AWS ssm send-command : modify timeout in CLI

Question

I'm using AWS SSM to compute a long script on an ec2 instance.

I would like to configure the execution timeout (execution time, not launch time) and I don't find how to do this on the official documentation (opposing informations or not working).

I'm using only the CLI interface.

Answer 1

This value is a document property that can be passed with --parameters option using executionTimeout key. You can use aws ssm describe-documents to find this and other document specific parameters.

aws ssm describe-document --name "AWS-RunShellScript"
