Environnement de développement Docker pour démarrer un nouveau projet Symfony5

Présentation

L'objectif de ce dépôt est de proposer et de faire évoluer une configuration de départ pour démarrer très simplement un nouveau projet Symfony dans des conteneurs Docker.

En suivant pas-à-pas les instructions à partir du chapitre "Installation", on peut démarrer en quelques minutes un nouveau projet.

Le dépôt utilise plusieurs branches qui peuvent être utilisée selon le point de départ recherché:

1. la branche docker_config fournit juste le docker-compose.yml et les Dockerfile qui permettent de construire les conteneurs ;
2. la branche master fournit la structure de départ du projet Symfony ;
3. la branche with_vujs permet de démarrer le projet en complémentarité du framework Javascript VueJS ;

Installation

• Build containers: docker-compose build
• Run containers: docker-compose up -d
• Manually change owner of app dir (temp): sudo chown 1000:1000 app/
• Enter in php container docker-compose exec --user 1000 php bash
  • Install Symfony: composer create-project symfony/skeleton symfony
  • Move project in parent (app): mv symfony/* . && mv symfony/.* . ; rmdir symfony
  • Add Symfony requirements:

  composer require annotations
  composer require --dev profiler
  composer require twig
  composer require orm
  composer require form
  composer require form validator
  composer require maker-bundle
  composer require security-csrf
  

• Stop containers: docker-compose down
• Adapt querystring in ./app/.env:

  --- DATABASE_URL="postgresql://db_user:db_password@127.0.0.1:5432/db_name?serverVersion=13&charset=utf8"
  +++ DATABASE_URL="postgresql://postgres:secret@db:5432/postgres?serverVersion=12&charset=utf8"
  

• Run containers: docker-compose up -d
• Enter in php container docker-compose exec --user 1000 php bash
  • Test psql connection: psql --host db --user postgres --password postgres
  • Create database schema: bin/console doctrine:schema:create

C'est parti !

• Créons un premier objet:
  • Create entity: bin/console make:entity Beer
  • Create CRUD on entity: bin/console make:crud Beer
  • See sql: bin/console doctrine:schema:update --dump-sql
  • Control migrations: bin/console doctrine:migrations:status
  • Generate migration file: bin/console doctrine:migrations:diff
  • See migration file: cat migrations/Version20210218160541.php
  • Migrate: bin/console doctrine:migrations:migrate
  • Control migrations: bin/console doctrine:migrations:status
  • ...

Docker compose cheatsheet

Note: you need to cd first to where your docker-compose.yml file lives.

• Start containers in the background: docker-compose up -d
• Start containers on the foreground: docker-compose up. You will see a stream of logs for every container running.
• Stop containers: docker-compose stop
• Kill containers: docker-compose kill
• View container logs: docker-compose logs
• Execute command inside of container: docker-compose exec SERVICE_NAME COMMAND where COMMAND is whatever you want to run. Examples:
  • Shell into the PHP container, docker-compose exec --user 1000 php bash
  • Run symfony console, docker-compose exec --user 1000 php bin/console
  • Open a postgresql shell, docker-compose exec --user postgres db psql
    • or if user is not postgres: docker-compose exec db psql --user admin postgres

Docker general cheatsheet

Note: these are global commands and you can run them from anywhere.

• To clear containers: docker rm -f $(docker ps -a -q)
• To clear images: docker rmi -f $(docker images -a -q)
• To clear volumes: docker volume rm $(docker volume ls -q)
• To clear networks: docker network rm $(docker network ls | tail -n+2 | awk '{if($2 !~ /bridge|none|host/){ print $1 }}')
