= LoadBalancer for Kubernetes
|
|
|
|
This project includes Spring Cloud Load Balancer for load balancing based on Kubernetes Endpoints and provides implementation of load balancer based on Kubernetes Service.
|
|
To include it to your project add the following dependency.
|
|
Fabric8 Implementation
|
|
[source,xml]
|
|
----
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|

<artifactId>spring-cloud-starter-kubernetes-fabric8-loadbalancer</artifactId>

Kubernetes Java Client Implementation
|
|
[source,xml]
|

|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-starter-kubernetes-client-loadbalancer</artifactId>
|
|
</dependency>
|
|

|
|
|
|
To enable load balancing based on Kubernetes Service name use the following property. Then load balancer would try to call application using address, for example `service-a.default.svc.cluster.local`
|
|
[source]
|
|
----
|
|
spring.cloud.kubernetes.loadbalancer.mode=SERVICE
|
|
----
|
|
|
|
To enabled load balancing across all namespaces use the following property. Property from `spring-cloud-kubernetes-discovery` module is respected.
|
|
[source]
|
|
----
|
|
spring.cloud.kubernetes.discovery.all-namespaces=true
|
|
----
|
|
|
|
If a service needs to be accessed over HTTPS you need to add a label or annotation to your service definition with the name `secured` and the value `true` and the load balancer will then use HTTPS to make requests to the service.
