# PHP :heart: K8s

## 準備環境

### Docker

[Docker 下載](https://desktop.docker.com/win/main/amd64/Docker%20Desktop%20Installer.exe)
[官網教學](https://docs.docker.com/desktop/install/windows-install/)

### Docker compose

桌面版安裝預設應有 docker compose。[官網文件](https://docs.docker.com/compose/install/)
從命令提示字元執行下方指令，出現版本號代表完成

docker compose version

Docker compose 用來在本機環境快速建立整個容器系統

## PHP 程式調整

有一些會有因為佈署對應的參數要設，開放出能透過環境變數設定的能力。
下方例子設定 使用環境變數的`ALL_CONTROLLER_1`的值，不存在的話為後方預設值。
方便從k8s佈署腳本指定不同環境要用的值

define('WebSocketSendCtrlArray',array(
    1	=> getenv('ALL_CONTROLLER_1') ?: 'ws://ruby-csserver.local:9000',
);

## 範例

以一份設定檔描述一個由
* nginx for business
* nginx for client
* mysql
* redis
* php apps
* 各種 game client

組成的環境，啟動的先後順序可由`depends_on`調整。例如nginx啟動前一定要所有的game client端啟動好，nginx需要確認upstream活著才會放心交還給主人。

這份環境有些服務是需含有自己的程式，要經過建置。
描述檔裡面也有指定建置相關的檔案 `build:` 底下
