Docker y variables de entorno

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:

Same problem

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.

Cheers

Not sure how closely your issues are related to mine.
But if it helps, here is my final composer.json (i fought a lot with it because some tools in the whole tutorial had some compatibility issues):

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...

hm Symfony binary version?

$ php bin/console --version
Symfony 6.2.12 (env: dev, debug: true) #StandWithUkraine https://sf.to/ukraine

nope, the binary version symfony version ?

$ symfony version
Symfony CLI version 5.5.6 (c) 2021-2023 Fabien Potencier #StandWithUkraine Support Ukraine (2023-05-16T13:26:30Z - stable)

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

Cheers

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!

Is there any difference between using
php bin/console and symfony console
? Or is it exactly the same ?

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

Cheers!

Hi, so not sure what fixed it. Today I tried launching and had issues connecting to database not to mention the issue I already had. Reinstalled postgresql on my machine and now it works

Hey Algirdas!

Weird! Database gremlins hiding somewhere :). Anyways, I'm glad it's behaving for you now!

Cheers!

Hi,
are you planning to make a video on how to dockerise the full app ie database + php + web server ?

I am struggling with docker configs

Hey mofogasy

There is no plan to make a tutorial about it soon but thank you for telling us what you would like to learn. We take in consideration all feedback when we select the topic of the next tutorial

Thanks!
