Recommended specs for VMs running docker-valhalla

[isakengstrom]

Previously (up to 3.3.0) I've had the container running on a VM with 1 cpu core and 1.5GB of memory, but with the latest release, this does not seem to be enough. Attempts result in 3x startup time (around 1.5 hours), followed by a crash when the container is about to finish the startup. Increasing the VM's capacity to 2 cores and 3GB of memory seem to fix this issue. Are there any recommended minimum spec requirements?

It’s not that easy to determine minimum specs for building tiles. Just gotta trial & error if you’re on modest hardware.

Note that the runtime for the service requires much less memory.
