I have a project that I want to dockerize. I run npm install and npm build with no problem on my computer, but it has some problems when I build with Docker.

Docker output:

Sending build context to Docker daemon  56.96MB

npm WARN deprecated core-js@1.2.7: core-js@<2.6.8 is no longer maintained. Please, upgrade to core-js@3 or at least to actual version of core-js@2.

It is stuck in this here:

Dockerfile:

# base image
FROM node:12.2.0-alpine

# set working directory
WORKDIR /app

# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH

# install and cache app dependencies
COPY package.json /app/package.json
RUN npm install
RUN npm install react-scripts@3.0.1 -g --silent

# start app
CMD ["npm", "start"]

I have done this with other dockerfiles, but the result was the same.
