Thanks for sharing, great stuff!!

I think after the "One last update to add to our nginx service definition" after the ports, the indentation is a little bit broken.

Hello,
Thank you for supporting us !
The indentation is now fixed.

Thanks for this post!
It helped me a lot, I'm new to both symfony & docker, I'm using symfony 3.4 with skeleton which uses the 'public' folder, but it can't load the css files =/.

[the-necroposter]

Antoine Lelaisant 11/30/2018

Hello Tom !
May I suggest you to look at Webpack Encore https://symfony.com/doc/3.4... which is a library developed by Symfony and that allows to compile and copy your project css and js files into the 'public' folder. As soon as your assets are stored in the 'public' folder nginx should be able to load them properly.

Very useful post!

After following each step of this tutorial I wanted to create a symfony 4 project from the scratch by launching "composer create-project symfony/skeleton projectFolder" inside the php container. The fact is that there is no way and I get permission problems to create new files/directories. When I launch "id" inside the container I get "uid=1000 gid=1000 groups=1000 I have no name!" it seems that the user root is the one who is creating files inside the container.

Very appreciated if you can help me out with this!

Regards.

I had the same issue. I'm working on Mac, and what I did was removing user: 1000:1000 from docker-compose.yml

[the-necroposter]

Dennis de Best 6/11/2019

I ended up adding
RUN adduser -home /home/exploit exploit -u 1000

to the php Dockerfile and now everything seems to work correctly

Great stuff, guys, thanks!

What puzzles me, and I even checked a few repos of lcouellan, is that you simply install mysql 8 from image, and it works? How do you handle this new auth plugin it comes with? Adminer does not even able to connect it by default. I looked around and found hacks copying extra my.cnf files with default_authentication_plugin set to mysql_native_password. How is it that you don't have to deal with this? :)

My other question is regarding speed. I follow Ryan's Sf4 tutorial course at KnpU (now SfC, I guess). Apart from a few hiccups with apcu, I had no problem following episode 1 and 2, but for Doctrine I needed MySQL, so I had to dockerize the whole project. That's how I found your solution. The good news: it works. Bad news: it's painfully slow. A simple page reload takes about 1500-2000 ms (even with cached volumes), and this is a very simple tutorial page. Again I looked around, and one of the probable causes might be the vendor or the cache folder, but since I'm not comfortable with Sf4 yet, I don't want to rearrange anything in the project structure. I use a hefty HP notebook with a recent i7 CPU and 16gigs RAM. What makes it even stranger, never had the same experience with Laravel and Slim projects which we run with a monstrosity called Laradock. What's your dev experience regarding this?

Cheers.

I've been building a dev and testing environment for a 2.8 project for a few months now, on a Windows desktop.
Performance is a huge issue.
I managed to mitigate the problem using an NFS mount on the dev env, and moving cache and log directories out of the shared source directory.
Moving the vendors also noticeably improves performance, but it has a few gotchas, and I've stopped doing it for now.

I might write something about this, because I've been pulling my hair trying to get a working stack on both Windows and Linux, and there are flaws in every single post I've found including this one.

[the-necroposter]

payskin 4/12/2019

Hey Victor, thank you for the heads-up.

The dev environment I use on Win10 is built upon connecting to the Docker for Windows daemon from WLS (Ubuntu 18.04 on the Linux subsystem). Check out this guy's blog: https://nickjanetakis.com/ he has a working solution for this setup (Win10 + Docker for Windows + Ubuntu 18.04 on WSL + native Docker CE and docker-compose on Ubuntu).

In the mean time, I've managed to solve the mysql 8 authentication problem I mentioned above with a simple "command" line in the mysql section of docker-compose.yml that sets the default auth plugin to mysql_native_password. The very next day it turned out that our database was being hosted on Google Cloud SQL that does not support MySQL 8. :D So, I had to dial back to 5.7 which does not have this auth problem. Sigh.

Regarding Symfony's performance in Docker, all the other backend devs around me use Ubuntu on their PCs (I'm the only Windows guy left), and the performance is way better in those environments, but like 4-5x times better. My 2500 ms request goes through in 500 ms or less on their PCs. Same code, same Docker setup, the only difference is in the dev enviroment. I'm looking forward to the new Win10 update in May and will reinstall my notebook and all the WSL stuff with it. We'll see if a fresh start helps or not.

Cheers.

[the-necroposter]

Victor Toulouse 4/12/2019

Oh god… Docker on WSL? Why? I'm having enough trouble with just Docker for Windows 😅
I'll check the blog, though.

Anyway, yes, native bind mounts on Windows (they use, err… Samba, I think?) have catastrophic performance, but NFS with WinNFSd works. That's what some people use with Vagrant VMs on Windows, too.

Hi! How can I add yarn to my projects?

