Advanced Scheduling in Kubernetes

#kubernetes #scheduling #devops #fullstackdevelopment

In the Kubernetes Architecture chapter of this series, we’ve learned that Kubernetes scheduler is responsible for scheduling pods onto nodes. But how does scheduler picks up the best node suitable for our pod? And is it possible to customize this behavior? In this section, we’ll learn how Kubernetes scheduler works, and also we’ll learn how we can customize this behavior using:
1. nodeName
2. nodeSelector
3. Affinity
4. Taints and Tolerations

And needless to say, we'll learn everything with complete Hands-on!

Your videos are crystal clear with the concepts..

[balakrishnag]

Thank you Pavan, crystal clear your concept, . What about node antiaffinity .

[srinivasuluakkula]

@Pavan Elthepu, You are videos are great. Thank you so much for your efforts.
at 12:14 I think required during scheduling should be marked as hard in that table. Please correct me if I am wrong?

[satishvutti]

@PavanElthepu thanks for your efforts..is it possible to make videos on local k8s cluster or rancher instead of aws or aks for quick practice

[RaviSharma-thfi]

Please cover deployment strategy and kubernetes network policy also

[ye__in]

Great content Pavan! Thank you! By the way, could you tell me the k8s yaml extension you’re using? Mine doesn’t have auto complete function for k8s yaml format.

[AnilKumar-wmh]

Hi Pavan, will you provide online classes for AWS & DevOps?

[jalandharbehera]

Please make a video that how we increase pods more than 110 pods in a node

[Mohammed-coux]

Hey buddy please make a detailed video on Helm charts

[ameyabhyankar]

16:58 = May I know how did you fix the indentation? Thank you.

[rohanrustagi]

sir pod affinity and node affinity both works on labels so how come they are different?

[ArvindDeokule]

i tried same with nodeSelector field
please help me to resolve

in my case there is 4 node cluster architecture, one is master and remaining are workers,
i created pv on worker2, and i want to schedule all pods of application on worker1

i labeled worker1 as
kubectl label node worker1 worker1: tmlabs-hp-280-g2-mt
----
#deployment.yaml
nodeSelector:
worker1: tmlabs-hp-280-g2-mt

Error::::
0/4 nodes are available: 1 node(s) didn't match Pod's node affinity/selector. preemption: 0/4 nodes are available: 1 Preemption is not helpful for scheduling, 3 No preemption victims found for incoming pod..
