Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

	FROM composer:latest as build
	WORKDIR /build
	COPY . /build
	RUN cp .env.example .env && \
	composer install --ignore-platform-reqs --no-interaction --no-dev --prefer-dist --optimize-autoloader

	FROM alpine:3.12
	LABEL Maintainer="Reishou <[email protected]>" \
	Description="Lightweight container with Nginx & PHP-FPM 7 based on Alpine Linux."
