Docker is a platform that enables developers to package their apps into standardized containers. These containers can be deployed to lots of PaaS (like Azure, Google Cloud Platform, AWS, etc.) or even to your own servers.
This is a simple Dockerfile aimed only to be used in production. This Dockerfile will build your app, migrate your database and start your app on port 3000 (or whatever port you pass through a build argument).
FROM node:16
ARG DATABASE_URL
ARG PORT=3000
ENV DATABASE_URL ${DATABASE_URL}
WORKDIR /usr/src/app
COPY package.json yarn.lock ./
COPY db/ ./db/
RUN yarn install --frozen-lockfile
RUN yarn blitz prisma migrate deploy
COPY . /app/
RUN yarn build
EXPOSE ${PORT}
CMD yarn start -p ${PORT}Along with your Dockerfile, remember to create a .dockerignore. We
recommend to copy and paste your .gitignore.

There are some examples of Dockerfiles following good practices and
optimized for generating a small-sized image. Also, there are Dockerfiles
that can be used both in development and deployment plus some
docker-compose.yml.
