Thanks 🙏 for presenting in a clear manner. 🎉🎉🎉 Lets consider if few pods are running 🏃 before taint on the node. In such case after adding taint what will happen to those pods present inside the node before applying taint?

Hi , I want to create a single pod use to run multiple container as different apps and those all could be access from external or internal IP's , how can we achieve the requirements , please guide me.

@kubetrain 2 ай бұрын

I think we can use one service with different target ports one for each container and keep the service as load balancer or point from an ingress to cluster ip service… may be you already completed this…

@vikaschauhan3290 9 ай бұрын

I have installed a minikube and simply run the same yml file for service with Nodeport as same as you. My issue is when I curl my container using Nodeip:nodeport it is accessible but I am unable to access the container by using the public DNS of ec2:Nodeport and also curl podIP:Nodeport it showing nothing. Also showing nothing curl podIP:80.

@kubetrain 9 ай бұрын

Is your public dns resolving directly to the node ip that worked… secondly pod ip and node port combination wont work, it only works with node ip

Hi i have one question if we create a pv of 20Gb and pvc of 10Gb why pvc consume all capacity of pv?and how to restrict the pvc not to consume all capacity of pv?

@kubetrain Жыл бұрын

It depends on the pvc spec. If you are looking for minimum 10gb it would check for available pvs that can offer min 10gb and use it… the actual utiliziation is different you can check the underlying storage / disk utilization

Did you try with nodeport as the port number? Are you trying to access the private IP or public IP of the node. Is the firewall rule setup for allowing access to the nodeport range.

you`re having three pods here for the sts with the help of headless service how can u point it to one pod among 3?? and how to verify the request is going to only one pod ?? coukld you kindly please reply

@kubetrain Жыл бұрын

A service is commonly used to distribute traffic to multiple pods, if you need only one you can set the replicas to 1. Or If you are interested in accessing only 1 out of 3 you can you check as the pod name. The dns for pod is podname.servicename

hi, your video is so great! One question from me that why in type nodeport use access to app using the random port creating by k8s whereas in Load balancer we dont excess it via the random port instead using definition port?

@kubetrain 2 жыл бұрын

Thx, we can also provide fixed port to nodeport but it causes conflict when two services have the same port coz the node ip could be same, where as with loadbalancer the ip itself is different hence no conflict. It’s recommended to go with random port for nodeport as k8s takes the overhead of assigning unique ports and we don’t have to maintain the list separately

@amitjain8858 Жыл бұрын

Nodeport has a default range 30000-32767, for 8080 you can better use cluster ip or load balancer
