Dockerfile

FROM node:20-slim AS builder

WORKDIR /app

RUN npm install -g pnpm

COPY package.json /app/package.json
COPY pnpm-lock.yaml /app/pnpm-lock.yaml

RUN pnpm install

COPY . ./

RUN pnpm run build


FROM node:20-slim AS server

WORKDIR /app

COPY --from=builder /app/build /app/build
COPY --from=builder /app/package.json /app/package.json

RUN npm install -g pnpm
RUN pnpm install --prod --no-frozen-lockfile

EXPOSE 3000

CMD [ "HOST=0.0.0.0", "PORT=3000", "node", "build" ]

Build docker image:

docker build -t web .

Run the image:

docker run -p 3000:3000 web

production.yml

If you rather like to use docker compose to run your docker image then create production.yml file with below code.

services:
  web:
    build: .
    restart: unless-stopped
    ports:
      - 3000:3000
    command: sh -c "HOST=0.0.0.0 PORT=3000 node build"

Now run it with:

docker compose -f production.yml up --build --detach
