    - Creating an Operator from scratch using Go.
    - Automating recurring tasks (e.g., backups, upgrades).
    - Managing and scaling stateful applications.

- Kubernetes Integrations
    - Connecting applications and services with Operators.
    - Leveraging external APIs and services within Kubernetes.

- Integration of Admission Webhooks

    - Security aspects of Admission Webhooks.

- Testing and Debugging Operators
    - Automated testing of Operators.
    - Status updates and events.
    - Monitoring and metrics.
    - Testing and debugging.
    - Deployment and lifecycle.

    - Tips for stable and maintainable Operators.
    - Efficient structuring and documentation of code.

Disclaimer: The actual course content may vary from the above, depending on the trainer, implementation, duration and constellation of participants.

Whether we call it training, course, workshop or seminar, we want to pick up participants at their point and equip them with the necessary practical knowledge so that they can apply the technology directly after the training and deepen it independently.
