go plugins 容器构建

前边有简单介绍过go plugin 的开发，以下是关于容器集成的说明

参考代码

参考Dockerfile

FROM golang:1.15-alpine AS build-env-plugin

WORKDIR /go/src/app

ENV  GO111MODULE=on

ENV  GOPROXY=https://goproxy.cn

COPY . .

RUN set -x \

    && /bin/sed -i 's,http://dl-cdn.alpinelinux.org,https://mirrors.aliyun.com,g' /etc/apk/repositories \

    && apk update && apk add  build-base \

    && go build -buildmode=plugin -o demoapp.so app.go

​

FROM golang:1.15-alpine AS build-env

WORKDIR /go/src/app

ENV  GO111MODULE=on

ENV  GOPROXY=https://goproxy.cn

COPY . .

RUN set -x \

    && /bin/sed -i 's,http://dl-cdn.alpinelinux.org,https://mirrors.aliyun.com,g' /etc/apk/repositories \

    && apk update && apk add   build-base\

    && go build

​

FROM alpine:latest

RUN set -x \

    && /bin/sed -i 's,http://dl-cdn.alpinelinux.org,https://mirrors.aliyun.com,g' /etc/apk/repositories \

    && apk update && apk add ca-certificates && rm -rf /var/cache/apk/*

COPY --from=build-env-plugin /go/src/app/demoapp.so .

COPY --from=build-env /go/src/app/demoapp .

ENTRYPOINT [ "./demoapp" ]

构建

docker build -t dalongrong/go-plugin-demo .

运行效果

 

 

说明

以上需要使用gcc，同时使用了alpine 作为容器镜像，所以直接安装 build-base 就可以，同时使用了多阶段构建
同时需要注意golang 版本的一直
