I think we don't want to maintain this script, if this is just a copy of the upstream script, just copy it when building the image and add of soft link to /root/usr/local/bin/immich-healthcheck

docker-immich/Dockerfile

Lines 73 to 77 in fc199ad

	echo "**** copy scripts ****" && \
	cd /tmp/immich/docker && \
	cp -r \
	scripts \
	/app/immich/server && \

I can't remember exactly why, but upstream has disabled the healtcheck by default, IMO it should be the same.

I believe it would just be best to mention a healthcheck can be added to the docker compose and probe /api/server/ping, no modifications to the container itself

Actually, I also created a modified version by copying server/bin/immich-healthcheck and then creating a symlink. Later, I figured that immich-healthcheck probably wouldn't change, so I just copied it directly for use.

I noticed in the source code (https://github.com/immich-app/immich/blob/main/server/Dockerfile) that the healthcheck is enabled by default, but in the docker-compose file (https://github.com/immich-app/immich/blob/main/docker/docker-compose.prod.yml), the healthcheck is disabled by default. That's why I thought of documenting the healthcheck in the README.

In my container immich-healthcheck is present at /app/immich/server/bin/immich-healthcheck and usable for healthcheck.
It does use IMMICH_PORT and IMMICH_HOST if set.
Unfortunately it's not working due to a lack of IMMICH_PORT (and IMMICH_HOST - but default is localhost which is fine).
IMMICH_PORT/HOST have been replaced by SERVER_PORT/HOST recently.

Maybe the easiest approach would be to set IMMICH_PORT and IMMICH_HOST as a copy of SERVER_PORT and SERVER_HOST if given?
