I need to know what are the hardware requirements to deploy the charmed-kubernetes charm.
I tried unsuccessfully (installation never ends) on this configuration:
hardware: notebook with Intel i7 and 32Gb RAM
VM: three kvm vm with 8 processors and 8Gb RAM
Cloud: three node LXD cluster
Controlling workstation on which juju is run
All machines have Kubuntu 18.04. LXD is version 3.12 snap installed
I used the command
juju deploy charmed-kubernetes
After 3 hours the process never ended.
After a complete restart from the hardware I end up in this situation:

And I see a countinous access to the hard disk.
In my past experience this indicates insufficient hardware to complete the installation.
So, what are the minimum hardware requirements to deploy charmed kubernetes?
