Docker configuration for Flarum

Justoverclock

Guys, i've created a container for Flarum by myself, just to learn something.

my steps.

Create empty folder and launch a new project for flarum composer create-project flarum/flarum .
Create a Dockerfile with necessary config

FROM php:8.1-apache

# Install necessary extensions
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
        libzip-dev \
        unzip \
        && docker-php-ext-configure gd --with-freetype --with-jpeg \
        && docker-php-ext-install -j$(nproc) gd pdo pdo_mysql zip

# Enable Apache mod_rewrite
RUN a2enmod rewrite

# Set up Flarum
RUN mkdir /var/www/flarum
COPY . /var/www/flarum
RUN chown -R www-data:www-data /var/www/flarum/storage

# Set up Apache
COPY apache.conf /etc/apache2/sites-available/000-default.conf

RUN chown -R www-data:www-data /var/www/flarum \
    && chown -R www-data:www-data /var/www/flarum/public/assets

WORKDIR /var/www/flarum

Create a docker-compose.yml file with my config

version: "3"

services:
  db:
    image: mariadb
    restart: always
    environment:
      MYSQL_DATABASE: flarum
      MYSQL_USER: flarum_user
      MYSQL_PASSWORD: flarum_password
      MYSQL_ROOT_PASSWORD: root_password
    volumes:
      - db_data:/var/lib/mysql
  web:
    build:
      context: .
      dockerfile: Dockerfile
    restart: always
    ports:
      - "8000:80"
    depends_on:
      - db
    environment:
      DB_HOST: db
      DB_DATABASE: flarum
      DB_USERNAME: flarum_user
      DB_PASSWORD: flarum_password

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    restart: always
    ports:
      - "8081:80"
    depends_on:
      - db
    environment:
      PMA_HOST: db
      MYSQL_ROOT_PASSWORD: example

volumes:
  db_data:

but i have a problem here (sorry is my really first attempt). i can't use files that are in my folder.
how can i use my flarum files into my folder?

For example, if I need to modify composer.json I need to do that from
Docker terminal inside the var/www folder

gnorato

hello. If you are working with docker you must create a persistent volume for flarum /flarum/app since when you restart or recreate the container it will try to install everything and will not keep your information.
Once you have created the persistent volume, place it in the docker-compose just like you did for the database.
Hay proyectos flarum en github para usar con docker que ya tienen los compuestos listos.

gnorato i'm trying but i can't find a solution, an help will be appreciated

Justoverclock check out these links about Volumes and let me know if you don't understand something:

https://docs.docker.com/storage/volumes/
https://towardsdatascience.com/the-complete-guide-to-docker-volumes-1a06051d2cce
https://earthly.dev/blog/docker-volumes/

luceos

your web is missing the volume

Justoverclock

ok, now i can run the container, i've set up a volume for web also....but if i install a new extension in the root folder, i need to restart the container to see the extension...and if i enable the extension, i can't see changes in the frontend even if the extension is enabled...

🙁

luceos

Justoverclock use delegated.

Justoverclock

luceos seems that everything i do....i cannot see extensions enabled in frontend....only enabled in backend

probably...i'll go for xampp again.....sad because i prefer docker as a solution

jslirola

Justoverclock could you share your Dockerfile and docker-compose.yml?

I see that you have a version published in your first message but I don't know if it is up to date.

I use this link for my flarum with docker and all fine. I not should restart flarum When install an extensión.

@Justoverclock Is your Docker environment already working after the publication of luceos's code? I have tried to run your files out of curiosity but it gave me an error not finding the Nginx configuration file. If everything goes well for you, I wont continue testing, otherwise let me know to find the problem.

Justoverclock

jslirola I cant see nothing with my previous code…he can’t find nginx for me also

jslirola

Justoverclock okay. So we found the main problem 🙂

Once you write the file (Dockerfile) to configure the containers, you should check the logs to make sure you don't get any errors and copy the basic dependencies of the services. In this case, you are trying to mount an Nginx server without its main configuration file.

Copy this one to your root folder to continue with the process:
https://github.com/zgq354/flarum-docker-env/blob/master/nginx/conf/nginx.conf

It's an example that will eliminate your problem, but you'll probably need to modify the content as you prefer.

Since I assume you want to continue learning, run this command to build the containers and you will find the following challenge on your way:

docker-compose build --no-cache

Spoiler:

Justoverclock

jslirola thx!!!!!! sorry but i'm really new with docker...

jslirola

Justoverclock Don't worry, you are learning and at first it is common to need help. 👍
