But maybe I was using it wrong. However, due to technical limitations of SQLite, K3s currently does not support High Availability (HA), as in running multiple master nodes. Supports different hypervisors (VirtualBox, KVM, HyperKit, Docker, etc. Let's take for example Requesting Specific IPs subsection from documentation about request assignment from a specific pool, named in this case production-public-ips. When I ran it on docker I had to create a macvlan network for this purpose. Expand user menu Open settings menu. As you can see with your issue about 1.
