AWS EBS 卷 - Python - 查找 AWS EC2 EBS 卷控制台中显示的所有字段信息

AWS EBS Volume - Python - Find all fields info as shown in AWS EC2 EBS Volume Console

我正在尝试创建一个 Python 脚本来针对所有可用的 AWS EBS 卷生成一个 csv 格式文件,并显示我在 AWS EC2 EBS 卷中看到的所有字段值控制台。

[arun@Andrews-MBP-2 ~/aks/always-latest-ws-sunny/anisble] $ cat ~/aws-vol-info.py 
import boto3

#define the connection
ec2 = boto3.resource('ec2', region_name="us-west-2")

volumes = ec2.volumes.all()

for vol in volumes:
    print "Created(" + str(vol.create_time) + "),VolumeState(" + str(vol.state) + "),VolumeID(" + str(vol.id) + "),VolumeSize(" + str(vol.size) + ") " + vol.type
[arun@Andrews-MBP-2 ~/aks/always-latest-ws-sunny/anisble] $ 

此脚本给我以下错误消息。原因:如果我不使用 vol.type 字段,上面的脚本就可以工作。它没有工作,因为 volumes 变量在 运行 ec2.volumes.all().

时从未将其转化为它的值
[arun@Andrews-MBP-2 ~/aks/always-latest-ws-sunny/anisble] $ python ~/aws-vol-info.py 
Traceback (most recent call last):
  File "/Users/arun/aws-vol-info.py", line 9, in <module>
    print "Created(" + str(vol.create_time) + "),VolumeState(" + str(vol.state) + "),VolumeID(" + str(vol.id) + "),VolumeSize(" + str(vol.size) + ") " + vol.type
AttributeError: 'ec2.Volume' object has no attribute 'type'
[arun@Andrews-MBP-2 ~/aks/always-latest-ws-sunny/anisble] $ 

我应该在上面的脚本中使用/更改什么 library/function 我可以使用它来显示 EBS 卷的所有字段或一些更有意义的字段(我在 AWS EC2 EBS 卷控制台中看到的),请参阅下图显示了 AWS 控制台中的可用字段。

我在 Github, which seems like it can print some more fields, but it's giving another error listed below. I successfully ran python -m pip install --user aws or python -m pip install aws or pip install aws, or ran the script (which included lines only after #Import classes from aws package line 上在线找到了另一个脚本 (#2),位于他存储库的 aws 文件夹中(克隆后),但仍然出现错误。

import boto.ec2
class Volumes:
    def __init__(self):
        ''' Volumes Constructor '''

    def list_volumes(conn):
        ''' List Volumes '''
        # get all volumes
        vols = conn.get_all_volumes()

        # if volumes found
        if vols:
            #loop through volumes
            for v in vols:
                print 'Volume Id:', v.id
                print 'Volume Status:', v.status
                print 'Volume Size:', v.size
                print 'Zone:', v.zone
                print 'Volume Type:', v.type
                print 'Encrypted:', v.encrypted

                #print attachment set object
                attachmentData = v.attach_data
                print 'Instance Id:', attachmentData.instance_id
                print 'Attached Time:', attachmentData.attach_time
                print 'Device:', attachmentData.device
                print '**********************************'

#Import classes from aws package
from aws import Connection
from aws import EC2Instance
from aws import Volumes
#import aws

connInst = Connection()
conn = connInst.ec2Connection()

#instantiate Volumes and list volumes
volumeInst = Volumes()
volumeInst.list_volumes(conn)

脚本 # 2 错误是:

Traceback (most recent call last):
  File "/Users/arun/aws-vol-info2.py", line 30, in <module>
    from aws import Connection
ImportError: cannot import name Connection

如果我在脚本# 2 中注释 from aws ... .. 和 use/uncomment import aws 行,那么我得到的是:

Traceback (most recent call last):
  File "/Users/arun/aws-vol-info2.py", line 35, in <module>
    connInst = Connection()
NameError: name 'Connection' is not defined

我认为您正在寻找 vol.volume_type。您可以在 ec2.Volume 此处查看完整的属性列表: http://boto3.readthedocs.io/en/latest/reference/services/ec2.html#volume

可以增强此脚本以显示更有意义的信息,但使用 jpavs 的提示,我想出了此脚本 ~/aws-vol-info.py:

import boto3

# Define the connection
ec2 = boto3.resource('ec2', region_name="us-west-2")

# Find all volumes
volumes = ec2.volumes.all()

# Loop through all volumes and pass it to ec2.Volume('xxx')
for vol in volumes:
    iv = ec2.Volume(str(vol.id))
    print "Created(" + str(iv.create_time) + "),AZ(" + str(iv.availability_zone) + "),VolumeID(" + str(iv.volume_id) + "),VolumeType(" + str(iv.volume_type) + "),State(" + str(iv.state) + "),Size(" + str(iv.size) + "),IOPS(" + str(iv.iops) + "),IsEncrypted(" + str(iv.encrypted) + "),SnapshotID(" + str(iv.snapshot_id) + "),KMS_KEYID(" + str(iv.kms_key_id) + ")",

    # The following next 2 print statements variables apply only in my case.
    print ",InstanceID(" + str(iv.attachments[0]['InstanceId']) + "),InstanceVolumeState(" + str(iv.attachments[0]['State']) + "),DeleteOnTerminationProtection(" + str(iv.attachments[0]['DeleteOnTermination']) + "),Device(" + str(iv.attachments[0]['Device']) + ")",
    if iv.tags:
        print ",Name(" + str(iv.tags[0]['Name']) + "),Mirror(" + str(iv.tags[0]['mirror']) + "),Role(" + str(iv.tags[0]['role']) + "),Cluster(" + str(iv.tags[0]['cluster']) + "),Hostname(" + str(iv.tags[0]['hostname']) + "),Generation(" + str(iv.tags[0]['generation']) + "),Index(" + str(iv.tags[0]['index']) + ")"
    print ""

运行: python ~/aws-vol-info.py 它为我提供了 python 脚本中提到的所有字段的 CSV 格式值。很少 (2-3) 个 AWS 控制台字段丢失,因为库不提供这些字段,但无论我从上面得到什么,或者如果我深入研究 iv.attachments[0]['<somekey>']iv.tags[0]['<somekey>'] 对我来说就足够了这次

PSiv.attachmentsiv.tags都是iv对象中的List/dictionary类型变量,因此您可以通过显示您想要从中获取的确切内容来增强脚本。因此,如果你想要 InstanceID 那么你可以使用这个:str(iv.attachments[0]['InstanceId']) 来打印它。

要获得更好的版本:请在此处查看 .python 脚本:
