Your one of the best teacher i have ever seen. Thank you very much 😊
Thanks for your comments 🙏🙏🙏
I have been watching your videos for 2 years, your voice cristal clear and you are very helping nature for who are very poor at less knowledge. In this Kubernetes series you can make videos on kubernetes security as well.
Thank you 🙏
Hi, thank you for the great explanation. nowadays, deployments are becoming mandatory across all domains, irrespective of the teams. As a data scientist, I am also ensuring that I at least understand how things work internally. your explanation, especially since it's in my mother tongue, was easy to understand and very helpful. Thank you for everything. If you don’t mind, could you please share the PPT/Notebook for this? It would make it easier to walk through.

Thank you for watching 🙏
hello charan can you please tell about the difference between the kubespray and kubernetes, Actually my friends using the commands like make kubernetes/kubespray/apply and prepare and like this. i need to know the difference between these two.
Kubespray is deployment tool for kubernetes. Kubernetes is a platform.
In our deployment setup, we have the flexibility to adjust the number of replicas based on your requirements. This means that we can easily change the number of replicas as needed. For example, if you request a reduction in replicas from 4 to 2, we can quickly accommodate this change. Conversely, if after a few months, you require additional pods, we can add 3 more nodes to meet your increased demand.
but i want autoscaling based on the traffic .. can make it video for the same pls
Sure. Please share the good word about the channel if you can 🙏🙏🙏
what will happen if the users were connected to appliction during edit the delpyoment to decrease the replicas.
Automatically redirected to available replicas. Or a very brief downtime will be observed
Hi bro, your video lectures are very good. One small doubt, for e.g. I am having 4 servers (1 Master node and 3 Worker nodes), appudu nenu replicas count enni pedithe better?
Replica count doesn't directly depends on number of nodes. So it can be anything. Thanks for watching! Please share the good word about the channel, if you like the videos.
bro need a playlist on jenkins as well! 💖💖
Will plan
Anna miku kudhirithe scenario based question and answers kuda cheyyandi anna
Will try.
Hello Sir
after creation of file sample_pod.yml tried to deploy , I used the command like below but I'm getting error like 8080 was refused and entered the manifest perfectly but I'm getting this error
kubectl apply -f sample_pod.yml
"The connection to the server localhost:8080 was refused - did you specify the right host or port?"
It's because you haven't connected to the cluster properly. You need to fetch config file first to connect to the cluster and then try executing the pod.yml
Thanks Charan if possible scnario based K8s explain chystra with real time examples
Thank you 🙏
Your explanation is exceptional anna..
How many total videos are there in kubernetes..??
May be 10 total..
What is the difference between replicaset and deployment
Replicaset is what which creates replicas for a deployment. Deployment is a combination of multiple pods.
when you execute command kubectl get nodes how it is connecting to google kubernetes and fetching data
There is an option in gcp cloud console on gke blade called "connect", from that you can copy the command and execute it from your laptop powershell console. However you need to install the gcp powershell module as well to get it working.

Hi Annaya, meeru google k8'S cheptunnaru kada, coming to azure k8's architecture diagram cluster create, nods and pods create cheyadam and working process antha same kada. only cloud will be change right?
Same untundi Reddy. Endukante k8s common across any cloud. Hope this helps. Please share the word if you can 🙏
Please upload the remaining workload components.
On their way every week.

Please do share the good word about the channel if you can.
Anna mana channel lo unna k8s knowledge tho experience yentha pettochu
3 years
Hai Charan, shall we practice these things in K8s playground ..?
Yes ofcourse Sudhakar. Thanks for watching 🙏🙏🙏
hi bro nuvvu pods create chestappudu container created undha yeppudaitha nuvvu yaml file deploy chesavo container yela vacchindha naku koncham ardam kale or container ni pod tho ela connect chesavo akkada koncham confusion undhi please resolve cheyyava bro and thanks for the wonderfull series
Pod is a concept in k8s, container is concept in docker. So in order to manage containers k8s uses pod as a wrapper, because if it does the same thing as docker there will be no difference between k8s n docker. So they use a concept of Pod which is outer layer of container.
Please do share the good word about the channel if you can.
Hi Charan Azure devops lo kubernetes ela use cheyali
Lab 10 video chudandi. Azure devops labs playlist lo.
@NextOps Videos any trainings you will provide bro
I have one more doubt in deployment object is there are any strategies like rolling updates and recreate for new changes and how to upgrade the image to latest version?
Yes there are strategies like you said. Usually canary deployment process is followed when there is a change in images. In canary you will run old and new versions simultaneously and switch to new after you become confident with the image.
I think workload types like daemonset and statefullset will follow this strategies right?
Hi Anna,
i have 3 doubts
1)When we are creating cluster, we mentioned nodes = 2 .
Ante, 1 MASTER NODE and 1 WORKER NODE create avthundha Anna ? (or) Cluster create time lo MASTER NODE automatic ga create ayyi, manam mention chese nodes ni batti WORKER NODES create avthaaya Anna?
2)For ex: We have 2 Worker Nodes and while creating deployment using manifestfile, we mentioned replica-set=5
Then, It will create 3copies in Workernode1 and 2copies in Workernode2. Is it correct Anna ?
3)Is there any command to check, How many pods are running in a specific workernode ?
Thanks for the reply.
yes
