Install sqlite3 dependencies. You can skip this if you don’t use sqlite3 in the image,
in which case you should also move better-sqlite3 to “devDependencies” in package.json.
RUN --mount=type=cache,target=/var/cache/apt,sharing=locked
–mount=type=cache,target=/var/lib/apt,sharing=locked
apt-get update &&
apt-get install -y --no-install-recommends libsqlite3-dev python3 build-essential &&
yarn config set python /usr/bin/python3
From here on we use the least-privileged node user to run the backend.
USER node
This should create the app dir as node.
If it is instead created as root then the tar command below will fail: can't create directory 'packages/': Permission denied.
If this occurs, then ensure BuildKit is enabled (DOCKER_BUILDKIT=1) so the app dir is correctly created as node.
WORKDIR /app
This switches many Node.js dependencies to production mode.
ENV NODE_ENV production
Copy repo skeleton first, to avoid unnecessary docker cache invalidation.
The skeleton contains the package.json of each package in the monorepo,
and along with yarn.lock and the root package.json, that’s enough to run yarn install.
COPY --chown=node:node yarn.lock package.json packages/backend/dist/skeleton.tar.gz ./
RUN tar xzf skeleton.tar.gz && rm skeleton.tar.gz
RUN --mount=type=cache,target=/home/node/.cache/yarn,sharing=locked,uid=1000,gid=1000
yarn install --frozen-lockfile --production --network-timeout 300000
Then copy the rest of the backend bundle, along with any other files we might want.
COPY --chown=node:node packages/backend/dist/bundle.tar.gz app-config*.yaml ./
RUN tar xzf bundle.tar.gz && rm bundle.tar.gz
CMD [“node”, “packages/backend”, “–config”, “app-config.yaml”]