[the-necroposter]

Nicolas NSSM 4/15/2019

You can just add a new Nodejs container to your docker-compose.yml file :
https://hub.docker.com/_/node

Morgan Caron 4/5/2019

Hello ! Thank you very much for this article.
With the given configuration, it seems that the database data will be lost every time the container is restarted or stopped.

How do you manage your db data in production?

[the-necroposter]

Victor Toulouse 4/12/2019

Ha, you're right! I was focusing on nginx and didn't even notice this.
You need a named volume, or a bind mount (less efficient, but safer).
I think this project can be trusted:
https://github.com/Sylius/S...

[the-necroposter]

Victor Toulouse 4/11/2019

On you "production" docker-compose.yml, you did'nt specify any bind mount nor any context or Dockerfile.
How is the public directory shared with nginx, then?

You may copy the public directory to the nginx container, but if you run the symfony scripts in the php container, nginx won't know about compiled assets and symlinked vendor assets.

Also, you first COPY your source code in the php container, then on the second example of your docker-compose.yml, you declare a bind mount.

Egor Ushakov 5/20/2019

Thanks for the article! At which level do you place the root of your Git repository for the environment described in the article?

[the-necroposter]

Lénaïc Couellan 7/17/2019

Hello Egor ! Thank you for your feedback.

In most cases, we put the git repository at the root of the project. At the same level as the env file and docker compose file.

[the-necroposter]

Egor Ushakov 5/20/2019

Why do you set additional level in your tree as /apps? Why not placing my-symfony-app right at the root?

[the-necroposter]

Lénaïc Couellan 7/17/2019

As we said in the article, it is just a structure we use at KNP, you can structure your project the way you want.
This structure allow us to place an other app (like a front app) at the same level as the symfony app.

[the-necroposter]

Egor Ushakov 5/20/2019

I think you do not use volumes for php-fpm image due to performance issues. And instead you just COPY apps/my-symfony-app /usr/src/app at the stage of building php-fpm image. Am I right saying you then use deployment/sync over SFTP to live update Symfony app source files inside the php-fpm container? Thank you!

[the-necroposter]

Lénaïc Couellan 7/17/2019

We use volumes for the deploiement as you can see in the docker-compose.override.yml.

There is this specific lines :


services:
php:
volumes:
- ‘./apps/my-symfony-app/:/usr/src/app’


[the-necroposter]

Egor Ushakov 7/28/2019

It's OK on Linux, but seems to be very (not extremely but sort of) slow on Mac. Even `:cached` volume mounting option does not help. Simple page reload takes up to 2 seconds or more.

[the-necroposter]

Lénaïc Couellan 8/7/2019

There is indeed issues with Docker on MacOs. Docker is not handled correctly. You can maybe add more RAM on your Docker so it will be faster.

[the-necroposter]

Astrophel 1/30/2020

Volumes are slower then copying in, you are correct

[the-necroposter]

Mamy Raoby 6/8/2019

Since Symfony 4.2.8 , it needs zip extension for PHP to be installed, so add the following lines on docker/php/Dockerfile


RUN apt-get update && \
apt-get install -y \
zlib1g-dev
RUN docker-php-ext-install zip


[the-necroposter]

Nour 7/21/2019

Hello,

This is a pretty good stuff here, thank you for sharing. That is very kind of you.

I tried with my Symfony project, sadly it required at least php 7.3. And I could not find anywhere how to change the php version whitout messing up the all thing.

If anyone have the answer that Im looking for.

Regards

[the-necroposter]

Lénaïc Couellan 7/22/2019

Hello, thank you so much for your reply.

You can change the base image of PHP in your docker file located in docker/php/Dockerfile.

You have the name of the available libraries right here :
https://docs.docker.com/samples/library/php/

I personnaly suggest you to use the 7.3-fpm

[the-necroposter]

Nour 7/23/2019

Yes it works perfectly !

Thank you so much.

Hi guys, I'm having an error at Step 9/10 : COPY apps/my-symfony-app /usr/src/app

ERROR: Service 'php' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder794234457/apps/my-symfony-app: no such file or directory

Any idea what's going on? Thanks!

[the-necroposter]

Lénaïc Couellan 7/22/2019

Hello !
Your architecture is not the same as the one used in this article.
You should go back to the second step : organize the project directory.

Your substitution copied your whole project directory, it is better to only copy your symfony app, the container is fit for a php project.

[the-necroposter]

MalcolmXTC 7/22/2019

Could you please be more specific?

Are you saying "COPY apps/my-symfony-app /usr/src/app" should work?

