How to upgrade rancherd 2.5.17 to newest ver

Hello,

I installed ranched with command curl -sfL https://get.rancher.io | sh - and its running as daemon.

My version is VERSION: v2.5.17 (HEAD) after trying to add clusters to my rancher some of them have to new version to be accepted by manger. All my clusters with 1.20.15 are fine but 1.24+ are stuck on pending. Can anyone tall me how in easy way I can upgrade my 2.5.17 to new 2.8.1 Im stuck as hell trying this for 2h now…

Hi,

RancherD has been discontinued, so you cannot upgrade it as a binary. However, RancherD bootstraps an RKE2 cluster with Rancher on top of it. So, you can still interact with the RKE2 cluster as normal.

The v1.24.X clusters are not working because Rancher is too old. You need to upgrade the Rancher on RKE2, without trying to use RancherD. Please follow the standard procedure as described here: Upgrades | Rancher.

Basically, you need a way to connect to RKE2 (on the node itself, one can be used at /etc/rancher/rke2/rke2.yaml), and you need helm from here : https://helm.sh/docs/intro/install/#from-script.

  • Then, you will need to tell helm where to find the kubeconfig file. On the rancherd node, that will be:
chmod 666 /etc/rancher/rke2/rke2.yaml
export KUBECONFIG=/etc/rancher/rke2/rke2.yaml

(this is not super secure, you might want to copy the file to some other place and leave it with restricted permissions, but that’s for another post).

  • Check the helm repo
helm repo list
helm repo add rancher-stable https://releases.rancher.com/server-charts/stable
  • get the older Rancher Helm values with
helm get values rancher -n cattle-system
  • Upgrade Rancher while setting the right values using helm upgrade ... .

Then, you should be able to upgrade your clusters. Please check at each time, the Rancher Support Matrix.
