带有Angular的Docker-Docker构建大型图像文件

Question

I created a new project using Angular CLI and tried to set the project up with Docker.

After successfully building the image using docker build , it seems that the image size isn't normal having 1.33GB .

Also tried to ssh onto my container and it shows 499M

Here's my Docker file:

FROM node:9.5.0

ENV HOME=/usr/src/app
RUN mkdir -p $HOME
WORKDIR $HOME

COPY ./package.json $HOME
RUN npm install --quiet

COPY . $HOME

EXPOSE 80

CMD ["npm", "start"]

Is there a way to reduce the image size?

Why do I need to reduce the image size?
No particular reason. The size just doesn't seem normal for such a small project

Answer 1

Using alpine version of node decreases the size significantly.

Dockerfile : FROM node:9.5.0-alpine

Size reduced from 1.33GB down to 720MB
