本文由go語言教學專欄為大家介紹Kubernetes中的gRPC負載平衡 ,希望對需要的朋友有幫助!
下載安裝Docker Desktop ,並啟動內建的Kubernetes 叢集。
# 安装 Gobrew install go# 安装 Protobufbrew install protobuf# 安装 Istiobrew install istioctl kubectl config use-context docker-desktop istioctl install -y
github.com/jxlwqq/grpc-lb
拉取程式碼:
git clone git@github.com:jxlwqq/grpc-lb.gitcd grpc-lb
指令 | 說明 |
---|---|
##make init
| 安裝protoc-gen-go 和protoc-gen-grpc|
make protoc
| 基於proto文件,產生*_pb.go 和*_grpc.pb.go|
#make docker-build
| 建構docker 映像|
make kube-deploy
| 在叢集中部署服務|
make kube-delete
| #刪除服務|
make istio-inject
| #注入Istio 邊車
make docker-build # 构建镜像(构建好的镜像,不 push 到远程仓库中)
docker images ls
