我应该将`package-lock.json`复制到Dockerfile中的容器映像吗？

这是我的Dockerfile：

FROM node:12-slim

ENV NODE_ENV=production

WORKDIR /

# COPY . . # COPY ENTIRE FOLDER ?

COPY ./package.json ./package.json
COPY ./dist ./dist

RUN npm install --only=production

EXPOSE 8080

ENTRYPOINT npm start

这是我的.dockerignore文件：

node_modules

你看我只是在复制package.json而不是package-lock.json. 我猜想，因为我将运行RUN npm install构建图像，我认为它应该创建自己的package-lock.json.

但是我在构建过程中收到了这个警告：

那么，我应该将它添加到我的Dockerfile?

COPY ./package-lock.json ./package-lock.json

回答

COPY package.json package-lock.json .
# Run `npm ci` _before_ copying the application in
RUN NODE_ENV=production npm ci
# If any file in `dist` changes, this will stop Docker layer caching
COPY ./dist ./dist
