AWS CLI: Not able to filter describe-rules

I am trying to get the list of listener rules based on a filter as described here: https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-output.html

Below is my command:

aws elbv2 describe-rules \
--listener-arn arn:aws:elasticloadbalancing:us-east-1:34555433333:listener/app/ApplicationLoadBalancer/a333ddsdsddsds/22assds3dasfd \
--filters "TargetGroupArn==arn:aws:elasticloadbalancing:us-east-1:34555433333:targetgroup/TG-Test-111111111/ass22dss2dkk" \
--query 'Rules[].RuleArn'

when I run it I keep getting: Unknown options: --filters, TargetGroupArn==

Try something like:

aws elbv2 describe-rules --listener-arn 'arn:aws:elasticloadbalancing:us-east-1:34555433333:listener/app/ApplicationLoadBalancer/a333ddsdsddsds/22assds3dasfd' \
  --output text \
  --query "Rules[].{RuleArn: RuleArn, Actions:Actions[?TargetGroupArn=='$targetGroupArn'].TargetGroupArn }" | grep -B 1 ACTIONS | grep -v ACTIONS

you'll get the RuleArn in text format. Without the grep, you will get something like:

arn:aws:elasticloadbalancing:us-east-1:34555433333:listener-rule/app/loadbalancer/a333ddsdsddsds/22assds3dasfd/22assds3dasfs
ACTIONS arn:aws:elasticloadbalancing:us-east-1:34555433333:targetgroup/tg/34555433333

grep removes the unwanted lines.

Adiii is correct to point out that the filter option isn't supported here, however, as the query option is always available, you can get what you want from it, TargetGroupArn included.

So with some digging in JEMSPath, the basic solution is:

aws elbv2 describe-rules --listener-arn arn:aws:elasticloadbalancing:us-east-1:34555433333:listener/app/ApplicationLoadBalancer/a333ddsdsddsds/22assds3dasfd --query 'Rules[].{RuleArn: RuleArn, Actions: Actions[?TargetGroupArn==`arn:aws:elasticloadbalancing:us-east-1:34555433333:targetgroup/TG-Test-111111111/ass22dss2dkk`]}|[].RuleArn'

If you want to get a list of listener rule you can use query, is there any need of filter with query? 

aws elbv2 describe-rules --listener-arn arn:aws:elasticloadbalancing:us-east-1:34555433333:listener/app/ApplicationLoadBalancer/a333ddsdsddsds/22assds3dasfd --query 'Rules[].{Priority:Priority,Host:Conditions[0].Values[0]}'

This will return all rule under listener and will return host and priority.

  {
        "Priority": "1",
        "Host": "test.example.com"
  }

or to get Just ARN of rule

aws elbv2 describe-rules --listener-arn arn:aws:elasticloadbalancing:us-east-1:34555433333:listener/app/ApplicationLoadBalancer/a333ddsdsddsds/22assds3dasfd --query 'Rules[].RuleArn'

As aws elbv2 describe-rules does not have an option for the filter that is why you got Unknown options: --filters

  describe-rules
[--listener-arn <value>]
[--rule-arns <value>]
[--page-size <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

describe-rules

So workaround can list all the rule and grep your desired target group which is attached to rule.

aws elbv2 describe-rules --listener-arn arn:aws:elasticloadbalancing:us-west-2:060558051165:listener/app/Prod-Main-Delaers/11a84cfee3fc1e29/37fb4adb7314bac0 | grep -A6 -B6 targetgroupARN
