The important thing is to show how leases can be used to coordinate a two-replica app to have one active and one passive replica.

This is super confusing and misleading. You can't create a PVC without a Storage Class. When a PVC does not specify a storageClassName, the default StorageClass is used

What's the reason for a lease to be used by node? For kube API to know the status of the node, can't kubelet of that node just send the requests directly to the API server instead of updating the lease? I can't see how the lease is helpful for nodes. Although I agree with you for distributed case we need leases.

@jmmtechnology4539 6 ай бұрын

Good question, my understanding is that the main reason for using the lease API is for performance, in particular for larger clusters. You can find a detailed explanation on why leases are now used for node heartbeats here: github.com/kubernetes/enhancements/tree/master/keps/sig-node/589-efficient-node-heartbeats

@anveshreddyoffofficial6581 6 ай бұрын

@@jmmtechnology4539 I did check it out and as you said it's because of the performance. They used to do this earlier but because of etcd going out of storage easily due to these update frequency being just 10s and it has to store this info. They moved away from it by introducing a lease for this. Great read!. Thanks a lot for the resource. Would love if you make more videos on these concepts explaining things internally, why they did what they did. Thanks a lot.

I don't think the controller manager can provision a new node by itself if one dies. I think it has to work with a cloud Kubernetes managed service to do so, like EKS or AKS or GKE.

@jmmtechnology4539 6 ай бұрын

Hey John, yes you're bang on with that. My apologies for the mistake here. I cover the cloud controller manager in a bit more detail in this video kzbin.info/www/bejne/mojHe4CaqteKetk and the information should be accurate.

@jmlineb 6 ай бұрын

Hello! Great series of videos, thanks. One reaction to this one. I don't think that Kubernetes by itself can replace a node that has gone down. For that I think it relies on a managed cloud service in which it is embedded, like EKS or AKS or GKE.

Can I send an alert to multiple receivers as well? For example I have a receiver called NYC and another receiver PROD. If I have an alert with the label city=nyc and env=prod I'd like to send this alert to the receiver NYC and to receiver PROD. How could I achieve that?

Great video, why do you think the scheduler lives on its own rather than inside the controller manager? After all, it seems to fit into the job of reconciling the state of pods by assigning a node. Seems like this logic could fit inside a Pod controller of some sort

@jmmtechnology4539 6 ай бұрын

Hi Milan, that's a great question, I believe the scheduler and controllers have sufficiently distinct characteristics and responsibilities such that those who designed and implemented kubernetes thought they should remain separate. For example, the controllers are generally responsible for maintaining cluster state whereas the scheduler has the specific job of placing pods on the correct node. This respects the patterns of decoupling and modularity that are ubiquitous in software design.

But what about the auto scaling of the nodes, in that scenario as well we will face that issue ?
