Recently I made the design for k8s registry: ## Objective add one new registry for DS, and make it free of zookeeper dependency on k8s environments. this registry should only be used when DS running on k8s ## Core Implementations dependency: https://github.com/fabric8io/kubernetes-client distributed lock: [fabric lock](https://github.com/fabric8io/kubernetes-client/tree/master/kubernetes-client/src/main/java/io/fabric8/kubernetes/client/extended/leaderelection/resourcelock ) <table> <tr> <td> item <td>zookeeper registry <td>k8s registry <tr> <td> how to register self <td> create one new node certain path <td> do nothing, pods on ks8 environments will be discovered automatically <tr> <td> how to discover otherss <td> use CuratorFramework client to connect and watch zk cluster <td> use fabric client to connect and watch k8s cluster <tr> <td> how to implements distributed lock <td> InterProcessMutex in curator project <td> lock in fabric, according to [stack overflow](https://stackoverflow.com/questions/34409160/kubernetes-getting-cluster-locks-over-a-replication ) <tr> <td> how to implements HeartBeatTask <td> periodically persist ephemeral node on specific zk path <td> do nothing, K8s will check pod`s liveness automatically </table> -- This is an automated message from the Apache Git Service.
