Customised, hardened Docker image for nginx

• Entire container runs as non-root user
• Logs to stdout and stderr instead of files
• Listens on port 8080 instead of privileged port 80
• Supports read-only root filesystem with /tmp as writable tmpfs
• Content served from /srv by default

Example usage

Dockerfile for static files

FROM ghcr.io/wisvch/nginx
COPY . /srv/

Dockerfile with multi-stage Node.js build

FROM node:gallium AS builder
WORKDIR /src
COPY . .
RUN yarn
RUN yarn build

FROM ghcr.io/wisvch/nginx
COPY --from=builder /src/build/ /srv/

Building and running

docker build -t nginx .
docker run --rm -it -p 127.0.0.1:8080:8080 --tmpfs /tmp --read-only nginx

then open http://127.0.0.1:8080 in your browser.
