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!

at 12:14 I think required during scheduling should be marked as hard in that table. Please correct me if I am wrong?

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..
