Ahora tenemos una base de datos Postgres ejecutándose dentro de un contenedor Docker. Podemos verlo ejecutando:
docker-compose ps
Esto también nos dice que si queremos hablar con esta base de datos, podemos conectarnos al puerto50739 en nuestra máquina local. Ese será un puerto diferente para ti, porque se elige al azar cuando iniciamos Docker.
También hemos aprendido que podemos hablar con la base de datos directamente a través de:
docker-compose exec database psql --user symfony --password app
Para conseguir que nuestra aplicación real apunte a la base de datos que se ejecuta en este puerto, podríamos entrar en .env o .env.local y personalizar DATABASE_URLen consecuencia: con el usuario symfony la contraseña ChangeMe... y con el puerto que tengas actualmente. Aunque... tendríamos que actualizar ese puerto cada vez que iniciemos y detengamos Docker.
El Binario de Symfony y variables de entorno de Docker
Afortunadamente, no tenemos que hacer nada de eso porque, sorpresa, ¡la variable de entorno DATABASE_URLya está correctamente configurada! Cuando configuramos nuestro proyecto, iniciamos un servidor local de desarrollo utilizando el binario de Symfony.
Como recordatorio, voy a ejecutar
symfony server:stop
para detener ese servidor. Y luego reiniciarlo con:
symfony serve -d
Menciono esto porque el binario symfony tiene un superpoder de Docker bastante impresionante.
Observa: cuando actualices ahora... y pases el ratón por la esquina inferior derecha de la barra de herramientas de depuración de la web, dirá "Env Vars: De Docker".
En resumen, ¡el binario de Symfony se dio cuenta de que Docker se estaba ejecutando y expuso algunas nuevas variables de entorno que apuntaban a la base de datos! Te lo mostraré. Abrepublic/index.php. Normalmente no nos preocupamos por este archivo... pero es un buen lugar para volcar algo de información justo cuando nuestra aplicación empieza a arrancar. Dentro de la llamada de retorno,dd() la superglobal $_SERVER. Esa variable contiene mucha información, incluyendo cualquier variable de entorno.
Bien, gira y actualiza. ¡Una gran lista! Busca DATABASE_URL y... ¡ahí está! Pero ese no es el valor que tenemos en nuestro archivo .env: el puerto no es el que tenemos ahí. No, ¡es el puerto correcto necesario para hablar con el contenedor Docker!
Sí, el binario de Symfony detecta que Docker se está ejecutando y establece una variable de entorno realDATABASE_URL que apunta a ese contenedor. Y recuerda que, al tratarse de una variable de entorno real, ganará a cualquier valor colocado en los archivos .env o .env.local.
La cuestión es que, con sólo iniciar Docker, ya está todo configurado: no hemos tenido que tocar ningún archivo de configuración. Eso está muy bien.
Por cierto, si quieres ver todas las variables de entorno que configura el binario de Symfony, puedes ejecutarlo:
symfony var:export --multiline
Pero por mucho la más importante es DATABASE_URL.
Bien: ¡Doctrine está configurado! A continuación, vamos a crear la base de datos propiamente dicha mediante un comando bin/console. Cuando lo hagamos, aprenderemos un truco para hacerlo con las variables de entorno del binario de Symfony.

Hey @Lore
I strongly recommend installing Symfony CLI, it will make your life way easier, but if for some reason that's not possible, you'll have to go with ling's approach
Cheers!

Thanks, I've already installed Symfony CLI, launched the 'docker-compose up -d' command, and subsequently, the 'symfony serve -d' command, but in the debug toolbar, 'docker compose' shows 'down,' and 'Env var' shows 'none.'

That's unexpected, Symfony CLI should detect your Docker configuration automatically. Check two things
1) Your Symfony project is using Symfony Flex. You should see symfony/flex inside your composer.json file
2) Your docker-compose.yaml file should be at the root of your project, otherwise you need to set up a few env vars as explained here https://symfony.com/doc/current/setup/symfony_server.html#docker-integration

Hey @ling
Yeah, you can just use .env files to configure your environment. But why you can't use the symfony binary with docker detection?
Cheers!

I don't know, it just doesn't hook up naturally. I followed all the steps of the tutorials i believe. Not sure why it's not working. I could follow the two previous courses without any problem, this is the first time the code doesn't seem to work as it does in the video. When i hover on the right-bottom corner of the debug bar, it says that docker-compose is down, and next to ENV variables it shows: NONE. But i have a docker container with psql in it, and i ran symfony serve. Mystic?

I guess something is wrong with docker detection, is it the latest version? Which console is used to run docker? Symfony binary? I'm asking because I had same issues when tried to run docker from the PHPStorm console, and for me, it works if I run docker from the native MacOS console or from the docker desktop app.

