I’m using DigitalOcean’s Kubernetes and installed 1-click apps Nginx ingress controller. I changed the algorithm of the load balancer to Least Connections. It works but every time the auto scale adds or removes nodes, the load balancer will set the algorithm back to Round Robin. How can I change the load balancer’s algorithm permanently?

Hello @trungld ,

I believe you are setting the LoadBalancer(LB) algorithm from the cloud panel.

All LoadBalancers(LB) provisioned by Kubernetes are managed by the Cloud Controller Manager(CCM) running on the master. Any manual modifications to the LB through the cloud panel will be overwritten by the CCM during its reconciliation process to ensure the LB is configured properly with the state defined by the Kubernetes service.

In order to configure your LB you need to use Kubernetes service annotations. For information on how to apply annotations, you can use the command:

kubectl annotate --help

Docs for DO service annotations can be found here:


Service annotations can also be found on our public GitHub repository:


To set the LB algorithm can you please try adding the below annotation to your LB.

service.beta.kubernetes.io/do-loadbalancer-algorithm: "least_connections"

Please find the below link for your reference:


Hope that this helps!

Best Regards, Chandan Sagar Pradhan
