The Vultr Cloud Controller Manager (CCM) is a critical component that allows Kubernetes clusters on Vultr to natively integrate with Vultr’s cloud infrastructure. By running as a controller inside your cluster, the CCM bridges Kubernetes APIs with Vultr services, enabling features such as:
- Automated Load Balancing: Provision and manage Vultr Load Balancers directly from Kubernetes Service objects, with traffic automatically routed to your pods.
- Persistent Storage Management: Dynamically provision and attach Vultr Block Storage volumes using the Container Storage Interface (CSI), ensuring persistent volumes are correctly integrated with pods.
- Networking Integration: Automate network configuration for cluster nodes, including private networking and VPC assignments, directly from Kubernetes resources.
- Cloud-Aware Scheduling: Expose node metadata and labels to the scheduler, allowing Kubernetes to make intelligent placement decisions based on Vultr instance types, regions, and availability.
