How to enable load balancing algoithm in openshift route ?

  1. If you are calling your pod externally it goes from Router to Service to Pod. If annotation is not set to true on the Router, service always forwards to the same pod.Also after disabling sticky routing with annotation above you can select a loadbalancing algorithm with: as key and one of [source,roundrobin,leastconn] as value

To enable load balancing algorithms in OpenShift routes, you typically don’t configure the load balancing algorithm directly within OpenShift itself. Instead, OpenShift relies on the underlying infrastructure, such as the Kubernetes Ingress Controller or the configured cloud provider’s load balancer.In Kubernetes/OpenShift, the default load balancing algorithm is typically Round Robin. However, if you need to customize the load balancing algorithm, you would typically configure it at the level of the load balancer or Ingress Controller being used.Here’s a general outline of how you might approach this:

  1. Check the Load Balancer Configuration: If you’re using a cloud provider’s load balancer (like AWS ELB, Google Cloud Load Balancer, etc.), check the documentation provided by the cloud provider to see if they offer options to configure load balancing algorithms.

  1. Customize the Ingress Controller: If you’re using an Ingress Controller (like Nginx Ingress Controller, HAProxy Ingress Controller, etc.), you might have options to configure the load balancing algorithm. You would typically configure this in the settings or configuration file of the Ingress Controller.

  1. Consider External Load Balancers: Sometimes, organizations use external load balancers like HAProxy or NGINX outside of Kubernetes/OpenShift to manage traffic. In such cases, you’d configure the load balancing algorithm within the external load balancer’s configuration.

  1. Custom Load Balancing: In some cases, you might need to implement custom load balancing logic. This could involve developing your own custom controller or middleware that runs within the Kubernetes/OpenShift cluster and handles traffic distribution according to your requirements.

  1. OpenShift Route Annotations: While OpenShift routes provide basic routing capabilities, they don’t offer direct control over load balancing algorithms. However, some Ingress Controllers might allow you to specify annotations within the route definition that could influence the behavior of the underlying load balancer.
