# --- web client build stage ---------------------------------------------------
|
|
# The H5 client is built here and baked into the server image, because serving it
|
|
# from the same container is what keeps the deployment to a single command: the
|
|
# reader opens http://<nas-ip>:5888 and gets the app, with no second container and
|
|
# no CORS configuration to think about.
|
|
#
|
|
# `web` is optional. When the build context has no `web` directory the copy below
|
|
# fails, so the client stage is gated behind a build arg and the runtime stage
|
|
# tolerates an absent bundle. A server-only deployment stays possible.
|
|
#
|
|
# The base image is overridable because `docker.cnb.cool` is an authenticated
|
|
# mirror: a plain `docker build` on a machine whose token has no pull rights on
|
|
# it fails at the very first stage. Docker Hub is the default; pass the mirror
|
|
# where it is reachable (CNB pipelines, or anywhere Hub is slow):
|
|
#
|
|
# docker build . -f server/Dockerfile \
|
|
# --build-arg NODE_IMAGE=docker.cnb.cool/dockerhub/node:24-alpine
