Docker compose npm install took hours - amazon-web-services

Question

I am using aws ec2 free tier for Ubuntu 20.04. I am deploying nginx, Jenkins, Nest.js application using docker, but while building Nest.js, npm install glob rimraf took literally HOURS. Is it because of AWS free tier which is too small? When I monitored CPU usage from ec2 console, it is almost 100%. However, glob and rimraf is not a huge package. They are only 56kb and 70kb... but downloading images like node is really fast.
Is there any way to speed up this process?
Here is my dockerFile and docker-compose.yaml
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install glob rimraf
RUN npm install --only=development
COPY . .
RUN npm run build
FROM node:12.19.0-alpine3.9 as production
ARG NODE_ENV=production
ENV NODE_ENV=${NODE_ENV}
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install --only=production
COPY . .
COPY --from=development /usr/src/app/dist ./dist
CMD ["node", "dist/main"]
