- 使用这种方式对nest打包，结果是
FROM alpine:latest as build-stage
RUN apk add --no-cache --update nodejs npm yarn
WORKDIR /temp
COPY dist ./dist
COPY prisma ./prisma
COPY package.json .
COPY tsconfig.json .
COPY nest-cli.json .
COPY tsconfig.build.json .
COPY .env .
RUN yarn --registry https://registry.npmmirror.com/
CMD ["sh", "-c", "node dist/src/main.js"]
- 优化
FROM alpine:latest as development
RUN apk add --no-cache --update nodejs npm yarn
WORKDIR /usr/src/app
COPY --chown=node:node package*.json ./
COPY prisma ./prisma
COPY tsconfig.json .
COPY nest-cli.json .
COPY tsconfig.build.json .
COPY .env .
RUN npm ci
COPY --chown=node:node . .
USER node
FROM node:18-alpine As build
WORKDIR /usr/src/app
COPY --chown=node:node package*.json ./
COPY --chown=node:node --from=development /usr/src/app/node_modules ./node_modules
COPY --chown=node:node --from=development /usr/src/app/prisma ./prisma
COPY --chown=node:node --from=development /usr/src/app/package*.json ./
COPY --chown=node:node --from=development /usr/src/app/tsconfig*.json ./
COPY --chown=node:node --from=development /usr/src/app/nest-cli.json ./
COPY --chown=node:node . .
RUN npm run build
ENV NODE_ENV production
RUN npm ci --only=production && npm cache clean --force
USER node
FROM alpine:latest as production
RUN apk add --no-cache --update nodejs npm yarn
COPY --chown=node:node --from=build /usr/src/app/node_modules ./node_modules

COPY --chown=node:node --from=build /usr/src/app/nest-cli.json ./
COPY --chown=node:node --from=build /usr/src/app/.env .
CMD [ "node", "dist/src/main.js" ]
打包结果
运行结果
-减少了300M左右
