Check if you have the vendor directory in the project directory inside the container to see if your correctly mapped your volumes.

Laravel in Docker: Class "PDO" not found
Hello developers,
I try to run Laravel with Docker but when I run php artisan migrate I get the error Class "PDO" not found.
This is docker-compose file that I use:
version: 3.4
services:
php-apache-environment:
container_name: php-apache
build:
context: .
dockerfile: Dockerfile
depends_on:
- db
volumes:
- ./www:/var/www/html:Z
ports:
- 8000:80
db:
container_name: db
image: mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: zqw36vuahnrk
MYSQL_DATABASE: laravel-mvc
MYSQL_USER: laravel-user
MYSQL_PASSWORD: dw3kngbtd773
ports:
- 9906:3306
volumes:
- dbdata:/var/lib/mysql
phpmyadmin:
image: phpmyadmin/phpmyadmin
ports:
- 8080:80
restart: always
environment:
PMA_HOST: db
depends_on:
- db
With this Dockerfile
FROM php:8.1-apache
RUN docker-php-ext-install pdo pdo_mysql
RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
RUN apt-get update && apt-get upgrade -y
I run the command php artisan migrate on the host.
When I run php artisan migrate inside the container I get the error Illuminate\Database\QueryException SQLSTATE[HY000] [2002] No such file or directory.
Do somebody have an idea what I could do wrong / what I can do?

Thanks for thinking along! I check the directory vendor from inside the container and I can view all the files and directories properly.
This is the database section in .env:
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=laravel_mvc
DB_USERNAME=laravel-user
DB_PASSWORD=dw3kngbtd773
I'm clueless at the moment.

@ScottTrakker That database name is different from the one on the file laravel-mvc

Oh damn, you are right!
Sadly, after changing the name and restarting everything, the error Class "PDO" not found persists :-(.

@ScottTrakker In your container, what's the result of php -m?

The result of php -m in the container php-apache is:

I was thinking: the reason why it doesn't work outside of the container, is that PDO is not installed on the host (and I also don't want to). The good way to run php artisan migrate is properly only from inside the container. But when I do that I get the error below.
Illuminate\Database\QueryException
SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from information_schema.tables where table_schema = laravel-mvc and table_name = migrations and table_type = 'BASE TABLE')
Maybe this error message is more important than the class not found error?
Thanks for helping me so far!

I solved it!!!
I changed DB_HOST=localhost to DB_HOST=db and then ran php artisan migrate from inside the container and it worked!!!
Thanks for being with me :-) !
