For complete flow, reference this tutorial in Connection Hub Wiki.

To connect a physical instance (connection hub member) to a cloud instance (connection hub host), these steps should be followed respectively:

• Setting up connection hub in cloud instance
  • by installing operator
  • by creating connection hub resource
  • continue if connection hub is ready to operate
• Registering a physical instance to cloud instance
  • by creating physicalinstances.connection-hub.roboscale.io/v1alpha1 custom resource
• Sending installer script to physical instance and executing
• Waiting for physical instance to be connected to cloud instance
  • by watching connectionhubs.connection-hub.roboscale.io/v1alpha1 custom resource
  • continue if connection hub is connected over multicast and waiting for credentials
• Add physical instance credentials to physicalinstances.connection-hub.roboscale.io/v1alpha1 custom resource in cloud instance
