contao-docker-test

#Installation:

• Go to “.docker/contao” folder and create docker containers: docker-compose up -d
• Create a database for contao in database container:
  • One way to do so is to open up the “Database”-Tab of PhpStorm
    • Click on “+” -> Data Source -> MariaDB
    • Add a name to configuration e.g. contao-db
    • Host: localhost
    • Port: 3306
    • User: root (according to database-service in docker-compose.yml)
    • Password: root (according to database-service in docker-compose.yml)
    • Once you’re connected go to Query Console (icon at the top “QL”) and create the database for contao
      • Enter the following line into the console and press the “play”-button to execute the query:
      • CREATE DATABASE contao CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
      • The database name is free to chose but in this example the database name ‘contao’ is being used
  • Another way is to connect to phpmyadmin via localhost:8080 as it’s configured in docker-compose.yml
• Open contao manager in browser after database creation in order to install contao
  • Step through the installation process until you get to enter the database credentials
  • NOTE: the ‘host’ isn’t ‘localhost’ here, use the name of the database service ‘database’ as it’s configured in the docker-compose.yml
  • Finish the installation and have fun :)
  • Contao will be available here: http://localhost/contao

Some important information

• The database content is stored in a container which is bind-mounted to the ‘db’-folder of the project
• If you should renew your containers, make sure you don’t delete this folder, since all database data is contained in there
• Even if the container will be removed, the database data still exists in this folder and the data will be provided for the database container through the bind-mounting if you create a new database container
• If you want to export the database, either do it via phpmyadmin or enter the container and use mysql dump
• To enter a container e.g. the contao container run docker exec -it contao /bin/bash.
  • After this you’re directly within the container and can browse through it’s content via console.
  • If you did changes e.g. in the composer.json on your host machine (your computer - not within a container) to install or update bundles, then run e.g. composer install within the container
  • If you do changes on you host machine, these changes will be also available for the container via bind-mounting
• To exit the container, simply run exit and you’ll get back to the console of your host machine ;)
