Kvrocks Cluster Controller

Controller for the Kvrocks cluster has the following key features:

• Failover - controller will failover or remove the master/slave node when probing failed
• Scale out the cluster in one line command
• Manage many clusters in one controller cluster
• Support multi metadata storages like etcd and so on

Build and Running

Requirements

• Go >= 1.16

Build binaries

$ git clone https://github.com/KvrocksLabs/kvrocks_controller
$ cd kvrocks_controller
$ make # You can find the binary file in the `_build` dir if all goes good

1. Run the controller server

# Use docker-compose to setup the etcd
$ make setup
# Run the controller server
$ ./_build/kvrocks-controller-server -c config/config.yaml

2. Use the controller client to interactive with the server

# Create the namespace `test-ns` 
$ create namespace --namespace test-ns
# Create the cluster `test-cluster` with nodes 127.0.0.1:6666 and 127.0.0.1:6667 
$ create cluster --namespace test-ns --cluster test-cluster --nodes 127.0.0.1:6666,127.0.0.1:6667
# List shard in cluster `test-cluster`
$ list shard --namespace test-ns --cluster test-cluster
