daloRADIUS docker image

A daloRADIUS docker image configurable via environment variables.

Building

This container must be built from a clone of this repository (or any valid fork), as git is used in the container to perform patches that allow it to be configured using environment variables. The --recursive flag must be used when cloning, as the daloradius submodule contains the necessary files to install daloRADIUS on the container. If that is checked, the usual docker build -t "daloradius" . should do it.

For example

IMAGE_NAME="daloradius"
# Cloning from a local git repo
REPO_ORIGIN="./docker-daloradius.git"
git clone --recursive "$REPO_ORIGIN" ./daloradius-docker
cd ./daloradius-docker
docker build -t "$IMAGE_NAME" .

Running

Environment configuration

Variable name	Description	Default value
RADIUS_DB_HOST	Hostname or address for the MySQL server	error
RADIUS_DB_PORT	Port of the MySQL server	3306
RADIUS_DB_NAME	Name of the radius database	error
RADIUS_DB_USER	Username for a user with access to the radius database	error
RADIUS_DB_PASS	Password for that user	error

Ports 80 and 443 are exposed, you need to publish the ones you need. The variables that error by default must be provided to the container on initialization.

For example

IMAGE_NAME="daloradius"
docker run  -itd \
    --name daloradius \
    -e RADIUS_DB_HOST=myslq \
    -e RADIUS_DB_USER=freeradius \
    -e RADIUS_DB_PASS=radpass \
    -e RADIUS_DB_NAME=freeradius \
    -p 8080:80 \
    "$IMAGE_NAME"

This will create a container running detached with TTY, named daloradius from the image $IMAGE_NAME that accesses a MySQL server with hostname myslq (at the default port), as user freeradius with password radius to the database named freeradius, that then publishes the internal port 80 to the port 8080.

Database initialization

Scripts for initializing the MySQL database can be found on the contrib/db/ directory of the daloRADIUS project, or in the /var/www/html/contrib/db/ directory of this image.

For example

Say you have a mysql container that servers as a datastore for a freeRADIUS installation, in that case you can initialize the database with these commands.

# Usually the default script is want you want
DB_SCRIPT="mysql-daloradius.sql"
DR_CONTAINER_NAME="daloradius"
MYSQL_CONTAINER_NAME="mysql"
DB_USER="freeradius"
DB_PASS="radpass"
DB_NAME="freeradius"

docker exec "$DR_CONTAINER_NAME" \
    cat "/var/www/html/contrib/db/$DB_SCRIPT" |
docker exec "$MYSQL_CONTAINER_NAME" \
    mysql \
        "-u${DB_USER}" \
        "-p${DB_PASS}" \
        "$DB_NAME"
