boto3 aws api-列出可用的实例类型 [英] boto3 aws api - Listing available instance types
问题描述
实例类型:(t2.micro,t2.small,c4.large ...)此处列出的实例类型: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html
Instance types: (t2.micro, t2.small, c4.large...) those listed here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html
我想通过boto3访问这些列表. 像这样:
I want to access a list of these through boto3. something like:
conn.get_all_instance_types()
甚至
conn.describe_instance_types()['InstanceTypes'][0]['Name']
在这个怪异的api中一切看起来都像这样.
which everything seems to look like in this weird api.
我已经查看了有关client和ServiceResource的文档,但找不到任何似乎接近的东西. 我什至还没有找到一种骇人听闻的解决方案,该解决方案列出了恰好代表所有实例类型的其他内容.
I've looked through the docs for client and ServiceResource, but i can't find anything that seems to come close. I haven't even found a hacky solution that lists something else that happen to represent all the instance types.
有人对boto3有更多的经验吗?
Anyone with more experience of boto3?
推荐答案
现在有boto3.client('ec2').describe_instance_types()
和相应的aws-cli命令aws ec2 describe-instance-types
:
There's now boto3.client('ec2').describe_instance_types()
and corresponding aws-cli command aws ec2 describe-instance-types
:
'''EC2 describe_instance_types usage example'''
import boto3
def ec2_instance_types(region_name):
'''Yield all available EC2 instance types in region <region_name>'''
ec2 = boto3.client('ec2', region_name=region_name)
describe_args = {}
while True:
describe_result = ec2.describe_instance_types(**describe_args)
yield from [i['InstanceType'] for i in describe_result['InstanceTypes']]
if 'NextToken' not in describe_result:
break
describe_args['NextToken'] = describe_result['NextToken']
for ec2_type in ec2_instance_types('us-east-1'):
print(ec2_type)
大约需要3秒钟的运行时间.
Expect about 3s of running time.
