Tengo un proyecto que quiero dockerizar. npm install y npm build sin problemas en mi computadora, pero tiene algunos problemas cuando construyo con Docker.

Salida de la ventana acoplable:

 Sending build context to Docker daemon 56.96MB Step 1/7 : FROM node:12.2.0-alpine ---> f391dabf9dce Step 2/7 : WORKDIR /app ---> Using cache ---> b50a8efbf074 Step 3/7 : ENV PATH /app/node_modules/.bin:$PATH ---> Using cache ---> 3358967a13ab Step 4/7 : COPY package.json /app/package.json ---> Using cache ---> 851ac31a0adb Step 5/7 : RUN npm install ---> Running in 8cc36a435cec 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2.6.8 is no longer maintained.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.

Está atascado en esto aquí:

 # 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"]

He hecho esto con otros dockerfiles, pero el resultado fue el mismo.
