I’m encountering a consistent issue with Docker builds freezing after approximately 150 seconds on an AWS EC2 instance. I have started to face this issue from today only, as till yesterday everything was perfect fine.
Quick overview of my problem:

• The Docker build process runs for about 160 seconds before freezing.
• The freeze occurs during the RUN npm run build-dev step.
• No specific error messages are displayed, and the process just hangs.

Screenshot of the process when it hangs

Below are the details of my setup.

Environment:

• Instance Type: t3.medium (2 vCPUs, 4 GiB Memory)
• OS: Ubuntu 20.04 LTS
• Docker Version: 20.10.8

Dockerfile

FROM node:lts-alpine as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install --legacy-peer-deps
COPY . .
RUN npm run build-dev

# production stage
FROM nginx:stable-alpine as production-stage
COPY --from=build-stage /app/build /var/www
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 3000
CMD ["nginx", "-g", "daemon off;"]

The command I am running to build the image:

docker build -t imagename .

What I’ve tried to resolve the issue?

• Monitored CPU and memory usage using top
• Reviewed Docker daemon logs
• Used verbose logging in Docker build
• Ensured stable network connectivity
• Every other solution I can find on stackoverflow, docker support, and in general the web.
