Is it possible to configure retries with the AWS CLI?

I have a script which uses the AWS CLI (currently v1.11.90) to coordinate various AWS resources. Amongst other things it calls aws cloudformation list-stacks three or four times in a row.

I fairly frequently get errors because my requests are being throttled:

An error occurred (Throttling) when calling the ListStacks operation (reached max retries: 4): Rate exceeded

In particular if I happen to have the CloudFormation console open in my browser this happens pretty reliably.

I would like to configure it to be more forgiving in these cases -- either to back off more aggressively, or to retry more times. I've tried to find a way of doing this and have seen a few references to being able to do it in boto, but I can't see how to do it via the CLI.

The other answers are good, but to answer the precise question: yes, define environment variable AWS_MAX_ATTEMPTS

See https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html

Seems you're using ListStack for cloudformation service maybe implementing a polling and retry, a simpler solution is now built into the CLI for this: aws <service> wait <condition> so the polling is already implemented.

$ aws cloudformation wait stack-exists --stack-name <name of the stack>

If you are creating some resources and waiting for that one to create successfully, AWS cli provided wait module[1] Since you want to retry for an error you can do a retry using while or until. Below code will run until command is successful.

while [ $? -ne 0 ]; do
YOUR COMMAND
GOOD CONDITION TO EXIT AFTER SOME RETRIES 
done

Make sure that you are using a good condition to exit after some retries otherwise it will end up with a infinite loop.
