Load Balancers are essential when running a service. They expose the containers and images in which your application resides. When your containers are run inside a private network, you need a load balancer to listen on the correct ports to access the application.
If you need to create an Ingress Load Balancer, refer to the page in the DuploCloud Kubernetes User Guide.
Add a Load Balancer listener that uses the Kubernetes NodePort (K8S NodePort).
Several Load Balancers are available for Azure. See the for a comparison of each option.
Application LB (Standard load balancer)
Shared App Gateway
Classic (Basic load balancer)
Health Check - Selecting this load balancer allows the Application LB (Standard load balancer) to use Kubernetes Health Check to determine whether your service is running properly.
You must create before adding load balancers and listeners.
In the DuploCloud Portal, navigate Kubernetes -> Services.
On the Services page, select the Service name in the Name column.
Click the Load Balancers tab.
Click Configure Load Balancer. The Add Load Balancer Listener pane appears.
Select a type (such as K8S Node Port) in the Select Type field.
Add the Kubernetes Health Check URL for this container in the Health Check field.
Complete the other fields in the Add Load Balancer Listener and click Add.
Rules specify specific configurations for various types of Load Balancers.
Restrict open access to your public Load Balancers by enforcing controlled access policies.
From the DuploCloud Portal, navigate to Administrator -> System Settings.
Select the System Config tab, and click Add. The Add Config pane displays.
From the Config Type list box, select Flags.
From the Key list box, select Deny Open Access To Public LB.
In the Value list box, select True.
Click Submit. Open access to public Load Balancers is restricted.
See the use case for an example of how to configure Load Balancers using rules.
