打包 docker 镜像过大

[k631583871]

我尝试直接使用源码的方式打包成docker镜像，打包之后超过 300M， 使用很不方便。 能否提供一个打包成二进制的命令，支持生成更小的镜像，方便大家在服务器上部署

我添加了一个dockerfile，你可以试试用它来打包，打出来的镜像100多M

我尝试了dockerfile. 打包了 113MB, 这个大小还可以.

我觉得给dockerfile里面可以添加下面的内容

EXPOSE 9527
ENV PORT 9527
ENV BIND_IP '127.0.0.1'
ENV CONNECT_PWD ''
ENV CONFIG_PATH 'config.js'
ENV LOG_PATH '/server/logs'
ENV DATA_PATH '/server/data'

添加后的样子

FROM node:16-alpine AS builder
WORKDIR /server
COPY . .
# RUN npm install
RUN npm ci
RUN npm run build

FROM node:16-alpine AS final
WORKDIR /server
EXPOSE 9527
ENV PORT 9527
ENV BIND_IP '127.0.0.1'
ENV CONNECT_PWD ''
ENV CONFIG_PATH 'config.js'
ENV LOG_PATH '/server/logs'
ENV DATA_PATH '/server/data'
COPY --from=builder ./server/server ./server
COPY package.json package-lock.json config.js index.js ./
RUN npm ci --omit=dev

CMD [ "npm", "start" ]
