make:docker:database

Video not working?

It looks like your browser may not support the H264 codec. If you're using Linux, try a different browser or try installing the gstreamer0.10-ffmpeg gstreamer0.10-plugins-good packages.

Thanks! This saves us from needing to use Flash or encode videos in multiple formats. And that let's us get back to making more videos :). But as always, please feel free to message us.

Doctrine is installed! Woo! Now we need to make sure a database is running - like MySQL or PostgreSQL - and then update the DATABASE_URL environment variable to point to it.

30 lines .env
... lines 1 - 27
DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name?serverVersion=5.7
... lines 29 - 30

So: you can absolutely start a database manually: you can download MySQL or PostgreSQL onto your machine and start it. Or you can use Docker, which is what we will do. OooOoooo.

Using Docker?

Now, hold on: if you're nervous about Docker... or you haven't used it much... or you used it and hated it, stay with me! Using Docker is optional for this tutorial, but we're going to use it in a very lightweight way.

The only requirement to get started is that you need to have Docker downloaded and running on your machine. I already have Docker running on my machine for Mac.

Docker is all about creating tiny containers - like a container that holds a MySQL instance and another that holds a PHP installation. Traditionally, when I think of Docker, I think of a full Docker setup: a container for PHP, a container for MySQL and another container for Nginx - all of which communicate to each other. In that situation, you don't have anything installed on your "local" machine except for Docker itself.

That "full Docker" setup is great - and, if you like it, awesome. But it also adds complexity: sharing source code with the containers can make your app super slow - especially on a Mac - and if you need to run a bin/console command, you need to execute that from within a Docker container.

Our Simple Docker Plan

And so, instead, we're going to do something much simpler. First, we are going to have PHP installed on our local machine - I do have PHP installed on my Mac. Then, we're just going to use Docker to launch services like MySQL, Redis or Elasticsearch. Finally, we'll configure our local PHP app to communicate with those containers.

For me, it's kind of the best of both worlds: it makes it super easy to launch services like MySQL... but without the complexity that often comes with Docker.

Hello make:docker:database

Ok, ready? To manage our Docker containers, we need to create a docker-compose.yaml file that describes what we need.

Tip

If you're using the latest version of Symfony Flex, then when you ran composer require orm, it asked you if you wanted Docker configuration. If you answered yes, congrats! You can skip this step because you already have a docker-compose.yml file with a database service inside. Skip ahead to around 4:30 when we run docker-compose up.

That file is pretty simple but... let's cheat! Find your terminal and run:

php bin/console make:docker:database

This command comes from MakerBundle version 1.20... and I love it. A big thanks to community member Jesse Rushlow for contributing this!

Ok: it doesn't see a docker-compose.yaml file, so it's going to create a new one. I'll use MySQL and, for the version - I'll use latest - we'll talk more about that in a few minutes.

And... done! The database service is ready!

Well, in reality, the only thing this command did was create a docker-compose.yaml file: it didn't communicate with Docker or start any containers - it just created this new docker-compose.yaml file.

version: '3.7'
services:
database:
image: 'mysql:latest'
environment:
MYSQL_ROOT_PASSWORD: password
ports:
# To allow the host machine to access the ports below, modify the lines below.
# For example, to allow the host to connect to port 3306 on the container, you would change
# "3306" to "3306:3306". Where the first port is exposed to the host and the second is the container port.
# See https://docs.docker.com/compose/compose-file/#ports for more information.
- '3306'

And... it's pretty basic: we have a service called database - that's just an internal name for it - which uses a mysql image at its latest version. And we're setting an environment variable in the container that makes sure the root user password is... password! At the bottom, the ports config means that port 3306 of the container will be exposed to our host machine.

That last part is important: this will make it possible for our PHP code to talk directly to MySQL in that container. This syntax actually means that port 3306 of the container will be exposed to a random port on our host machine. Don't worry: I'll show you exactly what that means.

docker-compose up

So... yay! We have a docker-compose.yaml file! To start all of the containers that are described in it... which is just one - run:

docker-compose up -d

The -d means "run as a daemon" - it runs in the background instead of holding onto my terminal.

The first time you run this it will take a bit longer because it needs to download MySQL. But eventually.... yes! With one command, we now have a database running in the background!

So... how do we communicate with it? Next, let's learn a bit more about docker-compose including how to connect to the MySQL instance and shut down the container.

Leave a comment!

Yo @ashatou!

Yikes! That's an ugly error! This appears to be a bug in DoctrineBundle when used with php 8.1 and it was fixed in DoctrineBundle 2.4.3 - https://github.com/doctrine/DoctrineBundle/issues/1377

Unfortunately, upgrading the code from this project to that version of DoctrineBundle isn't as simple as a "composer update". I just checked, and to get compatible versions of everything, a bunch of things need to be updated, including (at least) parts of Symfony itself and the doctrine-extensions library.

