[英]How to start all the ec2 instances using python by configuring boto3 libraries in windows?
我在Windows 8.1 64位计算机上安装了python 3.6.4版本。 安装和配置boto3和boto库所需的所有步骤是什么? 我试图获取特定区域的所有AWS EC2实例并停止它们,但无法执行任务。
是否有人有解决方案来满足要求。
将凭证添加到环境变量: 用于配置凭证的文档
import boto3
client = boto3.client('ec2',region_name='us-west-2') #Add your region
print('Loading function')
def lambda_handler(event, context):
responses = client.start_instances(
InstanceIds=[
'YOUR INSTANCE IDs'
],
DryRun=True # Make it False to test
)
#Basic import boto3 libraries
import boto3
import sys
#provided Access Credentialsaccess_key
access_key = ""
secret_key = ""
count=0
#Establish a connection to EC2 resource using credentials and region_name
conn = boto3.resource('ec2', aws_access_key_id=access_key, aws_secret_access_key=secret_key,region_name='us-west-1')
print("Argument length: ",len(sys.argv))
if len(sys.argv)>2:
Keyname = sys.argv[1]
value = sys.argv[2]
instances = conn.instances.filter(Filters=[{'Name': 'instance-state-name', 'Values': ['stopped'],'Name': 'tag:'+Keyname,'Values': [value]}])
print("Arguments passed\nKey: "+Keyname+"\nValue: "+value)
else:
instances = conn.instances.filter(Filters=[{'Name': 'instance-state-name', 'Values': ['stopped']}])
for instance in instances:
#instance.start(instance.id)
count+=1
print(instance.id,",",instance.state["Name"])
print("Total number of EC2 instances are stopped on cloud: ",count)
上面的代码可以用2个参数执行,第一个是所有实例的Tag Key,第二个是Tag Value。 它将获取所有使用给定值标记的运行实例,并逐一启动它们。
