[Doc] Allow configuring tolerations and nodeSelector for importer pods

We want to be able to configure the tolerations and nodeSelector of the importer pods spawned in a migration.

This is needed when we need to select certain nodes that have access to the migration network or when the nodes have a taint.

Discover

In this initial stage, users become aware of the new feature and its relevance to their needs.

• Release Notes: Highlight the new feature in the release notes of the Migration Toolkit for Virtualization version 2.9. This should include a brief overview of what tolerations and nodeSelector are, and why they are important for managing pod scheduling in Kubernetes.

Learn

In this stage, users seek to understand how the feature works and its implications.

• Detailed Documentation: Provide comprehensive documentation that explains:
  • What tolerations and nodeSelector are.
  • How to configure these settings for importer pods in MTV.
  • Use cases and scenarios where this feature is beneficial.
• Tutorials and Guides: Develop step-by-step tutorials that guide users through the configuration process, including examples and best practices.
• FAQs: Create a Frequently Asked Questions section addressing common queries related to the new feature.

Try

This stage encourages users to experiment with the new feature in a controlled environment.

• Hands-On Lab: Offer a hands-on lab or sandbox environment where users can practice configuring tolerations and nodeSelector for importer pods without affecting their production systems.
• Sample Configurations: Provide sample YAML configurations that users can modify and test in their environments.
• Video Demos: Create video demonstrations showing the configuration process and the impact of using tolerations and nodeSelector.

Adopt

In this stage, users begin to implement the feature in their production environments.

• Implementation Guides: Offer detailed implementation guides that outline the steps for integrating the new feature into existing workflows.
• Case Studies: Share case studies or success stories from users who have successfully adopted the feature, highlighting the benefits they experienced.
• Support Resources: Ensure that users have access to support resources, including community forums, support tickets, and contact information for technical assistance.

Expand

The final stage focuses on encouraging users to explore additional features and capabilities of MTV.

• Advanced Configuration Options: Document advanced configurations and scenarios that leverage tolerations and nodeSelector, encouraging users to explore more complex setups.
• Integration with Other Features: Highlight how this feature interacts with other MTV features, promoting a holistic understanding of the toolkit.
• Feedback Mechanism: Implement a feedback mechanism for users to share their experiences and suggestions for further improvements, fostering a community-driven approach to documentation.

By following this structured content journey, users can effectively discover, learn, try, adopt, and expand their use of the new feature in the Migration Toolkit for Virtualization, ensuring a smooth transition and enhanced user experience.

Why is this content important?

The content journey for the new feature allowing the configuration of tolerations and nodeSelector for importer pods in the Migration Toolkit for Virtualization (MTV) is crucial for several reasons:

Enhances User Understanding

Providing a structured content journey helps users understand the significance of the new feature. By breaking down complex concepts like tolerations and nodeSelector into digestible parts, users can grasp how these elements affect pod scheduling and resource management in Kubernetes. This understanding is essential for effective implementation.

Facilitates Adoption

A well-defined content journey encourages users to adopt the new feature confidently. By guiding them through the stages of discovery, learning, trying, and adopting, users are less likely to feel overwhelmed. This structured approach reduces the learning curve and promotes a smoother transition to using the new capabilities.

Promotes Best Practices

Through detailed documentation, tutorials, and case studies, users are exposed to best practices for configuring tolerations and nodeSelector. This not only helps them implement the feature correctly but also ensures they maximize its benefits, leading to improved performance and resource utilization in their environments.

Encourages Experimentation

The "Try" stage of the content journey provides users with opportunities to experiment in a safe environment. This hands-on experience is vital for building confidence and familiarity with the new feature, allowing users to explore its capabilities without the risk of impacting their production systems.

Builds Community and Support

By incorporating feedback mechanisms and support resources, the content journey fosters a sense of community among users. This engagement can lead to valuable insights, shared experiences, and collaborative problem-solving, enhancing the overall user experience and satisfaction with the MTV.

Drives Continuous Improvement

The structured approach to documentation encourages ongoing improvement of the content based on user feedback and evolving needs. This adaptability ensures that the documentation remains relevant and useful, keeping pace with changes in technology and user expectations.

In summary, the content journey is essential for empowering users to effectively utilize the new feature in MTV. It enhances understanding, facilitates adoption, promotes best practices, encourages experimentation, builds community, and drives continuous improvement, ultimately leading to a more successful user experience.

What is the main user goal aka job to be done?

1. As an OpenShift Administrator, I want to configure tolerations for importer pods so that I can ensure they are scheduled on nodes that can handle specific workloads without resource contention.

1. As a DevOps Engineer, I want to set nodeSelector for importer pods so that I can control their placement on nodes with the required hardware specifications, optimizing performance and resource allocation.

1. As a Cloud Architect, I want to understand how to effectively use tolerations and nodeSelector so that I can design a more efficient and resilient Kubernetes cluster that meets application demands.

1. As a System Operator, I want to validate the configuration of tolerations and nodeSelector in a test environment so that I can ensure the settings work as intended before applying them in production.
