Basic Dockerfile for a Node App

· One min read

This is a simple Dockerfile that builds a full stack Javascript project.

FROM node:14-alpine

EXPOSE 8080

RUN mkdir -p /home/node/app && chown -R node:node /home/node/app

WORKDIR /home/node/app

COPY --chown=node:node . .

USER node

RUN cd /home/node/app/client && npm ci && npm run build
RUN cd /home/node/app/server && npm ci && npm run build

WORKDIR /home/node/app/server

CMD ["npm", "start"]

To start the container and expose a .env file:

docker run --name app-name \
    -p 8080:8080 \
    -v /absolute/path/to/.env:/home/node/app/server/.env \
    --restart unless-stopped -d image-name
