Running via Docker Compose

Follow these steps to test this on your local machine.

1. Configure .env

Copy over .env.example → .env

cp .env.example .env

2. Bring up containers

./vendor/bin/spin up

3. Run migrations

./vendor/bin/spin exec php php artisan migrate

👉 EXPECTED RESULT: Migrations should Run

You should see something like:

2014_10_12_000000_create_users_table ......................................................... 8ms DONE
2014_10_12_100000_create_password_resets_table ............................................... 8ms DONE
2019_08_19_000000_create_failed_jobs_table .................................................. 10ms DONE

Running as a compiled docker image (with "docker run")

To test a compiled image.

1. Configure .env

Copy over .env.example → .env

2. Build docker image

docker build -t localhost/laravel-env-test-php .

3. Create a docker network

docker network create laravel-env-test-network

4. Bring up a test MariaDB container

docker run --rm \
	--name=mariadb \
	--network=laravel-env-test-network \
	-e MYSQL_ROOT_PASSWORD="rootpassword" \
	-e MARIADB_DATABASE="laravel" \
	-e MARIADB_USER="example-app-user" \
	-e MARIADB_PASSWORD="example-app-password" \
	mariadb:10.7

3. Run the docker image (with environment variables)

docker run --rm \
	--name=laravel-env-test-php \
	--network=laravel-env-test-network \
	-p 80:80 \
	-p 443:443 \
	-e DB_CONNECTION=mysql \
	-e DB_HOST=mariadb \
	-e DB_PORT=3306 \
	-e DB_DATABASE=laravel \
	-e DB_USERNAME=example-app-user \
	-e DB_PASSWORD=example-app-password \
	-e AUTORUN_LARAVEL_MIGRATION=true \
	localhost/laravel-env-test-php

4. Run the migrations

docker exec laravel-env-test-php php artisan migrate

👉 EXPECTED RESULT: Migrations should Run

You should see something like:

2014_10_12_000000_create_users_table ......................................................... 8ms DONE
2014_10_12_100000_create_password_resets_table ............................................... 8ms DONE
2019_08_19_000000_create_failed_jobs_table .................................................. 10ms DONE
