1. golang程序常见docker

直接运行

#设置基础镜像来源
    FROM golang:1.17-alpine
    #设置时区 
    ENV TZ=Asia/Shanghai
    RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
    #设置代理
    RUN go env -w GOPROXY=https://goproxy.cn,direct
    #设置工作目录
    WORKDIR /data/
    #复制代码
    COPY data/. .
    #安装环境组件
    RUN go mod tidy  -compat=1.17
    #启动主程序
    #RUN go run main.go
    #设置端口
    EXPOSE 8080
    #设置启动命令
    CMD ["go","run","main.go"]

构建二进制运行

# 构建成二进制文件
        FROM golang:1.17-alpine
        # 开启 Go Module
        RUN go env -w GO111MODULE=on
        RUN go env -w GOPROXY=https://goproxy.cn,direct
        
        WORKDIR /data/
        COPY . .
        RUN CGO_ENABLED=0 GOOS=linux go build -a -o app.api .
        
        # 配置运行环境
        FROM alpine:3
        # 设置为中国时区
        # 设置系统根证书
        RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
        RUN apk --no-cache add tzdata && \
            apk add ca-certificates && \
            cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
            echo "Asia/Shanghai" > /etc/timezone
        ENV TZ Asia/Shanghai
        WORKDIR /data/
        COPY --from=0 /data/app.api .
        ## 本地测试用，直接用当前的yaml文件
        COPY --from=0 /data/conf.yaml .
        CMD ["./app.api"]
