    --volume=/tmp/etcd-data.tmp:/etcd-data \
    --restart=always \
    quay.io/coreos/etcd \
    /usr/local/bin/etcd \
    --name etcd0 \

    --listen-peer-urls http://0.0.0.0:2380 \
    --initial-advertise-peer-urls http://0.0.0.0:2380 \

    --initial-cluster-token tkn

Run nsq

$ 
1.下载nsq docker镜像
    docker pull nsqio/nsq 
2.启动nsqlookupd
    docker run -d --link nsqd --name lookupd -p 4160:4160 -p 4161:4161 --restart=always nsqio/nsq /nsqlookupd  
3.启动nsqd
    docker run -d --link lookupd --name nsqd -p 4150:4150 -p 4151:4151 --restart=always nsqio/nsq /nsqd --lookupd-tcp-address=lookupd:4160
4.启动nsqadmin
    docker run -d --link lookupd --link nsqd --name nsqadmin -p 4171:4171 --restart=always nsqio/nsq /nsqadmin --lookupd-http-address=lookupd:4161

Run Service

$ go run main.go --registry=etcd --broker=nsq

Building a container

If you would like to build the docker container do the following

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w' -i

run in docker

docker run --link etcd --link nsqd -p 50051:50051 --name=goods -e MICRO_SERVER_ADDRESS=:50051 -e MICRO_REGISTRY=etcd -e MICRO_REGISTRY_ADDRESS=http://etcd:2379 -e MICRO_BROKER=nsq -e MICRO_BROKER_ADDRESS=nsqd:4150  udian/goods

Run the micro api

启动api服务，并转发到rpc服务

micro --registry=etcd  api --handler=rpc

Or via Docker

docker run --link=etcd -p 8080:8080 -e MICRO_REGISTRY=etcd -e MICRO_REGISTRY_ADDRESS=http://etcd:2379 ttouch/micro api --handle=rpc

api调用

curl -H 'Content-Type: application/json' -d '{"name": "John2","barcoe":"2222"}' http://127.0.0.1:8080/v1/goods/detail