I'm using Docker desktop version 4.19.0.
I start the project with docker:
docker compose up -d
Then the symfony server:
symfony serve -d
[OK] Web server listening
The Web server is using PHP FPM 8.2.5
https://127.0.0.1:8000
The opening the website at https://127.0.0.1:8000, the bottom right corner of the debug bar shows:
sf 6.2.12, and opening the sf server hover menu, i still have:
- docker compose: down
- env vars: none
which is easily fix by setting the correct port for the DATABASE_URL variable in an env.local file as mentioned in a video of the tutorial.
So i'm not sure where the problem is exactly, but the workaround is fine by me as i just wanted to complete the tutorial, knowing that in prod env there are always other things we can do to setup env variables...

Sorry for long waiting, I tried to debug, different environments, but I can't reproduce this situation, so probably I don't have any solution for it. Looks like Symfony binary just didn't catch docker instance to get all env vars

Hey SymfonyCast-Team,
I am facing the same issue. Not only with the downloaded code of the course, but also with a fresh installation.
- fresh installation of docker desktop (incl. reinstallation)
- creation of new project with
symfony new docker_postgresql_test --webapp - starting docker with
docker-compose up - checking docker with
docker-compose ps--> [postgreSQL-Server running] - checking postgreSQL with
docker-compose exec database psql app app--> [login successful] - starting web-server with
symfony serveorsymfony server:start -d--> [https://127.0.0.1:8000/ is working] - Symfony Profiler has
docker compose: downandenv vars: none
HEADS-UP: I realized a difference in
SYMFONY_DOCKER_ENV-variable. The value is "1" in the video, but NULL on my system. I tried to update it in.env-file without success.

Hello,
I thank you immensely for the solution provided. I had the same issue and despite various attempts, I had been stuck on it for several days. I really did not want to resort to using a local database. For your information, I am also using MacOS and the same version of Docker Desktop as you, and we are not the only ones experiencing this issue.

Another solution (worked for me) - change file names:
from: compose.yaml to: docker-compose.yaml
and from: compose.override.yaml to docker-compose.override.yaml

Yea, this is a good tip! The latest version of the recipe ships with compose.yaml instead of docker-compose.yaml. The compose.yaml filename is the new filename you should use with Docker. But if you have a slightly out-of-date version of Docker, then it won't recognize it at all. This is definitely a bit of a gotcha right now!

I figured it out - it was "symfony-cli" outdated.
(Because I had it in two versions in different places, I didn't notice that the upgrade didn't work. After removing it from everywhere and reinstalling symfony-cli, the problem with Docker is solved).
Hey!
I faced the same problem with Symfony binary variables and Docker on my Ubuntu machine. And after some searching on the Internet, I realized that there was a problem with the docker command. When I used the "docker compose up -d" command, the container appears in Docker Desktop, but Symfony could not recognize this connection. So, I used "docker-compose" command instead, and it's started to work like a charm (but there wasn't a container visiable in Docker Desktop).
It's important to note, that you should disable the alias option in Docker Desktop settings (Settings -> General -> Enable 'docker-compose' CLI alias), otherwise there will be no effect.

Hey @bam1to ,
Thanks for sharing this tip with our Docker friends! Also, don't forget to execute symfony console instead of bin/console when using Docker to avoid connection problems.

Hello, having issues making Symfony see my docker.
Symfony is running. Docker is running.
But when I open localhost server does not see my database running and DATABASE_URL port is not changed...
Not sure what is the issue
Docker version 20.10.17, build 100c701
Using Ubuntu
In next tutorial video I tried running: ./bin/console doctrine:database:create
And I got this: An exception occurred in the driver: could not find driver

Hey Algirdas,
When you use Docker + Symfony, you got to run any commands through the Symfony CLI. For example symfony console doctrine:database:create or to spin up the web server symfony serve -d
I hope it helps. Cheers!

Hey @ling
It has a few subtle differences. If you use Docker, you can execute your commands through Symfony CLI to let it set up all of the env vars. Also, you can configure what PHP version you want to use per project, you can read more about it here: https://symfony.com/doc/current/setup/symfony_server.html#selecting-a-different-php-version

I don't have this super power of symfony console directly creating the docker friendly ENV vars.
I'm using php FPM 8.2.5 and symfony 6.1.2 (on Mac 12.6.6).
Don't know if it's normal (i.e., a change in symfony or doctrine behaviour with the newer versions), or if it's specific to my computer, but in the meantime i'll just create an .env.local file with DATABASE_URL using the correct docker port, hoping that it will do for the rest of this course.
Here is my compose.json in case it helps:
