Docker environment for a Symfony5 project
==================================

# Add to your project

Move the `docker-compose.yml` and the folder named `docker_build` containing nginx and php-fpm config for it to the root of your Symfony project.

Ensure the webserver config on `docker\nginx.conf` is correct for your project. For instance, for Symfony 4 or 5 it should look for the `public/index.php`, instead of the `web/app.php` from Symfony2 and Symfony3

Note: you may place the files elsewhere in your project. Make sure you modify the locations for the php-fpm dockerfile, the php.ini overrides and nginx config on `docker-compose.yml` if you do so.

# How to run

Dependencies:

  * Docker engine v1.13 or higher. Your OS provided package might be a little old, if you encounter problems, do upgrade. See [https://docs.docker.com/engine/installation](https://docs.docker.com/engine/installation)
  * Docker compose v1.12 or higher. See [docs.docker.com/compose/install](https://docs.docker.com/compose/install/)

Once you're done, simply `cd` to your project and run `docker-compose up -d`. This will initialise and start all the containers, then leave them running in the background.

# 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 }}')`

# My installation

* Build containers: `docker-compose build`
* Run containers: `docker-compose up -d`
* 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/.* . && rm -Rf 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`

## Let's go !

* Let's create first object:
   * 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`
