Laravel Docker-Compose

Question

I've created a repo for some Docker containers that work together with docker-compose to make a very easy and quick installation for Laravel including nginx, mariadb, and redis. Laravel is known for having one somewhat annoying step to get it started, which is that the storage and bootstrap/cache directories have to be writable by the webserver/php process:

chmod -R 777 storage bootstrap/cache

However, docker containers that use shared volumes between the container and host tend to have permission issues because of discrepancies between uids and guids differing between the container and the host.

This is a Mac-only project until I get these basic issues solved.

I would greatly appreciate solutions for how to have the php process user in the php container have write permissions on those directories in the shared volume.

This install script (called by typing ./install into the terminal) is what should be theoretically setting the permissions:

install

#!/bin/bash
echo "installing and building docker containers..."
docker-compose up -d

echo "installing laravel/installer via composer..."
rm -rf code
if [[ $(composer global show) != *laravel/installer* ]]
  then
    composer global require "laravel/installer"
fi

echo "installing laravel..."
laravel new code

echo "changing working directory to code..."
cd code

echo "setting permissions..."
chmod -R 777 storage bootstrap/cache
docker exec ${PWD##*/}_php_1 chgrp -R www-data /code
docker exec ${PWD##*/}_php_1 chmod -R 777 storage bootstrap/cache

echo "installing predis..."
composer require "predis/predis"

echo "installing correct database settings to laravel..."
sed -i '' "s/DB_HOST=127.0.0.1/DB_HOST=mariadb/" .env
sed -i '' "s/DB_DATABASE=homestead/DB_DATABASE=laravel/" .env
sed -i '' "s/DB_USERNAME=homestead/DB_USERNAME=laravel/" .env
sed -i '' "s/REDIS_HOST=127.0.0.1/REDIS_HOST=redis/" .env
sed -i '' "s/CACHE_DRIVER=file/CACHE_DRIVER=redis/" .env
sed -i '' "s/SESSION_DRIVER=file/SESSION_DRIVER=redis/" .env

echo "returning working directory to previous state..."
cd ..

echo "installation complete"
