How to register Rancher managed Kubernetes clusters in Argo CD

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?

Service Account tokens and the Rancher authentication proxy

kubectl multi-version brews

Applicability

The instructions below apply to older versions of Homebrew which still provide switch capability.

For current Homebrew, you'll likely need to keep Versions around, and build locally. Here's my versions repository https://github.com/rdump/homebrew-versions

MacPorts is now keeping versioned installations available as well, by default.

Deploying Kubernetes 1.11 on DigitalOcean with Rancher 2.0

Deploying Kubernetes 1.11 on DigitalOcean with Rancher 2.0

This guide will help you add support for DigitalOcean volumes and load balancers to a freshly deployed Kubernetes 1.11 cluster. It assumes you already have a cluster deployed through Rancher, have kubectl set up, and helm installed.

Set up helm

  • kubectl apply -f helm-rbac.yaml
  • helm init --service-account tiller

helm-rbac.yaml:




  


  




    


          
    

      

        
        

          

              @robv8r
          

          

            
                robv8r
                / docker_tags.sh
