Ubuntu installation: network.host failure

CrateDB Installation

Hi,

I’m heading to run CrateDB on a Ubuntu machine, aiming at make it accessible via a virtual network.
When I add the network interface name in the crate.yaml file, crate fails with the following logs:
How should I approach the network values for binding and make it accessible externally? Cheers!

If you bind to a network reachable address, CrateDB performs bootstrap checks during startup
see here:

One of the bootstrap checks that fails is the one concerning heap size, which on Ubuntu should be configurable in /etc/default/crate
