go-zero docker-compose 搭建课件服务（四）：生成Dockerfile并在docker-compose中启动

0.1源码地址

https://github.com/liuyuede123/go-zero-courseware

1、目前的目录文件结构

目前只是创建好了courseware服务，这一章节我我们先在docker-compose跑通课件服务

└── user
    ├── api

    └── rpc

2、项目根目录下创建依赖的服务

创建etcd Dockerfile

mkdir etcd
vim etcd/Dockerfile

Dockerfile中的内容，保存并退出

FROM bitnami/etcd:latest

LABEL maintainer="liuyuede123 <liufutianoppo@163.com>"

创建etcd-manage Dockerfile

mkdir etcd-manage
vim etcd-manage/Dockerfile

Dockerfile中的内容，保存并退出

FROM evildecay/etcdkeeper

LABEL maintainer="liuyuede123 <liufutianoppo@163.com>"

3、courseware api和rpc生成Dockerfile

到courseware/api目录下生成Dockerfile

cd courseware/api
goctl docker -go courseware.go

FROM golang:alpine AS builder

LABEL stage=gobuilder

ENV CGO_ENABLED 0
ENV GOPROXY https://goproxy.cn,direct
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories

RUN apk update --no-cache && apk add --no-cache tzdata

WORKDIR /build

ADD go.mod .
ADD go.sum .
RUN go mod download
COPY . .
COPY api/etc /app/etc
RUN go build -ldflags="-s -w" -o /app/courseware api/courseware.go


FROM scratch

COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt
COPY --from=builder /usr/share/zoneinfo/Asia/Shanghai /usr/share/zoneinfo/Asia/Shanghai
ENV TZ Asia/Shanghai

WORKDIR /app
COPY --from=builder /app/courseware /app/courseware
COPY --from=builder /app/etc /app/etc

CMD ["./courseware", "-f", "etc/courseware.yaml"]

到courseware/rpc目录下生成Dockerfile

cd ../rpc
goctl docker -go courseware.go

FROM golang:alpine AS builder

LABEL stage=gobuilder

ENV CGO_ENABLED 0
ENV GOPROXY https://goproxy.cn,direct
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories

RUN apk update --no-cache && apk add --no-cache tzdata

WORKDIR /build

ADD go.mod .
ADD go.sum .
RUN go mod download
COPY . .
COPY rpc/etc /app/etc
RUN go build -ldflags="-s -w" -o /app/courseware rpc/courseware.go


FROM scratch

COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certif
