Flink 1.12

[Boris Lublinsky]

It is great that Flink 1.12 is out. Several questions:

1. Is official Flink 1.12 distribution https://flink.apache.org/downloads.html 
<https://flink.apache.org/downloads.html> specifies Scala versions, but not 
Java versions. Is it Java 8?
2. I do not see any 1.12 docker images here https://hub.docker.com/_/flink 
<https://hub.docker.com/_/flink>. Are they somewhere else?
3 Flink 1.12 introduces Kubernetes HA support 
https://ci.apache.org/projects/flink/flink-docs-stable/deployment/ha/kubernetes_ha.html
 
<https://ci.apache.org/projects/flink/flink-docs-stable/deployment/ha/kubernetes_ha.html>,
 but Flink native Kubernetes support 
https://ci.apache.org/projects/flink/flink-docs-release-1.12/deployment/resource-providers/native_kubernetes.html
 
<https://ci.apache.org/projects/flink/flink-docs-release-1.12/deployment/resource-providers/native_kubernetes.html>
 has no mentioning of HA. Are the 2 integrated? DO you have any examples of 
starting HA cluster using Flink native Kubernetes?