I'd recommend checking out our new Symfony 6 Doctrine tutorial. Or, you can definitely use this downloaded code - but upgrade Symfony to version 5.4 and then running composer update. To do this, you'd replace all of the 5.1.* with 5.4.* in composer.json and then run composer update. When I tried that on the "finish" code just now, it allowed DoctrineBundle to upgrade and the error went away on PHP 8.1 :).

Cheers!

Hey,

I'll leave a comment to help anyone who takes this course and encountered this error after running make:docker:databas:

Could not check compatibility between Symfony\Bridge\ProxyManager\LazyProxy\PhpDumper\LazyLoadingValueHolderGenerator::generate(ReflectionClass$originalClass, Zend\Code\Generator\ClassGenerator $classGenerator):
void and ProxyManager\ProxyGenerator\LazyLoadingValueHolderGenerator::generate(ReflectionClass $originalClass, Laminas\Code\Generator\ClassGenerator $classGenerator),because class Zend\Code\Generator\ClassGenerator is not available in/home/nathan/dev/plateforme/facturation/vendor/symfony/proxy-manager-bridge/LazyProxy/PhpDumper/LazyLoadingValueHolderGenerator.php on line 33

Upgrading to symfony 5.3 fixed the problem, in order to do that you've got to update symofny as well as it's packages.

Head to composer.json and under "require:" change versions from 5.0.* (for all packages) to 5.3.* plus under "extra" change symfony version to 5.3.*

Code linked here works perfectly fine with symfony 5.3

However I can't get the reason, why you got such an error? I tested this course and it shouldn't be here at all =)

Sadly enough for what I am willing to do Docker is not an option I am willing to pay for. It would be appreciated that solutions get provided for common usecases like xampp and mamp

For those who don't want to use Docker and use xampp


# config/packages/doctrine.yaml
dbal:
override_url: true
url: '%env(resolve:DATABASE_URL)%'

driver: 'pdo_mysql'
server_version: '5.7'
charset: utf8
unix_socket: /Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
default_table_options:

collate: utf8_general_ci

And if you use mapp
change the unix_socet: to


unix_socket: /Applications/MAMP/tmp/mysql/mysql.sock

Hey Pieter-jan C.!

I'm really sorry you're unhappy - and I don't blame you :/. We need to do better. I did try to mention how things would be done without Docker, but clearly, I was too vague about that. Tahnks for posting your solution here. Most people (but not all!) will not need to mess with the unix_socket thing (I'm mentioning this for the benefit of others) - most PHP installs will already be looking in the correct place for it.

Well ok, but how many people will use docker on a live website? Most use cases will be a localy run db. All fun and games but docker costs money as soon as you want a private db, and i believe that anyone who wants a website online wants a private one :D. So maybe a idea. Make a video or 2 to explain a setup for a local db?

Reply

Hey Pieter-jan C.!

> Make a video or 2 to explain a setup for a local db?

We definitely need to do that :) - at least the basics so people can choose to run Docker locally if they want to.

> Well ok, but how many people will use docker on a live website? Most use cases will be a localy run db.

I completely agree! I mean, there are many people who do use in on production, but this chapter is *all* about using Docker locally as a development tool - it has nothing to do with using it on a live site. But maybe that also was unclear? I'd appreciate the feedback if that part was confusing as well.

Anyways, thanks for the conversation - I chatted about your feedback so far with the team earlier today :).

Cheers!

It looks like docker-compose down will destroy the container and the db, vs. stop which will allow it to persist?

How would you add a named volume to the docker-compose.yaml?

Jesse-Rushlow Avatar Jesse-Rushlow | SFCASTS | brianbarrick | posted 1 year ago

Howdy Brian!

When you run docker-compose down it will destroy all of the containers, the docker network those containers use, and any data within the containers (e.g. the database) that are defined in the docker-compose.yaml. If you run docker-compose stop, all of the containers are preserved (including the data within them) but are "turned off". Think of it as turning off you laptop, docker-compose stop would turn off your laptop until you were ready to fire it back up. docker-compose start database would turn it back on again.

In regards to volumes, assuming your docker-compose.yaml is in your projects root directory, you can add volumes to the container(s) by editing your docker-compose.yaml file as follows.


// docker-compose.yaml

services:
database:
image: 'postgres:latest'
...
volumes:
- ./relative-path-on-host:/abusolute-path-in-container

The above code would add two separate volumes to your container. As a word of caution - when using volumes, the docker container has read/write access to the data on the host and vice versa. If you were to delete a file from within the container, it would also be removed from the host (assuming file permissions were allowed). However, docker-compose down would not destroy the data within the volume on the host.

For database containers, if you want to preserve a modified database configuration using the native configuration files, you can add a volume to the container as follows. This assumes you have created a .data/config directory within your project. The host directory name / location can be anywhere.


