I've found out-of-the-box distributed erlang difficult to run in environments with a lot of instance churn (e.g. containerized deployments on Kubernetes), so much so that I generally opt to not connect my nodes for erlang message passing. Does anyone here have experience running Lasp in Kubernetes? Is Lasp effective in monitoring and adjusting to new or dead nodes?

Lasp use Partisan for its distribution, not the default erlang distribution.

It was built exactly to deal with a high level of churn, specifically for edge computing with spotty network. So yes it does.
