Hallo,
I m testing the new 2.3 version.
The problem_
0/3 nodes are available: 3 node(s) had taints that the pod didn’t tolerate.
while trying to install a windows image from docker-hub.
Has anyone hints what is going wrong? I selecet all options to define a windows cluster.

Thanks for hints
Ralf

What steps from https://rancher.com/docs/rancher/v2.x/en/cluster-provisioning/rke-clusters/windows-clusters/ did you follow and what actually are you executing? We taint Linux workers by default but 3 nodes that do not tolerate doesn’t sound correct if you followed the docs.

Hallo,
my fault. Made a mistake and tried to connect to a linux host.
Now I made asetup with a fresh Windows2019 Server as node again but this ends with the message in the last line.

Found in the infos for the preview release a hint that EE is needed but there is no information for the final version.

Do you ve an hint for me?

This is not documented clearly, I added a comment to this issue to get the docs fixed: https://github.com/rancher/docs/issues/1767

TL;DR: it needs Docker Enterprise as Community was tested and won’t work. That’s why the agent fails when Enterprise is not found.

Hallo,
thanks for the informations.
Bad news for me.
Will there be a solution in one of the next versions or is this feature blocked by docker?
