How do you document decisions and architecture for DaemonSets?

Documenting decisions and architecture for DaemonSets is critical for maintaining clarity and ensuring that all stakeholders understand the rationale behind certain implementations and configurations. Below is an outline of how to effectively document these aspects:

Key Components of Documentation

  • Rationale: Explain why a DaemonSet is being used in your architecture. Discuss specific use cases and benefits.
  • Design Decisions: Detail the decisions made during the implementation, including alternative options considered and reasons for the final choice.
  • Configuration: Provide examples of configurations used in the DaemonSet, including annotations and labels that are critical for its operation.
  • Monitoring and Logging: Explain how monitoring is set up for the DaemonSet and any relevant logging practices.
  • Updates and Maintenance: Document any unique procedures around updating and maintaining the DaemonSet.

Example of a DaemonSet Configuration
