Another question. The quick start has you download and run the install script (which also downloads the rke2 binary) but then tells you to start the

rke2-{server|agent}.service

. But in the Installation Methods doc and all over in the other docs, it says to run the

rke2

binary with either a config file or config flags and makes no mention of starting or enabling services. What is the recommended installation method?

Please continue reading the docs. After installation you are supposed to create a configuration for every node type (all but the first node must contain the server url and the cluster token) and put it into /etc/rancher/rke2/config.yaml (or into a config.d directory at the same place). If you don't do that, you'll create a single node cluster with all default settings. After placing the config onto the node, you enable and start either rke2-server or rke2-agent service (e.g. systemctl enable --now rke2-server on a master node). Imho the documentation about how to create a config.yaml is really bad. It just explains the options, but not how to generate a yaml from it. There are pretty good video tutorials in the Rancher academy to get started.
