How to register Rancher managed Kubernetes clusters in Argo CD

Registering Rancher managed clusters in Argo CD doesn't work out of the box unless the Authorized Cluster Endpoint is used. Many users will prefer an integration of Argo CD via the central Rancher authentication proxy (which shares the network endpoint of the Rancher API/GUI). So let's find out why registering clusters via Rancher auth proxy fails and how to make it work.

Hint: If you are just looking for the solution scroll to the bottom of this page.

Why do i get an error when running argocd cluster add?

Working with ansible-vault

---

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.
