Should probably have a note that these variables need to be set to the same value across the cluster (much like NODE_ID needs to be unique)

We don't have any support for kubernetes or swarm yet with the current implementation but if you mean that /data/.env should be used in the main container and sidecar ones as well, this is already the case as we mount the same volume across the compose stack:

docker/examples/compose/compose.yml

Lines 52 to 53 in 846881f

	volumes:
	- "./librenms:/data"

docker/examples/compose/compose.yml

Lines 77 to 78 in 846881f

	volumes:
	- "./librenms:/data"

docker/examples/compose/compose.yml

Lines 111 to 112 in 846881f

	volumes:
	- "./librenms:/data"

...

If .env is shared across containers, how can NODE_ID be unique if it is set there?

Oh I guess you mean for the dispatcher container? In this case I think we should provide a NODE_ID env var that would override the one from /data/.env. WDYT?
