Execute Kubernetes Manifest
Overview
The Execute Kubernetes Manifest action allows users to execute Kubernetes commands (kubectl) that directly operate on YAML manifest files within a specified Kubernetes cluster. This action is particularly useful for applying, creating, deleting, or replacing resources based on provided or AI-generated Kubernetes manifests. It enables users to perform quick actions on their clusters related to security and other critical operations, making it ideal for managing, securing, and deploying configurations directly from the bot workflow.
Prerequisites
- Agent Configuration:
Ensure the Linux Agent is configured. Refer to the Agent Installation Guide. - kubectl CLI installed on the Linux agent. You can refer to the official installation guide for setup instructions.
- Access to the target Kubernetes cluster.
