Kubernetes Hosting and Storage Questions
I have a few questions regarding the Kubernetes hosting offer.
Currently I have created a standard cluster with 3 nodes.
Version 1.22 $60.00/month 6 CPU cores --> 2 per node 12 GB RAM --> 4 per node 240 GB storage --> 80 per node
While reviewing the nodes, I noticed that none of them have the Master / Control plane role.
Am I correct in assuming that this part is managed by Linode ?
And if so I have 3 worker nodes that I can demolish and rebuild whenever I want ?
Memory management at Linode:
I installed Longhorn and then saw:
Schedulable 148 Gi Reserved 70.8 Gi Used 16.8 Gi Disabled 0 Bi Total 236 Gi
Reserved 70.8 Gi --> for each node 23.6 Gi
For what are the 23.6 Gi reserved on each node ?
This would not be 80 Gi as. stated but actually usable. "only" 55.1 Gi
My assumption is operating system and what is necessary to run the node.
Last question: --> storageclass
Is it safe to set the linode-block-storage-retain from default to no ?
NAME PROVISIONER linode-block-storage linodebs.csi.linode.com linode-block-storage-retain (default) linodebs.csi.linode.com longhorn (default) driver.longhorn.io
Have a nice day ;-)
