MI SHAJIB'S LARAVEL DOCKER BOILERPLATE

Technologies Used

• Docker: DevOPS Technology used for setting up virtual environments for running containerized applications
• MySQL: Database technology
• Nginx: Web-server application
• PHP Laravel: Server-side Web Framework
• PHPMYADMIN: Database Administration
• Bootstrap: Front-end CSS styling framework

Docker for developer environment

Install Docker

Visit https://docs.docker.com/get-docker for instructions.

Install Docker Compose (linux only)

Visit https://docs.docker.com/compose/install for instructions.

Switch to Linux containers (windows only)

Right-click on the Docker icon in Taskbar and choose "Switch to Linux containers..."

Prepare repositories

Clone this repository first. And then follow next step.

Prepare app folder

App requires permissions to write into storage and bootstrap/cache folders.

Linux/macOS:

sudo chmod -R ag+w <path-to-backend-folder>/bootstrap/cache
sudo chmod -R ag+w <path-to-backend-folder>/storage

Windows:
Use File Explorer to change permissions for these folders.

Configure docker-compose

In app folder, copy .env.example to .env and edit it accordingly:

• COMPOSE_CONVERT_WINDOWS_PATHS=1
  Uncomment this line on Windows OS. That will tell Docker to interconvert unix/win paths.
• LISTEN_IP
  IP address to listen incoming HTTP connections. If you already have nginx listening on 127.0.0.1:80 port then you can bind docker containers to listen on another IP (default 127.0.0.2).
  Warning: If already have nginx working on your host, make sure they are not bound to 0.0.0.0, that will prevent nginx container from starting. Rebind your host nginx to 127.0.0.1 instead.
  macOS users: By default macOS doesn't bind other 127.0.0.* to loop back adapter, so you have to do that yourself:
  sudo ifconfig lo0 alias 127.0.0.2 up

macOS / Windows only: You have to allow docker engine to bind mount your app folder into containers:

1. Open Docker Agent preferences
2. Select Resources → File Sharing in the left menu.
3. Add the folder you cloned.

Configure hosts

Docker containers configured to work on laravel-docker.local.
You have to add these records to your /etc/hosts (linux/macos) or %WIN_DIR%\System32\drivers\etc\hosts (win).

127.0.0.2 laravel-docker.local

You'll need root/administrator privileges to edit this file.

Build and run containers

Open terminal/console and run:

docker-compose build

Building could take some time, because Docker will pull all needed images from Docker Hub.

When it's done you're ready to run containers:

docker-compose up -d

First run could take some time, because application will install needed dependencies. WAIT for sometimes (like - 5 to 10 minutes) after executing docker-compose up -d for the first time.

To start/stop containers you can use docker-compose stop and docker-compose start.
To remove containers you can use docker-compose down.
To show containers status you can use docker-compose ps, it should show something like that:

   Name                  Command               State                  Ports               
------------------------------------------------------------------------------------------
lr-docker-backend           /entrypoint.sh php-fpm           Up      9000/tcp                           
lr-docker-mysql             docker-entrypoint.sh mysqld      Up      127.0.0.2:3337->3306/tcp, 3306/tcp
lr-docker-nginx             /docker-entrypoint.sh ngin ...   Up      127.0.0.1:32782->80/tcp            
lr-docker-phpmyadmin        /docker-entrypoint.sh ngin ...   Up      127.0.0.1:32782->80/tcp            

Containers description

There are 4 containers:

• lr-docker-nginx
  Listens incoming web requests (HTTP) and dispatches them to app.

• lr-docker-mysql
  MySQL database for app. On first run it will be seeded with admin user account and dev hotel id/context.
  Login/password: admin@laravel-docker.local/123123123.
  You can access this DB from your host using 127.0.0.2:3337.
  Database content preserved between container restarts, but cleaned up upon down command.

• lr-docker-phpmyadmin
  PhpMyAdmin. We can manage database by this. You can access this by - 127.0.0.2:8200.

• lr-docker-backend
  Backend. Server using php-fpm (7.4). Exposes port 9000.

You can restart container using docker-compose restart <container-name>, for example: docker-compose restart lr-docker-backend.
If you'll omit container name, then all containers will be restarted.

Happy coding, do something wonderful ;)
