I am trying to install an agent and get the error... [ERROR] Only https:// URLs are supported for K3S_URL. When the server/master is installed is SSL auto provisioned?

https://docs.k3s.io/quick-start#install-script

To install on worker nodes and add them to the cluster, run the installation script with the

K3S_URL

and

K3S_TOKEN

environment variables. Here is an example showing how to join a worker node:

curl -sfL <https://get.k3s.io> | K3S_URL=<https://myserver:6443> K3S_TOKEN=mynodetoken sh -

note that this is a https URL, not http

So does the server expose itself on HTTPS?

you don’t need to do that yourself, the Kubernetes cluster generates its own root CAs on startup.

I LL test. Thank you

Was there something you saw in the docs that made you think you had to set up SSL for the cluster manually?

I was actually thinking why should I specify the protocol if the script just accepts HTTPS. And given the error message also wondering if I had to indeed provision one or configure it somehow

that’s just how it works, it wants a URL not a host:port
