Networking
Networking on Kloude covers how clusters talk privately and how traffic reaches the internet: VPC, public IPs, KloudLB, and Firewall profiles. Use this page when you create a VPC, allocate a public address, or jump into firewall profiles from the same hub.
The portal Networking section has three tabs: Virtual Private Network, Public IP addresses, and Firewalls.
What you see in the panel
On Virtual Private Network, create a VPC with + Create VPC, search by name or CIDR, and review region, status (for example In use), linked cluster, and created time.
On Public IP addresses, search by address or reference id, filter by type, and review hourly cost and created time. Attach firewall profiles to public IPs before you open production ports.
On Firewalls, create profiles and open them to edit rules. Deep rule editing lives on the Firewall page.
Components
A VPC is the private network range for cluster and microservice traffic. A public IP is an address for a node or load balancer VIP. KloudLB assigns an external address when you create a Service of type LoadBalancer. A firewall profile is the allow/deny set you attach to public IPs.
When to use it
Use Networking to isolate cluster traffic in a VPC, expose HTTP, gRPC, or TCP apps without running your own layer-4 appliance, and limit access to public endpoints with a firewall profile.
Tutorial: VPC, public IP, then LoadBalancer
Open Networking
From the sidebar, open Networking. Stay on Virtual Private Network first.
Create or verify a VPC
Click + Create VPC (or confirm an existing VPC is In use and linked to your cluster). Pick a clear name and a private CIDR that does not collide with other networks you peer with.
Allocate a public IP if needed
Switch to Public IP addresses. Allocate or locate the address your app will use. In shared notes, prefer placeholders such as 203.0.113.10. Never paste live customer IPs into public docs.
Attach firewall rules
Open Firewalls, create or edit a profile, and attach it to the public IP. See the full rule tutorial on Firewall.
Create a LoadBalancer Service
In the cluster, create a Service with type: LoadBalancer. KloudLB assigns a VIP from the IP pool.
apiVersion: v1
kind: Service
metadata:
name: example
spec:
type: LoadBalancer
ports:
- port: 80
targetPort: 8080
selector:
app: example
Least privilege:
Do not open wide port ranges when a single service port is enough. Revisit profiles whenever you create a new LoadBalancer Service.
