I have explicitly set these annotations on the Service in kubernetes.
service.beta.kubernetes.io/do-loadbalancer-healthcheck-port: "80"
service.beta.kubernetes.io/do-loadbalancer-healthcheck-protocol: tcp
service.beta.kubernetes.io/do-loadbalancer-protocol: tcp
service.beta.kubernetes.io/do-loadbalancer-type: REGIONAL_NETWORK
However, the load balancer ends up configured with this healtcheck: "http://0.0.0.0:10256/healthz"
Using
digitalocean-cloud-controller-manager v0.1.64
