# build-cdn.sh — one production build of the pulled commit into /data/cdn, one at a time.
|
|
# snapshot (so the pull loop can't change files mid-build) -> apply the public exclusions ->
|
|
# the build steps WITHOUT the gates (memory-capped) -> check the output -> the exclusion check again
|
|
# (refuses the swap) -> atomic swap of /data/cdn/current.
|
|
# No gates here: they already passed before the commit reached main, and a full gate run on a
|
|
# 2-vCPU container takes most of an hour. The public exclusions are NOT a gate and always run.

# Exit 75 = another build holds the lock. To stop a build, kill the PID in /tmp/build-cdn.pid
|
|
# (never a process group: inside a container the group can be PID 1, i.e. the whole container).
