使用 Zookeeper 作为注册中心

This example shows dubbo-go’s service discovery feature with Zookeeper as registry.

使用方式

通过以下方式指定注册中心地址：

ins, _ := dubbo.NewInstance(
	dubbo.WithName("dubbo_registry_nacos_server"),
	dubbo.WithRegistry(
		registry.WithZookeeper(),
		registry.WithAddress("127.0.0.1:2181"),
	),
	dubbo.WithProtocol(
		protocol.WithTriple(),
		protocol.WithPort(20000),
	),
)

srv, err := ins.NewServer()

How to run

Start Zookeeper server

This example relies on zookeeper as registry, follow the steps below to start a zookeeper server first.

Start zookeeper with docker, run docker run --rm -p 2181:2181 zookeeper or make -f $DUBBO_GO_SAMPLES_ROOT_PATH/build/Makefile docker-up.
Download and start zookeeper locally on your machine.

Run server

$ go run ./go-server/cmd/server.go

test rpc server work as expected:

$ curl \
    --header "Content-Type: application/json" \
    --data '{"name": "Dubbo"}' \
    http://localhost:20000/greet.GreetService/Greet

check url address successfully registered into zookeeper:

# enter zookeeper bin directory, for example '$HOST_PATH/apache-zookeeper-3.5.9-bin/bin'
$ ./zkCli.sh
[zk: localhost:2181(CONNECTED) 0] ls /services/dubbo_registry_zookeeper_server
[30.221.147.198:20000]

Run client

$ go run ./go-client/cmd/client.go
hello world
