How Google Anthos in Action covers it
- How deep it goes
- Defines configuration, Pod assignment, and node-pool restriction, but does not detail the underlying CNI implementations.
- Examples
- Uses IPvlan with Whereabouts IPAM and assigns two named networks through a Deployment annotation.
- What it assumes
- Requires multi-NIC capability enabled on the cluster and available node interfaces supporting the selected CNI configuration.
- What you can do after
- Configure additional networks and attach them to selected Pods or Deployments.
- How it connects
- Connects Multus CNI, Pod networking, CNI plugins, IPAM, node pools, and Anthos bare metal clusters.
