Monorepo and Microservices kit using micro/micro for @kzmake

• クリーンアーキテクチャ(を意識したレイヤードアーキテクチャ)
• マイクロサービス
• モノレポ
• 軽量DDD

• Inspired by @xmlking’s micro-starter-kit
• Inspired by @kgrzybek’s modular-monolith-with-ddd

Roadmap

• Monorepo
• Microservices with micro/go-micro
• gRPC microservices
• Support HTTP-API
• Support CLI
• Support NATS
• Kubernetes with Kustomize
• Input Validation with PGV
• Linting Protos with Buf
• Observability
• Building/Testing with Bazel
• Support gRPC reflection API

Getting Started

Init

git clone https://github.com/kzmake/micro-kit.git $GOPATH/src/github.com/kzmake/micro-kit
cd $GOPATH/src/github.com/kzmake/micro-kit
go mod download

Service Discovery

# install
go get -v go.etcd.io/etcd
# or
brew install etcd
# run
etcd
# or
brew servces start etcd

Client

# install
go get -u github.com/micro/micro/v2
# run
micro --version

Run

# grpc
go run service/task/cmd/srv/main.go service/task/cmd/srv/plugin.go --registry=etcd --server_address=localhost:3001
# api
go run service/task/cmd/api/main.go --registry=etcd --server_address=localhost:3000
