gRPC Kit

主要基于以下几个核心类库实现：

• grpc
• grpc-gateway

简要概述

快速生成微服务模版，为同一产品提供统一的治理方式，提高多人协作效率

生成代码并运行（本机方式）

创建应用模版

mkdir -p $GOPATH/src/github.com/opsaid
cd $GOPATH/src/github.com/opsaid

grpc-kit-cli new -t service -p opsaid -s test1

下载依赖的环境

make protoc
make protoc-gen-go
make protoc-gen-go-grpc
make protoc-gen-grpc-gateway
make protoc-gen-openapiv2

运行应用代码

make run

生成代码并运行（容器方式）

创建应用模版

docker run \
    --rm \
    -v $(pwd):/usr/local/src \
    -w /usr/local/src \
    ccr.ccs.tencentyun.com/grpc-kit/cli:0.3.5 \
    grpc-kit-cli new -t service -p opsaid -s test1

运行应用代码

docker run -i -t --rm \
    -v $GOPATH/pkg:/go/pkg \
    -v $(pwd):/usr/local/src \
    -w /usr/local/src \
    --network host \
    ccr.ccs.tencentyun.com/grpc-kit/cli:0.3.5 \
    make run

• 微服务性能数据

# curl http://127.0.0.1:8080/metrics

# HELP go_gc_duration_seconds A summary of the pause duration of garbage collection cycles.
# TYPE go_gc_duration_seconds summary
go_gc_duration_seconds{quantile="0"} 0.000114581

go_gc_duration_seconds_sum 0.033207328
go_gc_duration_seconds_count 12
# HELP go_goroutines Number of goroutines that currently exist.
# TYPE go_goroutines gauge
go_goroutines 19

• 微服务健康探测

探测流量仅到 gateway 不会调度到 grpc 服务。

# curl http://127.0.0.1:8080/ping
OK

探测流量同时到 gateway 与 grpc 服务。

# curl 'http://127.0.0.1:8080/api/healthz?service=test1.v1.opsaid'
{"status":"SERVING"}
