kolaente/polr repository overview

⁠Polr Docker Image

Made with Alpine, NGINX and PHP 7.

This is an unofficial Dockerimage for the Polr URL Shortener⁠.

⁠Usage

Simply run

docker run -p 80:80 -d kolaente/polr

The Container needs another DB-Container which holds the database. You can use MariaDB⁠/Mysql⁠.

⁠Volumes

The container has one volume:

• /var/session. Holds PHP session data. Very useful when using a loadbalancer with mutliple instances of Polr.

⁠Docker-Compose

Probably the easiest way to run the image is by using docker-compose⁠:

Note: You really should change MYSQL_ROOT_PASSWORD when running in production!

version: '2'
services:
  app:
    image: kolaente/polr
    restart: always
    ports:
      - "8080:80"
    depends_on:
      - db
    volumes: # Save the config
      - ./.env:/var/www/.env
  db:
    restart: always
    image: mariadb
    environment:
      - MYSQL_ROOT_PASSWORD=changeme #CHANGE THIS!
      - MYSQL_DATABASE=polr
    volumes:
      - ./db/:/var/lib/mysql

Afterwords, install Polr by pointing your browser to server_url/setup and input the nessesary fields. For DB-Host, use db