// MySql / MariaDB
- ./.data/config:/etc/mysql

// Postgres
- ./.data/config:/usr/share/postgresql

For the actual database data itself, you would add a volume like:


// MySql / MariaDB
- ./.data/var:/var/lib/mysql

// Postgres
- ./.data/var:/var/lib/postgres/data

A complete MySQL example with configuration and data volumes on the host:


services:
database:
image: 'postgres:latest'
...
volumes:
- ./.data/config:/etc/mysql
- ./.data/var:/var/lib/mysql

I hope this helps! If you have anymore questions - feel free to ask!

Thanks
Jesse

I get this error:
ERROR: Version in "./docker-compose.yaml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

my installed version is 3.7.
any ideas?

If you run docker-compose --version what version do you see? If it's 3.7 then it should run but for some other reason it isn't. Try upgrading docker-compose and see if it fixes the problem.

> I think he didn't do good job in this lecture...

Well, that's not so easy to achieve and especially because this is not a Docker tutorial. There're many OS with many possible setups, it would take a lot of time explaining how to install Docker and how to fix errors but thanks for your feedback we take into account messages like this one so we can improve our tutorial-making process.

Hey @Farry7!

The docker-compose version stuff is confusing:

> Docker Compose version file 3 was introduced in release 1.10.0 of Docker Compose and 1.13.0 release of Docker Engine

So basically, the "version: 3" in the docker-compose.yaml file is not referring to the version of docker-compose itself (I know, confusing) - but a bit more about "version 3 of the docker-compose API". But, your version - 1.27.4 - does tell us that it is plenty new enough to support version 3 (and also version 3.7... because you have the absolute newest version of docker-compose). It's also very likely that your Docker engine is new enough to support version 3.7 - it requires version 18.06.0+.

Are you getting a version that the docker-compose version is not supported by your Docker? If so, then probably your Docker Engine is too old... but you can also probably change the version to 3.0 in your docker-compose.yaml file - I don't believe we really use any "new" features in that file that require 3.7 (but I'm not 100% sure).

Anyways, let me know what you're seeing and we'll try to help - sorry for the troubles!

Hey there!

Sorry about the troubles - we appreciate the feedback! Honestly, for some people Docker is the best thing ever. For others, it’s an unnecessary pain. That’s actually why we (A) make it an optional part of this tutorial and (B) we use a, kind of, “light” integration with Docker.

Anyways, skip Docker! And if you any trouble with the database config part, please let us know :).

Better late then never, bet try the DATABASE_URL without quotes, i.e.

DATABASE_URL=mysql://root:MY_PASSWORD@localhost:3306/db_name?serverVersion=5.7

That worked for me, somehow my system does not like the variable inside double quotes...

I think the sudo may have been a factor here as well. You should not have to use sudo for any of the Symfony console commands.

Reply

Hey Maike L.!

Hmm. The "Connection refused" usually means that the database isn't running... or that there is some other problem. It's... unfortunately, kind of a "generic" MySQL error that could mean a lot of things :/. Are you able to use the same connection parameters in, for example, some MySQL client like TablePlus https://tableplus.com/ to connect? Also, try 127.0.0.1 instead of localhost. That usually does not make any difference, but it can in some edge cases. Btw, I can tell you for sure the problem is not aa bad password of anything like that - it's some sort of connection error to the server.

Cheers!

Hi there there ,
I would like to point out a problem, that may stop some windows users from using docker.
I have a bunch of vagrant boxes (using oracle vm virtualbox) for local developement on different projects.
Docker requires hyper-v to be activated, but on the other side Virtualbox hyper-v support is still experimental and in my case it causes a major performance issue that prevents me from working with vagrant.

Anyway, I will switch to my notebook, so i can follow along with your tutorial.

it by default a linux container but i never made it to start docker , so i switched to windows container because i am using windows 10 pro it worked

Hey, thanks for this tutorial.

In the .env file of the course source code is defined 'DATABASE_URL=...?serverVersion=5.7' but the version installed by Docker seems to be 8.0, the serverVersion needs to match the actual MySQL version installed ?

Hey Tavo

That's a great question and technically yes, you should update the DATABASE_URL env var to match your database connection but in the next chapters you'll learn why, while using Symfony's webserver, you don't have to do that

So.. the only place I do have to replace the environment variables is while I'm running tests (env.test file) ? I'm not sure I understand how the config of the test database would be if I have a specific database for testing and another one for the dev environment.

Reply

How you deal with environment variables depends on your server. If you're running, let's say, on Apache, you can configure your host to set the values of the env vars you need. That would be a way to do it but Symfony gives you another way, through the .env file. In theory, you should have one file for your production/development environment, and another one for the testing environment .env.test. So, inside .env.test you have to configure the DATABASE_URL variable to point to your test database, and that's it.
