I want to contribute to the project

[Agung Riyadi]

First contribution I want to share my docker setup for anyone who need
quick Freeradius+postgresql+backend(nodejs)+adminer in ~5 minutes.
Just run the script from terminal. :

Ready OUT-OF-THE-BOX to use packages bundle, with 4 services in
docker-compose.yml configuration:
1. freeradius server 3.2.7 as radius server.
2. postgresql 17
3. nodejs backend (akses: http://host_ip_address:5000) as basic custom UI
that can be use as basis of developing.
4. adminer (http://host_ip_address:8082) as additional general UI that can
directly access the database.

Requirement:
1. Internet connection ON the host.
2. Linux host with sudo or root access.
3. docker and docker compose must be installed. I use docker -v
Docker version 29.1.5, build 0e6fee6
and I was using this script to install docker :
curl -fsSL https://get.docker.com | sh
4. bash terminal
5. git must be installed.

JUST COPY ALL THE SCRIPT TO THE TERMINAL.
Usage :
```bash
# Must run in bash shell because of hostip.sh need it (cant use sh shell).
# Store the directory name in a variable
project_name="radiusapp"
target_dir=$project_name # you can change to any literal string as
directory name

# Check if the directory exists, and create it if it doesn't
if [ ! -d "$target_dir" ]; then
    mkdir -p "$target_dir"
    cd "$target_dir" || exit 1
    git clone https://github.com/lfsegoro/"$project_name".git .
else
    cd "$target_dir" || exit 1
    git pull # !!WARNING!! this will overwrite the directory content
fi

# to get the variable needed set
HOST_IP=$(bash ./backend/hostip.sh)
#export HOST_IP
echo "HOST_IP=$HOST_IP" > ./.env


# build process
docker compose build --no-cache
###################################################
# If you already do above you can also run below
# so you dont need to git clone and build again

# optional :
docker rm -f $(docker ps -aq -f status=exited) >/dev/null 2>&1 || true
docker network prune -f >/dev/null 2>&1 || true

docker compose up
true

```

4. Let the the script do autmatic pull and installing.
5. access from the UI.  http://host_ip_address:5000 or
http://host_ip_address:8082
6. test using Ntradping or directly from NAS like mikrotik.

You can learn the detail on the docker-compose.yml if you want to see the
password or make modification.

The database already have sample username for testing. you can check the
radcheck table.

You can test using ntradping or directly from a NAS like mikrotik.


Detailed note:
- username and password user testing, 1 entry in 'radcheck' table.
- all host/nas allowed, to see the secret: 1 entry in 'nas' table.
- adminer can have access to all table, make sure choose Postgresql, dbHost
ip ADDRESS, username/password you can see in docker-compose.yml
- the only difference with default freeradius config is modified modules
only  'sql' inside the /etc/freeradius/mods-enable
- it collude many ports udp and tcp, 1812, 1813, 3799, 5432, 5000, 8082,
8080. if you doing this kind of thing over and over you will learn a lot
backend, frontend and tcp/ip etc.
