Description

This check ensures that the container in the Deployment has argument request timeout set as appropriate.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.deployment_container_argument_request_timeout_appropriate

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run kubernetes_compliance.control.deployment_container_argument_request_timeout_appropriate --share

SQL

This control uses a named query:
