## Docker Usage for Local Development

This documents hwo to use docker for local development on OSX but can be modified to run under
windows, it uses a multi stage build process and the latest alpine images to keep the container sizes to a minimum.
it fully supports xdebug and a server version of mysql server. This presents a very fast development
experience that does not pollute the host operating system.

### Why I Use Docker

Docker plays a crucial role in my deployment strategy. It allows me to containerize my Laravel applications, ensuring
consistency across different environments and across multiple services that I need to run a production Laravel app -
Queue workers, Schedulers, Nightwatch agent, etc..

1. Consistent Environments: Every deployment maintains the same configurations, reducing bugs and deployment issues.

2. Scalability: Docker’s lightweight containers.

3. The possibility for automated deployment, Integration with Git allows for continuous deployment workflows.

## Docker Compose

1. We assume you have docker installed and running
2. and also docker-compose installed
3. you can also use laravel sail *** the configuration overrides the default sail definitions

You need to create a docker directory from the project root
and add the following files to this directory once downloaded.

[Download docker.zip](assets/docker.zip){: download}

you will also need to contact the author for a copy of the mysql databases;

Once all the files are in place you can execute

```
 sail up --build
 or 
 docker-compose build --no-cache
```

Fix invalid cache path after rebuild as were using names paths

You can also use this command

````
docker exec -it laravel-php bash -lc \
"mkdir -p bootstrap/cache storage/framework/{cache,sessions,views} \
&& chown -R www-data:www-data bootstrap storage \
&& chmod -R ug+rwX bootstrap storage"
`````

NB also run composer install

````
docker network create shared-frontend
````

This makes the necessary cache dirs etc

````
mkdir -p bootstrap/cache storage/framework/{cache,sessions,views,testing,cache/data} && chown -R www-data:www-data bootstrap storage
````
