How-To: From single node to multi-node cratedb clusters

from a cab interview:

Setting CrateDB up locally
Where customers would encounter problems as well, is setting up CrateDB outside of the Cloud. While the Cloud "obviously does everything that you want it to do", it's really hard to do a setup of CrateDB outside of the Cloud and run it locally.

For example, there is no easy way from a single-node installation to a multi-node installation, a setup, with which many people start when using CrateDB, Walter assumes.

Once you start it up on the first node, Crate says: I’m alone in this world and no one ever gonna join my tribe.

It is hard to go from one node to a multi-node setup.
