1. Docker部署

Micro易于在docker容器中运行

1.1. 预置的镜像

Docker Hub上提供了预置的镜像

1.2. 安装Micro

docker pull microhq/micro

1.3. Compose

使用docker compose运行本地部署

consul:
  command: -server -bootstrap -rejoin 
  image: progrium/consul:latest
  hostname: "registry"
  ports:
  - "8300:8300"
  - "8400:8400"
  - "8500:8500"
  - "8600:53/udp"
api:
  command: --registry_address=registry:8500 --register_interval=5 --register_ttl=10 api
  build: .
  links:
  - consul
  ports:
  - "8080:8080"
sidecar:
  command: --registry_address=registry:8500 --register_interval=5 --register_ttl=10 sidecar
  build: .
  links:
  - consul
  ports:
  - "8081:8081"
web:
  command: --registry_address=registry:8500 --register_interval=5 --register_ttl=10 web
  build: .
  links:
  - consul
  ports:
  - "8082:8082"

1.4. 从头开始构建

Dockerfile包含在仓库中。

FROM alpine:3.2
RUN apk add --update ca-certificates && \
    rm -rf /var/cache/apk/* /tmp/*
ADD micro /micro
WORKDIR /
ENTRYPOINT [ "/micro" ]

1.4.1. 构建二进制

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w' -i -o micro ./main.go

1.4.2. 构建镜像

docker build -t micro .
