However when i try to run:

I get the following error:

Can you please tell me what is the problem here?

I'm quite bad at creating docker-compose and I currently have a problem when I try to build a new project.
After the build I can't access my mariadb server within my php app container, I've got this error:
PDO::__construct(): php_network_getaddresses: getaddrinfo for mariadb
failed: Name does not resolve
So I know something is misconfigured but I don't know what, yet. I tried many changes but nothing that worked.
Here is my current docker-compose.yml:
version: "3.8"

Can someone help me to fix the issue please?
Thanks !
The problem wasn't related to my docker-compose configuration file.
My app is a PHP Symfony app and it was doing a "cache:clear" after the initial "composer install" during the build. The "cache:clear" was triggering calls to the database which wasn't ready yet.
To solve this I just had to set my mariadb version to my "DATABASE_URL" parameter in my Symfony app, to avoid useless database queries.
I get the following errors when I try to access phpmyadmin.

getaddrinfo failed: Temporary failure in name resolution

I have a WP project with following docker-compose configuration. When I try to connect my http://localhost to access the installation, I get 500 and I read this in the log:
PHP Fatal error: Uncaught mysqli_sql_exception: Connection refused in /var/www/html/web/wp/wp-includes/wp-db.php
I assume there is something wrong with the ip or the host but the weird thing is that phpmyadmin is working fine, and it connects with mysql without issues.

My wordpress .env, among the other settings, set the host like the following:
DB_HOST="mysql:3307"
But I also tried
DB_HOST="mysql:3306"
or simply
DB_HOST="mysql"
Do you have any suggestions?
Thanks.
your Wordpress Instance and MySQL Instance isn't connected. Try adding networks on the docker-compose.yml
nginx:
...
networks:
- your-network-name
mysql:
...
networks:
- your-network-name
wordpress:
...
networks:
- your-network-name
and on the bottom of the file add:
networks:
your-network-name:
driver: bridge
this is the way to configure docker to be connected each other
I was trying to create a database in my app using command:
php bin/console doctrine:database:create
After that I got an error:
An exception occurred in driver: SQLSTATE[08006] [7] could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?

I'm not using any postgres config file, according to Symfony documentation, there's a config line in .env:
DATABASE_URL="postgresql://root:root#127.0.0.1:5432/symfony_db?serverVersion=11&charset=utf8"
I run netstat command and I got:
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN
I think there's a problem with binding my localhost address where my app's server is running to postgres. Does anyone know, how I can fix it?
In docker-compose all services can be reached by their names.
You need to change DB host address to database - as a service name in docker-compose
DATABASE_URL="postgresql://root:root#database:5432/symfony_db?serverVersion=11&charset=utf8"

The application starts, connects to the database via
DATABASE_URL=mysql://user:123#db:3306/db
But when performing migrations through the console, I get the error
An exception occurred in driver: SQLSTATE[HY000] [2002] php_network_getaddr
esses: getaddrinfo failed: nodename nor servname provided, or not known
As I understand it, due to the fact that the address is specified in the connection db.
How to make migrations?
You need to run console commands from inside of your php container
docker-compose exec php bin/console doctrine:migrations:migrate
You should connect to the container name.
These can be found by running docker container ls on your console.
It's easier when you specify the name in your compose file like so:
services:
db:
container_name: db # This can be anything
image: mysql:8.0.20
