Enhancement: Implement Chaos Experiments for Secrets, Volumes, Services

[see-quick]

Description

Introduce chaos experiments in Chaos Mesh to test resilience by deleting Kubernetes objects like Secrets, Volumes, Services, etc. This feature simulates accidental losses, enhancing fault tolerance and recovery strategies.

Motivation

• Test application resilience and recovery from the loss of Kubernetes objects.
• Validate fault tolerance against accidental or malicious deletions.

Proposed Functionality

• Target Selection: Users can specify Kubernetes objects (e.g., Secrets, Volumes) for deletion.
• Selective Deletion: Target objects by name or labels for precise testing.
• Schedule Deletions: Support for timed, random, and periodic deletion events.
• Safety Measures: Safeguards to prevent unintended critical deletions.
• Recovery Testing: Assess automatic or manual recovery processes.

Use Cases

1. Secrets Deletion: Evaluate application response to losing configuration secrets.
2. Volumes Deletion: Test stateful application resilience by deleting persistent volumes.
3. Services Disruption: Assess the impact on networking and service discovery with service deletions.

Open Questions

• Ensuring safety and recovery in user environments during tests.
• What mechanisms can be implemented to quickly restore deleted objects if needed?
• Does Chaos Mesh want to support such functionality?

This proposal aims to broaden Chaos Mesh's capabilities for more comprehensive resilience testing by simulating the deletion of key Kubernetes components.
