從 Jenkins 批次刪除 ec2 快照

從 Jenkins 批次刪除 ec2 快照

使用案例：
將 txt 檔案 (old_snapshots.txt) 中的快照清單匯出到 S3 儲存桶。從 Jenkins，使用 aws cp 指令將檔案複製到 Jenkins /tmp/directory

--dry-run did not show any error

但是，當在 Jenkins 中使用 aws delete 命令傳遞以下 bash 行時，它顯示成功，同時表示發生了錯誤且快照未刪除。

## actual deletion
        file="/tmp/old_snapshots.txt"
         while read delete_data
         do
        aws ec2 --region eu-west-1 delete-snapshot --snapshot-id $file
        echo "Deleting snapshot $delete_data"
        done <"$file"

輸出

An error occurred (InvalidParameterValue) when calling the DeleteSnapshot operation: Value (/tmp/old_snapshots.txt) for parameter snapshotId is invalid. Expected: 'snap-...'.
Deleting snapshot snap-xxxx81xxxxxx7fxxx

An error occurred (InvalidParameterValue) when calling the DeleteSnapshot operation: Value (/tmp/old_snapshots.txt) for parameter snapshotId is invalid. Expected: 'snap-...'.
Deleting snapshot snap-xxxacc49xxxxxxc26

要求：這個錯誤An error occurred (InvalidParameterValue) when calling the DeleteSnapshot operation似乎太籠統了？有人遇到過似乎問題嗎？此外，我還進行了手動測試，透過在 Jenkins 中手動新增快照 ID，使用 aws cli 刪除單一快照，效果很好。任何建議將不勝感激。

包括aws命令

aws ec2 --region eu-west-1 delete-snapshot --snapshot-id snap-01x1618xxxxxxa51x
Found snapshotid: snap-01x1618xxxxxxa51x in the uploaded file: /tmp/old_snapshots.txt
Now deleting snapshot id snap-01x1618xxxxxxa51x

您需要稍微更改一下腳本。

$ sh abc.sh

What is in delete_data snap-xxxx81xxxxxx7fxxx
What is in file /tmp/old_snapshots.txt
Deleting snapshot snap-xxxx81xxxxxx7fxxx
What is in delete_data snap-xxxacc49xxxxxxc26
What is in file /tmp/old_snapshots.txt
Deleting snapshot snap-xxxacc49xxxxxxc26
What is in delete_data snap-04xxxxxxxx3fa3cxxxxxxf4
What is in file /tmp/old_snapshots.txt
Deleting snapshot snap-04xxxxxxxx3fa3cxxxxxxf4

$ cat abc.sh
## actual deletion

    file="/tmp/old_snapshots.txt"
    while read delete_data
    do
    #aws ec2 --region eu-west-1 delete-snapshot --snapshot-id $file
    echo "What is in delete_data $delete_data"
    echo "What is in file $file"
    echo "Deleting snapshot $delete_data"
    done < $file

您的腳本呼叫file變數是常數，但您需要逐行傳遞檔案內容。所以，替換下面

aws ec2 --region eu-west-1 delete-snapshot --snapshot-id $file

和

aws ec2 --region eu-west-1 delete-snapshot --snapshot-id $delete_data

為了其他社區用戶的利益，我使用該--debug標誌發現附加字元'\r'被添加到折斷-＃

偵錯輸出

為了解決這個問題：我傳遞tr -d '\r'給保存該值的變數來進行對話。

例子：

tr -d '\r' < input > output

更新腳本

file="/tmp/old_snapshots.txt"
cat $file | tr -d '\r' | while read -r line; 
do 
aws ec2 --region eu-west-1 delete-snapshot --snapshot-id $line                        
done
