[AWS]使用AWS CLI 清除 CloudFront 快取
@ GordonWei · Saturday, Nov 30, 2019 · 1 minute read · Update at Nov 30, 2019

剛好有遇到這個問題紀錄一下。

在aws官方說明中,其實清除快取這個動作稱之為create invalidation(使物件失效)

在執行前,請先確定有安裝aws cli以及有權限執行create invalidation

首先,必須要先找出要清除快取的CloudFront ID,如下方指令:

aws cloudfront list-distributions | grep Id

應該會回傳如下方的回應:

    "Id": "ABCDEFGHIJK012",
        "Id": "Blah Blah Blah",
        "TargetOriginId": "Blah Blah Blah",
        "FieldLevelEncryptionId": ""
    "WebACLId": "",
    "Id": "1234567890ABCD",
        "Id": "Blah-Blah-Blah",
        "TargetOriginId": "Blah-Blah-Blah",
        "FieldLevelEncryptionId": ""
    "WebACLId": "",

假設我們要刪除的是ID:1234567890ABCD,那麼我們要下:

aws cloudfront create-invalidation --distribution-id 1234567890ABCD --paths /*

就會回傳如下方一大串的回應:
