无法按标记筛选描述实例

Question

无法按标记筛选实例并获取实例列表。请帮助我如何继续

import boto3
ec2 = boto3.resource('ec2')
def lambda_handler(event, context):
    # Use the filter() method of the instances collection to retrieve
    # all running EC2 instances.
    filters = [{'Name':'OS_Name', 'Values':['Rstudio']}]  
    #filter the instances
    instances = ec2.instances.filter(Filters=filters)
    #locate all running instances
    RunningInstances = [instance.id for instance in instances] 
    #print the instances for logging purposes
    #print RunningInstances  
    #make sure there are actually instances to shut down. 
    if len(RunningInstances) > 0:
        #perform the shutdown
        shuttingDown = ec2.instances.filter(InstanceIds=RunningInstances).stop()
        print (shuttingDown)
    else:
        print ("Nothing to see here")

Answer 1

您需要指定过滤器的类型，因此在本例中它将是tagfilters = [{'Name':'tag:OS_Name', 'Values':['Rstudio']}]

从boto3文件

标记：-分配给资源的标记的键/值组合。使用过滤器名称中的标记键和标记值作为过滤器值。例如，要查找具有键所有者和值TeamA的标记的所有资源，请指定tag:Owner for 筛选器名称和筛选器值的TeamA
