radiobrowser-api-rust

What is radiobrowser-api-rust?

In short it is an API for an index of web streams (audio and video). Streams can be added and searched by any user of the API.

There is an official deployment of this software that is also freely usable at https://api.radio-browser.info

Features

  • Open source
  • Freely licensed
  • Well documented API
  • Automatic regular online checking of streams
  • Highliy configurable
  • Easy setup for multiple configurations (native, deb-packages, docker, ansible)
  • Implemented in Rust-lang
  • Multiple request types: query, json, x-www-form-urlencoded, form-data
  • Multiple output types: xml, json, m3u, pls, xspf, ttl, csv
  • Optional: multi-server setup with automatic mirroring
  • Optional: response caching in internal or external cache (redis, memcached)

Setup

You can do a native setup or a docker setup

easy all-in-one docker setup with automatic TLS from Let's Encrypt

install

  • This has been tested on Ubuntu 20.04 LTS
  • Automatic redirect from HTTP to HTTPS
  • Automatic generation and update of Let's Encrypt certificates
  • Automatic start on reboot
  • Automatic fetch of station changes and check information from main server
  • A+ rating on https://www.ssllabs.com/ssltest/
# create radiobrowser directory

# set email and domain, they are needed for automatic certificate generation and for the reverse proxy that is included in the package
export SOURCE="my.domain.org"

# OPTIONAL: enable checking of stations, this does check all stations once every 24 hours
export ENABLE_CHECK="true"
# deploy app stack

Requirements:

# install packages (ubuntu 18.04)
curl https://sh.rustup.rs -sSf | sh
sudo apt install libssl-dev pkg-config gcc
sudo apt install default-mysql-server
# clone repository
git clone https://github.com/segler-alex/radiobrowser-api-rust ~/radio

docker setup

# start db and api server
docker-compose up --abort-on-container-exit

docker from registry

The repository is at https://hub.docker.com/repository/docker/segleralex/radiobrowser-api-rust

# !!! DO NOT USE THE FOLLOWING FOR PRODUCTION !!!
# It is just for a quickstart and is a minimal setup.

# create virtual network for communication between database and backend
docker network create rbnet
# start database container
docker run \
    --name dbserver \
    --detach \
    --network rbnet \
    --rm \
    -e MYSQL_DATABASE=radio \

# show logs

# access api with the following link
# http://localhost:8080
# stop radiobrowser container
docker rm -f radiobrowserapi
# stop database container
docker rm -f dbserver
# remove the virtual network
docker network rm rbnet

SSL

Radiobrowser does not yet support connecting with https to it directly. You have to add a reverse proxy like Apache or Nginx.

Apache config

# install packages (ubuntu 18.04)
sudo apt install apache2

# enable apache modules
sudo a2enmod proxy_http
sudo systemctl restart apache2
sudo mkdir -p  /var/www/radio

Apache config file example

<VirtualHost *:80>
    ServerName my.servername.com

    ServerAdmin webmaster@programmierecke.net
    DocumentRoot /var/www/radio

    ErrorLog ${APACHE_LOG_DIR}/error.radio.log
    CustomLog ${APACHE_LOG_DIR}/access.radio.log combined

    ProxyPass "/"  "http://localhost:8080/"
    ProxyPassReverse "/"  "http://localhost:8080/"

    <Directory /var/www/radio/>
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

Ansible role

# clone this project
git clone https://github.com/segler-alex/radiobrowser-api-rust.git
cd radiobrowser-api-rust
# checkout stable
git checkout stable
# deploy, change email adress, for ssl with certbot

Building

Distribution tar.gz

./builddist.sh

Debian/Ubuntu package

cargo install cargo-deb
cargo deb # run this in your Cargo project directory

With docker

Generate deb and tar.gz distribution with the help of docker. This has the following upsides:

  • platform independent builds
  • clean builds
docker run -w /root -v $(pwd):/root ubuntu:bionic bash build_with_docker.sh

Kubernetes helm chart

There is a helm chart at https://gitlab.com/radiobrowser/helm-charts

Development

Run a test environment in multiple shells

# 1.Shell: start db
docker run -e MYSQL_DATABASE=radio -e MYSQL_USER=radiouser -e MYSQL_PASSWORD=password -e MYSQL_RANDOM_ROOT_PASSWORD=true -p 3306:3306 --rm --name dbserver mariadb --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
# 2.Shell: start radiobrowser with local config
cargo run -- -f radiobrowser-dev.toml

# 3.Shell IF NEEDED: check content of database directly
docker exec -it dbserver bash
mysql -D radio -u radiouser -ppassword

Environment vars / parameters
