Solution: Containerize a static site using Docker

1. Create a .dockerignore file at the root of the project directory. Add the following content to the file:

node_modules
dist
README.md

2. Create a Dockerfile at the root of the project directory with the following content:

FROM node:22-alpine
RUN addgroup --system lightness && adduser --system lightness --ingroup lightness
WORKDIR /lightness
COPY . .
RUN chown -R lightness:lightness .
USER lightness
RUN npm ci
CMD npm start

3. Build the image and run a container. The following commands assume you are at the root of the project directory.

$> docker build -t lightness .
$> docker run -p 8080:5173 lightness
