# The homeserver URL and server_name differ per environment, and config.json is
|
|
# read by the browser rather than the build, so baking it into the image would
|
|
# mean one image per environment. Dropped into /docker-entrypoint.d, which the
|
|
# upstream nginx entrypoint runs (in lexical order) before starting nginx —
|
|
# no ENTRYPOINT override, so the image's own startup work still happens.
