Dockerfile does not create files and folders in Laravel - laravel

Question

I have a Laravel Project and I created a docker-compose and dockerfile.
I do docker-compose build and my problem is that:
It does not create the folder vendor (composer install).
Do not copy .env.local to .env
Do not create the node_modules folder
docker-compose.yml
version: "3"
services:
api:
container_name: nadal_api
build:
context: .
dockerfile: Dockerfile
volumes:
- .:/var/www/html/app
ports:
- 5002:80

Can it be the permissions?

Answer 1

When building the image, you COPY your whole current directory to /var/www/html/app, then stuff happens with the content there. On docker-compose up, you mount your whole folder again at this destination, which overwrites everything that happened on docker-compose build. To avoid this, just remove the volumes part from your docker-compose.yml.
