通过VPC ID过滤LoadBalancer [英] Filter LoadBalancer By VPC ID

问题描述

我有两个与两个不同的VPC相关联的负载均衡器.

I have two loadbalancers associated with two different VPC.

我能够使用AWS CLI列出所有负载均衡器.

I am able to list all loadbalancers using AWS CLI.

现在，我需要在特定VPC中检索负载均衡器的名称.可以通过AWS CLI完成吗?

Now I need to retrieve the name of the loadbalancer in a particular VPC. Is it can be done via AWS CLI ??

推荐答案

确实，ELB服务没有提供服务方对结果的过滤.但是，您无需编写脚本即可获得所需的内容.您可以使用AWSCLI的内置jmespath查询功能.

It is true that the ELB service provides no service side filtering of results. However, you don't need to write a script to get what you want. You can use the built-in jmespath querying capability of AWSCLI.

$ aws elb describe-load-balancers --query 'LoadBalancerDescriptions[?VPCId==`vpc-12345678`]|[].LoadBalancerName'
[
    "elb1", 
    "elb2"
]
$

应仅返回vpc-12345678中的负载均衡器名称列表.

Should return only a list of names of load balancers that are in vpc-12345678.
