```
cd /var/www
git clone https://github.com/nasirhafeez/openwrt-yt-portal
mv openwrt-yt-portal hotspot.example.com
cd /var/www/hotspot.example.com
```

Copy the `.env.example` file to `.env` and set the values of the given environment variables in it:

```
cp .env.example .env
nano .env
```

Navigate to public folder:

`cd /var/www/hotspot.example.com/public`

Use [this](https://getcomposer.org/download/) link to install Composer. Then run `php composer.phar install` to install the packages given in `composer.json`.

## Apache Virtual Hosts

Apache virtual host can be setup on the portal server using the instructions given [here](https://gist.github.com/nasirhafeez/d47c9d68742227a23f1011455a190490#apache-site-setup).

The portal files are in public folder in this repository. DocumentRoot will be:

`/var/www/hotspot.example.com/public`

For the Captiva Page Database I am using phpmyadmin docker image

Example docker-compose.yml for phpmyadmin:

version: '3.1'

services:
  db:
    image: mariadb:10.6
    restart: always
    ports:
      - 4306:3306
    environment:
      MYSQL_ROOT_PASSWORD: notSecureChangeMe

  phpmyadmin:
    image: phpmyadmin
    restart: always
    ports:
      - 8080:80
    environment:
      - PMA_ARBITRARY=1

~/phpmyadmin$ sudo docker compose -f ./docker-compose.yml start

~/phpmyadmin$ sudo docker inspect phpmyadmin_default
[
    {
        "Name": "phpmyadmin_default",

                    "Subnet": "172.19.0.0/16",
                    "Gateway": "172.19.0.1"

                "Name": "phpmyadmin-phpmyadmin-1",

            },
                "Name": "phpmyadmin-db-1",

                "IPv4Address": "172.19.0.2/16",

            }
        },

]

 1767  sudo docker compose -f ./docker-compose.yml up
 1768  sudo vi docker-compose.yml 
 1769  sudo docker compose -f ./docker-compose.yml start
 1770  ls
 1771  sudo docker compose -f ./docker-compose.yml stop
 1772  sudo docker compose -f ./docker-compose.yml rm
