Networking

Configure VPC, public IPs, KloudLB load balancers, and firewall profiles.

Networking

Networking covers how your clusters talk privately and how traffic reaches the public internet: VPC, public IPs, KloudLB, and Firewall profiles for traffic rules on public addresses.

Building blocks

  • VPC: private network boundary for cluster traffic
  • Public IPs: addresses for nodes or load-balancer VIPs
  • KloudLB: provisions an external address when you create a LoadBalancer Service
  • Firewall: reusable allow/deny profiles attached to public IPs

When to use it

  • Isolate cluster traffic in a VPC
  • Expose HTTP, gRPC, or TCP apps without managing your own L4 appliance
  • Restrict who can reach public endpoints with firewall profiles

In the portal

  1. Open Networking.
  2. Create or review a VPC for your clusters.
  3. Allocate public IPs when you need external reachability.
  4. Configure Firewalls for the ports you intend to expose.
  5. In-cluster, create a Service type: LoadBalancer; KloudLB assigns a VIP from the IP pool.
