从 Jenkins 批量删除 ec2 快照

  • 772

用例：
将 txt 文件 (old_snapshots.txt) 中的快照列表导出到 S3 存储桶。从 Jenkins，使用 aws cp 命令将文件复制到 Jenkins /tmp/directory

--dry-run did not show any error

但是，当在 Jenkins 中使用 aws delete 命令传递以下 bash 行时，它显示 SUCCESS，同时表示发生了错误并且未删除快照。

## 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"

输出

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

Finished: SUCCESS

请求：这个错误An error occurred (InvalidParameterValue) when calling the DeleteSnapshot operation似乎太笼统了？有没有人遇到过似乎问题？此外，我通过在 Jenkins 中手动添加快照 id 进行了手动测试，使用 aws cli 仅删除单个快照，并且效果很好。任何建议将不胜感激。

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

  1. 你需要稍微改变你的脚本。

    $ 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

    您的脚本调用file变量是常量，但您需要逐行传递文件的内容。所以，在下面替换

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

    和

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

    为了其他社区用户的利益，我使用该--debug标志发现附加字符'\r'被添加到snap-#

    调试输出

    解决问题：我传递tr -d '\r'给持有该值的变量，以进行对话。

    示例：

    tr -d '\r' < input > output

    更新的脚本 

    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
