Network Role Develop (Migration)

[SuperPanda]

1. Network Role Development

Objective:
Develop a comprehensive network role that includes Open vSwitch (openvswitch) and its associated bridges (ovs_bridge). This role will serve as the central point for network configurations within the Orchestration Architect framework.

Key Components:

• openvswitch: Manages the main Open vSwitch configurations, taking a list of openvswitch_bridges.
• ovs_bridge: Configures individual bridges within Open vSwitch, including ports, interfaces, VLAN IDs, and other related settings.

Tasks:

• Develop openvswitch Role:

  • Create a present, absent, and info state for Open vSwitch.
  • Define parameters for openvswitch_bridges, allowing dynamic configuration of multiple bridges.

• Develop ovs_bridge Role:

  • Create present, absent, and info states for configuring OVS bridges.
  • Ensure the role handles ports, interfaces, and VLAN configurations.

• Integrate with Network Role:

  • Ensure the network role can dynamically call the openvswitch and ovs_bridge roles based on the provided specifications.

Requirements:

• Ensure compatibility with mTLS configurations.
• Support dynamic updates and changes to network configurations via Ansible playbooks.
• Document usage and provide examples in the network role README.

2. OA001 System Recreation and Testing

Objective:
Recreate OA001 (System Master Control Node) with improved processes for managing subvolumes, ensuring that even with the same filesystem and partition name, subvolumes can be moved or replicated without issues.

Tasks:

• Rebuild OA001:

  • Use the latest backups and specification files to reconstruct OA001.
  • Implement a process for testing the movement of USB-based systems with consistent subvolume management.

• Develop Playbook for USB and Subvolume Management:

  • Create a playbook that handles the movement of USB devices, ensuring subvolume consistency across different systems.
  • Integrate device map handling to create predictable names for subvolumes and devices.

Requirements:

• Ensure seamless transition and consistency when moving USB devices between systems.
• Test with different filesystems and partition names to validate robustness.
• Provide detailed documentation for the process, including troubleshooting steps.

3. CI/CD Pipeline and Playbook Execution in Containers

Objective:
Establish a CI/CD pipeline that efficiently runs playbooks within containers, leveraging tools like SSH and Open vSwitch for network configurations.

Tasks:

• CI/CD Pipeline Setup:

  • Define a clear process for integrating playbook execution into a CI/CD pipeline.
  • Use containers (via systemd-nspawn or Docker) to run playbooks in isolated environments.

• Containerized Playbook Execution:

  • Develop roles or playbooks that set up containers with necessary tools (SSH, Open vSwitch) for running playbooks.
  • Ensure containers are configured to support automated testing and deployment processes.

• Open vSwitch Integration:

  • Integrate Open vSwitch into the CI/CD pipeline to manage container networking.
  • Test mTLS-secured connections within the CI/CD environment.

Requirements:

• Ensure the pipeline is scalable and can handle multiple playbooks and roles concurrently.
• Automate the process to reduce manual intervention, including handling failures and retries.
• Document the CI/CD setup, including step-by-step guides for configuration and maintenance.

4. GPG Key Management

Objective:
Set up a GPG key management system with a focus on long-term master keys and intermediate keys for daily operations.

Tasks:

• Develop GPG Key Role:

  • Implement a gpg_key role that handles the creation, storage, and management of GPG keys.
  • Ensure the role can differentiate between master and intermediate keys, with the master key designed to last indefinitely.

• Document Key Management Strategy:

  • Write a README outlining the key management process, including scenarios for key loss, rekeying, and expiration.
  • Provide examples for generating, storing, and using GPG keys within the Orchestration Architect framework.

Requirements:

• The master key should have no expiration, minimizing disruption in case of key loss.
• Intermediate keys should be rekeyed periodically or on-demand to enhance security.
• Ensure keys are stored securely, with the option to use air-gapped systems for sensitive operations.

5. Finalization of nspawn and QEMU Runner Roles

Objective:
Finalize the nspawn_runner and qemu_runner roles, ensuring they are fully integrated into the parent container role and support the ephemeral execution.

Tasks:

• Complete Runner Roles:

  • Finalize the implementation of present, absent, info, and rekey states for both nspawn_runner and qemu_runner.
  • Ensure integration with storage and network roles for seamless container/VM creation and management.

• Create Example Playbooks:

  • Develop playbooks that demonstrate the usage of nspawn_runner and qemu_runner, focusing on ephemeral container/VM execution.
  • Include scenarios for snapshotting, rolling back, and dynamically configuring containers/VMs.

Requirements:

• Ensure that both runner roles support dynamic configuration based on input parameters.
• Integrate snapshot management for both nspawn and QEMU, allowing for quick rollbacks.
• Document the role usage, including configuration options and examples.

Additional Ideas for USB and Subvolume Management

Objective:
Develop a robust playbook to manage subvolumes on USB devices, ensuring consistency and predictability across different systems.

Tasks:

• Subvolume Naming and Management:

  • Implement device map handling to create predictable names for subvolumes, even with the same filesystem and partition name.
  • Develop a playbook to automate the movement of subvolumes between systems, ensuring they retain their integrity.

• Testing and Validation:

  • Test the process across multiple systems, verifying that subvolumes can be moved without issues.
  • Document any edge cases or challenges encountered during testing.

Requirements:

• Ensure that the playbook can handle various scenarios, including different filesystem types and partition configurations.
• Provide a clear process for troubleshooting and resolving subvolume-related issues.
