I want to register a Lambda function as a target behind my Application Load Balancer using the AWS Command Line Interface (AWS CLI). How can I do this?
Note: If you receive errors when running AWS CLI commands, make sure that you’re using the most recent AWS CLI version.
1. Create a target group with the target type set to Lambda. Be sure to replace [your target group name] with the name of your target.
aws elbv2 create-target-group \
--name [your target group's name] \
2. Use the add-permission command to allow Elastic Load Balancing to invoke your Lambda function. Be sure to replace [your Lambda function's name] and [your target group's Amazon Resource Name (ARN)] with your respective names.
aws lambda add-permission \
--function-name [your Lambda function's name] \
--statement-id load-balancer \
--principal elasticloadbalancing.amazonaws.com \
--action lambda:InvokeFunction \
--source-arn [your target group's Amazon Resource Name (ARN)]
3. Use the register-targets command to register Lambda as the target. Be sure to replace [your target group's ARN] and **[your Lambda function's ARN]**with your ARNs.
aws elbv2 register-targets \
--target-group-arn [your target group's ARN] \
--targets Id=[your Lambda function's ARN]
