I have read and follow the instruction of the gitlab website. Maybe my mistake is obvious, but I can't see it.
As you are using MySQL that is running in another container, you have to use its hostname, not 127.0.0.1. The correct database host should be "mysql". This is covered in one of the sections of the GitLab's documentation:
The service container for MySQL will be accessible under the hostname mysql. So, in order to access your database service you have to connect to the host named mysql instead of a socket or localhost.
One of the possible reasons for this error is that you attempt to access the database while it still initialises. This is covered in the MySQL's caveats section on the Docker HUB.
If there is no database initialised when the container starts, then a default database will be created. While this is the expected behaviour, this means that it will not accept incoming connections until such initialisation completes. This may cause issues when using automation tools...
A crude solution would be to use sleep command before you start any process that accesses database. You can add it to the before_script section:
before_script:
- sleep 60s
A better and more complex solution would be to probe the MySQL server, repeatedly checking whether it already accepts connections.

I started a new Laravel 9.x + JsonApi project on docker-compose with 2 containters, 'web' and 'mysql'. Artisan migrations, seeding and db:show works fine. But when I'm trying to load a page from browser or Postman, it returns DB error
`SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for mariadb failed: Temporary failure in name resolution
select * from redirects where redirects.id = 1 limit 1 `
The weird part is that my DB host is mysql and 'mariadb' string is never mentioned in my code (except some vendor files), nor in docker files, nor in .env file. I also checked container environment variables - nothing there.
Artisan scripts work fine.
Here are my settings, if it helps. Mariadb was never mentioned, it was mysql from the very beginning.

I'm out of ideas what to try and where it takes this mariadb host at all.
I could solve the problem by defining the DATABASE_URL=mysql://root:PASSWORD#mysql/url_shortener in my .env file. I still have no idea where it got mariaDB host from.

I have PHP and Postgresql installed on OpenBSD 7.0 (VPS). PHP is working (I can echo from an index.php file). And my Postgresql server is running (I can connect and create tables from the command line) but I can't get PHP to connect.
I suspect it has something to do with PHP not being able to access the DB socket (because it operates in chroot). Or it's related to my postgresql.conf not using "localhost" (explained below). But I'm not lost on trying to solve for those.
/etc/httpd.conf
(port 80 blocks are also there and redirect to 443)
server "db.example.com" {
listen on * tls port 443
root "/htdocs/db"
directory index index.php
authenticate with ".htpasswd"
tls {
certificate "/etc/ssl/db.example.com.fullchain.pem"
key "/etc/ssl/private/db.example.com.key"
}
location "*.php" {
fastcgi socket "/run/php-fpm.sock"
}
}
(and /etc/acme-client.conf is aligned and certificate installed)

Did you activate the PG PHP module by copying or symlinking its .ini file to /etc/php-8.0/? If not, take a look at the "Extension modules" section of /usr/local/share/doc/pkg-readmes/php-8.0:
For all extensions packaged separately (and for opcache), you will
find a file named /etc/php-8.0.sample/(MODULE_NAME).ini. To enable it,
add a symlink into /etc/php-8.0 and restart:
ln -sf ../php-8.0.sample/MODULE_NAME.ini /etc/php-8.0/
To disable, remove the symlink from /etc/php-8.0 and restart:
rm /etc/php-8.0/MODULE_NAME.ini
If you have installed a number of extensions and wish to enable them
all, you can use these shell commands:
# cd /etc/php-8.0.sample
# for i in *; do ln -sf ../php-8.0.sample/$i ../php-8.0/; done
After enabling or disabling extensions (or otherwise modifying php's
configuration), use rcctl(8) to restart php80_fpm or Apache.
I was trying out Docker for the first time. Got a LEMP stack up and running, but I can't connect to the MYSQL Database. Not on my Symfony application, not on PHPMyAdmin. The applications are returning the following error code:

Could someone help me out? Thank you for your time.
The '[2002] Connection refused' means you can reach the database server, but you don't have right access for the user (in your case admin). By default mariadb have a root user with the password given by MYSQL_ROOT_PASSWORD and this user can connect from any server (%).
If you want use an over login to your databases, you have to create it in the databases server with the right granting on databases from chosen locations.
The problem here is that you have named your database server as 'mysql' (service name in the docker-compose file). But by default phpmyadmin tries to connect to a database server named 'db'. Adding PMA_HOST: mysql under the environment section of the phpmyadmin service will resolve this problem.
I think that MYSQL_USERNAME and PMA_ARBITRARY are useless if you work with default configuration (connection with root to your databases server)
I had this challenge because I am running 3 different containers with different IP Addresses
db - 172.18.0.3 - container for MYSQL
app - 172.18.0.2 - container for Laravel app
so I fixed it by editing my Laravel .env file
DB_CONNECTION=mysql
DB_HOST=172.18.0.3
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=username
...
To get your containers Ip addresses. From your docker host
docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
UPDATED:
For latest docker versions and based on the services name, "mysql", in your docker-compose.yml
mysql:
image: mariadb
ports:
- 3306:3306
You can try this:
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=username
DB_HOST is the name of MySQL service name defined in docker-compose.yml
I've managed to connect to the mysql instance using mysql command line tool, this is the command I used - mysql -u root -p -h 127.0.0.1, and the entering the admin password. Is that a sufficient solution for you?
In my case I was running mysql in a docker container whose port was mapped to the host mac (3306:3306). I tried connecting to this database from a phpmyadmin docker container using 127.0.0.1 . But it won't work because the localhost on the phpmyadmin docker container does not have the required mysql running.
To connect to the host from docker network
docker.for.mac.host.internal
Docker Networking Docker Compose Networking
For my instance, the issue was with port mapping somehow.
In my case it was 3307:3306, as soon as I changed it to 3307 on the right side as well, I could connect to the DB instance.
Adding DB_READ_HOST=db solved this problem for me
If you want to know why your connexion failed, you can use in your terminal php artisan tinker and then
like
DB::connection()->getPdo();
Unfortunately this will only give you a part of the error.
Quit tinker and then use this command php artisan db will give you more information like database type, host, port, ad user about the issue.
Like this one

This will not give you the answer on what is wrong, but at least you can understand why your config is wrong.
you need to link the phpfpm container to mysql.
I've just inherited a Symfony2 project from a former co-worker. I'm trying to get it running locally, but am getting a SQLSTATE[HY000] [2002] Connection refused error. I guess I'm missing the database connection that I've read should be in the app/config/parameters.yml file.
Is there anyway of finding this information if all I have is the project and the live site?
If it's standard Symfony2 project you have to configure your database connection information in app/config/parameters.yml, like:
# app/config/parameters.yml
parameters:
database_driver: pdo_mysql
database_host: localhost
database_name: test_project
database_user: root
database_password: password
# ...
More in doc.
After that you have to create database:
$ php app/console doctrine:database:create
Next, create table schema:
$ php app/console doctrine:schema:update --force
Also, you could load (if your co-worker provided it ; ) some data fixtures, so try:
$ php app/console doctrine:fixtures:load
If your coworker doesn't use doctrine fixtures you should consider dumping data from your prod database.
