如何通过 boto3 获取 AWS 的配额？

Question

I'm working on boto3 - SDK python for AWS.

I am starting with simple service quota for ec2 but always ending up with the below error,

import boto3

quota_client = boto3.client('service-quotas')
response = quota_client.get_service_quota(
ServiceCode='ec2'
)

Error:

quotas'. Valid service names are: acm, acm-pca, alexaforbusiness,

The documentation page shows that service-quotas supported in boto3 but looks like it's not or am I doing anything incorrect here?

Answer 1

I could reproduce the problem with my current boto3-1.9.174 botocore-1.12.174 installation.

I then did:

pip install boto3 --upgrade

It moved me to version boto3-1.9.208 botocore-1.12.208 and it works fine.

I try to use Python virtual environments to isolate libraries for easy updating.
