## @section Service
|
|
## @param services.http.enabled Enable the service.
|
|
## @param services.http.annotations Additional service annotations.
|
|
## @param services.http.externalIPs External IPs for the service.
|
|
## @param services.http.externalTrafficPolicy If `service.type` is `NodePort` or `LoadBalancer`, set this to `Local` to tell kube-proxy to only use node local endpoints for cluster external traffic. Furthermore, this enables source IP preservation.
|
|
## @param services.http.internalTrafficPolicy If `service.type` is `NodePort` or `LoadBalancer`, set this to `Local` to tell kube-proxy to only use node local endpoints for cluster internal traffic.
|
|
## @param services.http.ipFamilies IPFamilies is list of IP families (e.g. `IPv4`, `IPv6`) assigned to this service. This field is usually assigned automatically based on cluster configuration and only required for customization.
|
|
## @param services.http.labels Additional service labels.
|
|
## @param services.http.loadBalancerClass LoadBalancerClass is the class of the load balancer implementation this Service belongs to. Requires service from type `LoadBalancer`.
|
|
## @param services.http.loadBalancerIP LoadBalancer will get created with the IP specified in this field. Requires service from type `LoadBalancer`.
|
|
## @param services.http.loadBalancerSourceRanges Source range filter for LoadBalancer. Requires service from type `LoadBalancer`.
|
|
## @param services.http.port Port to forward the traffic to.
|
|
## @param services.http.sessionAffinity Supports `ClientIP` and `None`. Enable client IP based session affinity via `ClientIP`.
|
|
## @param services.http.sessionAffinityConfig Contains the configuration of the session affinity.
|
|
## @param services.http.type Kubernetes service type for the traffic.
