According to the docs, k3s is the latest distribution and the recommended one, when used with rancher.
However, when looking at the “create cluster options” in rancher, there is an option of which docker version to use.
Then I just read this topic:
Docker support deprecated
Rancher doesn’t care what CRI is used below a cluster when managing resources inside it. RKE2 and k3s both already use containerd.
Then I don´t understand why (as per node requerements) I should install docker on my nodes?
Obviously there is something I can not comprehend. The more docs I read, the more confused I get.
I would appreciate it if someone would tell me how to achieve:
Set up a HA cluster, with 3 master nodes(ctrl Plane - etcd - agent) - with embedded etcd -
Cluster should be setup and managed from within rancherUI,
- on nodes where docker is not installed, and never will be installed.
Happy new year!
