[PowerShell] 笔记- 搭配PowerShell完成自动化部属

延续先前使用gitlab的CI流程，这次加入PowerShell完成后续CD的流程，笔记一下这次的内容
神父
这次为yml档加上deploy的stage，很单纯的只呼叫ps1做事，
专案有两个ps1，皆放在资料夹Ps1中

1. stages:
   
2.   - deploy
   
3. 
   
4. before_script:
   
5.   - chcp 65001
   
6. 
   
7. deploy:
   
8.   stage: deploy
   
9.   script:
   
10.       - dotnet publish ./MyProject/ -c release -o ./output
    
11.       - ./Ps1/PreDeploy.ps1 $env:DeployAccount_Stage $env:DeployPassword_Stage

dotnet发布./MyProject/ -c版本-o ./output
指定release组态发布，并且指定发布的位置在“./output”

$ env：DeployAccount_Stage
PowerShell取得环境变数的方式，相关值会存在gitlab的“Settings > Variables”

./Ps1/PreDeploy.ps1 $ env：DeployAccount_Stage $ env：DeployPassword_Stage
执行PreDeploy.ps1，并且传入两个值

PreDeploy.ps1（GitLab Runner）
