If we are using rancher/rancher:stable as server?
how can we pull stable rancher agent in AGENTCOMMAND?

rancher/rancher-agent is coupled with rancher/rancher and will be automatically filled in in the generated AGENTCOMMAND.

Hi superseb! First of all, thank you for this work.

Did you get some documentation about Rancher 2.x API? Because I'm looking for it since long, and haven't found a thing yet.

I'm trying to use this script, but the server name never get filled in rancher. The curl for "Set server-url" don't fails, and in the output show the stuff seemingly right, but the value seems to set empty, and, for example, when trying to get nodeCommand, the parameter for "--server" is empty.

Do you have any idea why this problem could be happening?

Very best regards.

I think in Generate nodecommand section query param is clusterId not id
