前情提要

各位邦友，既然程式經過「套件安裝」「測試」「打包」之後，再來就是要進行「佈署」的事情(Travis CI 佈署支援)。只要涉及服務跟服務之間要溝通運作。就要經過「授權」「設定」的過程。由於Travis CI 要透過.travis.yml來跟「佈署提供者」互動。部份「設定」，要使用Travis CI Client來完成。

安裝Travis CI Client

小編電腦是Windows

• 安裝ruby：RubyInstaller
• 打開Git Bash輸入指令：ruby -v，確認安裝結果。

    $ ruby -v
    ruby 2.5.3p105 (2018-10-18 revision 65156) [x64-mingw32]
  

• 用ruby的套件管理gem安裝Travis CI Client
  確認安裝結果：travis version

    $ gem install travis -v 1.8.9 --no-rdoc --no-ri
    $ travis version
      1.8.9
  

用Travis CLI完成.travis.yml deploy s3設定

• 登入：travis login --pro

    $ travis login --pro
    We need your GitHub login to identify you.
    This information will not be sent to Travis CI, only to api.github.com.
    The password will not be displayed.
  
    Try running with --github-token or --auto if you don't want to enter your password anyway.

• 指令協助設定deploy(s3)：travis setup s3

    $ travis setup s3
    Access key ID: AKIAIA2J7HXUI52NHMHA
    Secret access key: ****************************************
    Bucket: bright-travis-deploy
    Local project directory to upload (Optional): dist
    S3 upload directory (Optional):
    S3 ACL Settings (private, public_read, public_read_write,authenticated_read,
       bucket_owner_read, bucket_owner_full_control): private
    Encrypt secret access key? |yes|
    Push only from bebright/slack-demo? |yes|
  

  .travis.yml(新增設定)

    deploy:
      provider: s3
      access_key_id: AKIAIA2J7HXUI52NHMHA
      secret_access_key:
        secure: JPDcEKISOrS4YK31WC...太長了(省略)
      bucket: bright-travis-deploy
      local-dir: dist
      acl: private
      on:
        repo: bebright/slack-demo
  

• .travis.yml(新增設定)
  skip_cleanup: true：這一行真的很雷，不加的話，travis會把你build出來的東西清掉，搞超久的@@。

    deploy:
      # 同上
      skip_cleanup: true
  

AWS S3 設定

• 建立S3 bucket：bright-travis-deploy，建立步驟可參考這篇
  
• 設定S3權限to IAM User：travis ci policy，建立步驟可參考這篇
  travis ci policy(JSON)

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "s3:DeleteObject",
                    "s3:DeleteObjectVersion",
                    "s3:GetBucketAcl",
                    "s3:GetObject",
                    "s3:GetObjectAcl",
                    "s3:GetObjectVersion",
                    "s3:GetObjectVersionAcl",
                    "s3:ListBucket",
                    "s3:PutObject",
                    "s3:PutObjectAcl",
                    "s3:PutObjectTagging"
                ],
                "Resource": [
                    "arn:aws:s3:::bright-travis-deploy/*"
                ]
            }
        ]
    }
  

travis執行結果(略)，直接看S3 Bucket

哇…今天「試」超~~~~~~久的…差點就在倒數第二天陣亡了。Orz
