Docker

At GRRR, we use Docker for local development and more. This ensures development-production parity, and prevents a lot of manual configuration work.

Anatomy of a Docker command:

docker-compose -f docker-compose.testing.yml exec php php artisan clear:cache

docker-compose You can run commands using docker, or using docker-compose. Usually you will use docker-compose, since that is what we use.
-f docker-compose.testing.yml This is a flag passed to the docker-compose command. In this case we instruct it to use config file docker-compose.testing.yml. Usually optional, until you need something advanced.
exec php This executes a command on a running container named php. An alternative to exec is run, which is used to run a command on a container that is not running, such as yarn build on our conventional builder container. php is not a command, but the name of the container.
php artisan clear:cache This is the command that you execute on the container. It's a PHP command, executed in this case on a container that is also named php.