[the-necroposter]

Lénaïc Couellan 7/22/2019

Yes just check you have a directory apps and a subdirectory my-symfony-app in there

[the-necroposter]

Mateus Scheper 9/27/2019

I think the command tries to copy apps/my-symfony-app (in your machine) to /usr/src/app (inside docker). Correct me if I'm wrong

Joe Yeung 7/29/2019

That's great... but how to clear cache???
i m using symfony 3 and run...

docker-compose exec php php /usr/src/app/app/console cache:clear

it just say [RuntimeException] unable to create teh cache directory.......

[the-necroposter]

Joe Yeung 8/1/2019

Thanks guys,

I tried to put my symfony and finally success..
How to access the symfony logs which locate in /usr/src/app/app/logs ?

Cheers.

[the-necroposter]

Lénaïc Couellan 8/7/2019

Hello Joe,

If you have the same architecture, your logs are in :

apps/
- my-symfony-app/
- var
- logs

And in your container :

/usr/src/app/var/logs

Installing php:7.3-fpm

RUN pecl install apcu-5.1.8
and
RUN apt-get update && \
apt-get install -y \
zlib1g-dev

does not work anymore, you can replace these command by :
RUN pecl install apcu
and
RUN apt-get update && \
apt-get install -y \
libzip-dev

Gustavo 11/10/2019

Hey tks, tks for the article it works perfectly.

I am trying to build the nginx image along with the conf and public/ so it is easier for the deployment in prod.

The thing is, no matter how I try it does not work if I copy apps/symfony/public to /usr/src/app/public in dockerfile, it only works if I bind it as a volume. The conf works though..

I always get this error msg *ClassNotFoundException*:
Attempted to load class "MakerBundle" from namespace "Symfony\Bundle\MakerBundle".
Did you forget a "use" statement for another namespace?
in Kernel.php line 23
at Kernel->registerBundles()
in Kernel.php line 429
at Kernel->initializeBundles()
in Kernel.php line 130
at Kernel->boot()
in Kernel.php line 193
at Kernel->handle(object(Request))
in index.php line 25

Here is my dockerfile:

FROM nginx:1.15.3-alpine

COPY apps/symfony/public /usr/src/app/public

COPY docker/nginx/default.conf /etc/nginx/conf.d/default.conf

Any ideas of what I am doing wrong?

[the-necroposter]

Gustavo 11/10/2019

figured it out! :)

I was messing up composer dev with prod...

was using --no-dev --optimize-autoloader in dev mode :P

Alexter 12/1/2019

Hello

I'm starting to use Docker for my Symfony Project, and so try your tutorial. But i have some trouble on the composer install :


Cannot create cache directory /.composer/cache/repo/https---repo.packagist.org/, or directory is not writable. Proceeding without cache
Cannot create cache directory /.composer/cache/repo/https---repo.packagist.org/, or directory is not writable. Proceeding without cache


[RuntimeException]
/usr/src/app/vendor/ocramius/package-versions does not exist and could not be created.


It's look like persmission, but i don't know how to fix this.

Thanks

[the-necroposter]

Alexter 12/15/2019

No idea ? :(

[the-necroposter]

Lénaïc Couellan 12/24/2019

Hello Alex !
Sorry for the late reply.
This error looks like your project was create by a specific user and it is not the same on your docker container.
There is some tests you can do :
- Look at the userId of your computer and check it is 1000. If not, you have to change it in your env file.
- Remove your vendors and `composer install`, you can also use `composer clear-cache". Never use sudo with a composer install.
- If none of this works, try to chown with the username of your device. It can fix the problem but there is an other problem behind.

Hope this helps.

[the-necroposter]

Alexter 12/27/2019

It helps, and not :D
I was on PowerShell, can't find user id (only SID). After many try, i left it and install WSL with Ubuntu 18.04. Works better, now i can make a clear install of SF4 and see something on ly http://localhost

Thanks for help :)

I go to localhost and it says "it works ! "
why ?

[the-necroposter]

Lénaïc Couellan 6/23/2020

Hmm it can be many things.
Maybe an other service is running on your port 80.
Maybe your nginx is not correctly plugged to the symfony app. Check that the nginx configuration is looking for the good index.php or app.php and let me know.

[the-necroposter]

What is the host name or IP of the Datebase in the docker network? Cannot reach it from adminer.

[the-necroposter]

Lénaïc Couellan 6/23/2020

If you want to communicate between your containers, you must use the name of the service defined in your docker-compose.yml.

In this article, it is : mysql.

The default host of mysql is 3306.

If you prefer apache over nginx and you need phpmyadmin, mysql, email dockerized services, I would recommend checking this repository - https://github.com/kastecki...

**Edward ** 8/16/2020

a great article, just what i was looking for!

[the-necroposter]

Galgaldas 9/7/2020

I would also recommend checking out this. All you need to do is download couple of files and you can already write docker-compose up and it will work - https://github.com/kastecki...
