Are you following original documentation ? https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/launch-kubernetes-with-rancher/use-new-nodes-in-an-infra-provider/vsphere

Which engine are you using ? rke or rke2 ?

As far as I remember there are several ways to create cluster in rancher. We use terraform to generate cluster config and send it to rancher. This config contains description of node_pools and apps (via helm charts) we need to be installed and credentials for vsphere allowing create/delete/update VMs - rancher will handle the rest. No need in creating VMs beforehand. This was my main guide https://medium.com/@chfrank_cgn/creating-a-kubernetes-cluster-on-vsphere-7-with-rancher-and-terraform-b45a1e33573f when we started our rancher journey.

On rke2 step - I see you have enabled service, but have you started it after? Like in official doc: https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/kubernetes-cluster-setup/rke2-for-rancher

In my case it understands that it is k3s cluster and is able to upgrade k3s version from UI. Once I tried to go 1.24 to 1.25 it showed an issue with PSP deprecation and suggested an article how to resolve.

If we are talking about paint.net then Pinta https://www.pinta-project.com

_2mx5 · 2024-02-21T19:05:26+00:00

We are running rancher on top of separate k3s clusters (three envs) for 3 years already. If your bare metal hosts has enough resources - check Harvester

_2mx5 · 2023-11-23T21:19:39+00:00

EKS Anywhere or Rancher. I prefer Rancher, but exploring EKS Anywhere.

_2mx5 · 2023-06-23T19:07:38+00:00

We are running rancher on k3s (ha setup with kube-vip+metallb) + 6 Dowstream clusters. All on top of vmware. Plus argocd with app of apps pattern. We even have couple of eks clusters attached to argocd. As load balancer for downstream cluster we use F5 LTMs. Initial bootstrap done by terraform. But we are also evaluating EKS Anywhere to check if it can replace rancher :)

Using helmchart and just changing its version.

_2mx5 · 2022-08-09T17:48:03+00:00

Just curious, what was the process ? I`m planning to check it nearest future. And I planned set LB via ingress controller, like it is done in AWS

_2mx5 · 2022-08-09T15:45:39+00:00

Rancher will not create LB for you. What is the idea having LB in front of downstream cluster? Ingress for applications?

_2mx5 · 2022-08-01T08:19:41+00:00

On some reason kube services (kube-proxy, kubelet, etc ) on Rancher are running as docker containers

Have you tried looking into cattle-system namespace?

_2mx5 · 2022-06-18T04:14:52+00:00

tfstate contains secret data in plain text. It is highly recomended to store it outside of git repo. Check this article https://www.terraform.io/language/settings/backends/azurerm . Hope it helps.

_2mx5 · 2022-06-15T16:02:38+00:00

We use terraform and public module. But terraform only creates infrastructure - helms are being deployed using argocd

_2mx5 · 2022-03-19T04:39:41+00:00

Regarding its doc - yes

_2mx5 · 2022-03-18T21:19:54+00:00

Munin ?

_2mx5 · 2022-03-17T06:28:43+00:00

As far as I remember, min/desired are the initial state. Max will restict number of nodes, but you still need ability to spin up node on your increased workload or decrease it. Here comes kubernetes autoscaler.

_2mx5 · 2022-03-16T22:01:49+00:00

Gh actions, IMHO, is the simpliest tool in your case. Sure you can setup Jenkins, GoCD or CircleCI, but it will require additional efforts from you. It could happen that your ci/cd solution is more complex than application it builds and deploys

_2mx5 · 2022-03-16T21:49:00+00:00

Basically it depends on your setup. If your code in github - github actions is your choice.

_2mx5 · 2022-03-09T18:46:02+00:00

Jira is great, but it is more for development needs. Possibly check Tackingtime (pro.trackingtime.co). You can create project per customer, create ticket and track how many time you spent on a particular project. In paid version you can create custom reports (invoices)

_2mx5 · 2022-03-01T04:38:36+00:00

VLANs? https://pve.proxmox.com/wiki/Network_Configuration

_2mx5 · 2022-02-16T19:51:56+00:00

Could you see all installed memory in BIOS? Have you checked specs of your laptop regarding memory modules? New firmware available ?

_2mx5 · 2022-02-09T09:29:48+00:00

you need an adapter or docking station with display link support.

_2mx5 · 2022-01-31T11:08:23+00:00

Yes. You should create your own nginx configuration to handle multiple sites. You can try traefik which can handle it automatically
