Provide static IP-address for LoadBalancer

Description

We allow users to expose database clusters and its components through various Service Types, including load balancers.

There is a use case, where user wants to have a static IP-address for the load balancer. This also includes internal load balancers in the clouds.

 

This can be done through `loadBalancerIP` field.

spec:   loadBalancerIP: 1.2.3.4   type: LoadBalancer

  • We are going to pass through loadBalancerIP parameter to the service spec.

  • If exposeType is not LoadBalancer, we still pass through loadBalancerIP parameter to the spec

  • We rely on Kubernetes logic to parse and make a decision about loadBalancerIP valid inputs

    • We return the error if service creation fails

  • We are not adding loadBalancerIP to PXC exposure, as PXC is exposed as a service per Pod fashion (so IP cannot be the same for all nodes).

  • We are going to introduce loadBalancerIP into the custom resource in the following places:

spec: pxc: expose: type: LoadBalancer proxysql: loadBalancerIP: 1.2.3.4 haproxy: loadBalancerIP: 1.2.3.4
