I checked the official documentation, which only mentioned clusters, I wonder if a single node supports ILM?  
According to my understanding, a single-node ES has all node roles and all data tiers, so it should support ILM?

Yes, you can use ILM on a single-node cluster, but some actions won't do anything, like move shards to another data tier for example.

But everything else, like rollover, reducing shards, shrinking indices, deleting etc works as expected.
