you are one of those people who make the world a better place!! .. keep it up.. Excellent videos

[@justmeandopensource]

Hi, many thanks for following my videos and taking time to comment/appreciate. Cheers.

[@solidUntilLiquidBeforeGas]

Really enjoy your videos! Very easy to follow and packed with information, while avoiding unnecessary details. On a separate thread, can you please share/post a short video on how you have your zsh configured? Appreciate all you do. Please keep these coming! Kudos.

[@justmeandopensource]

Hi, thanks for watching. I have done a video long time ago about my terminal setup. kzbin.info/www/bejne/qaCkqIinZ8iEfrM But since then I have changed a lot and now I am using Gentoo but zsh and its configurations still remain the same. Basically, its zsh > zsh-autosuggestions > oh-my-zsh I have been wanting to do a video of my current setup which I will at some point. Cheers.

It is bit late I am watching your this video, but still it is relevant. I have a use case. Can we somehow trigger the cron job manually outside its set trigger schedule?

[@justmeandopensource]

Hi Jayesh, thanks for watching. This is a cron job and gets run as per the schedule you defined. If you want to trigger it manually, then there is kubernetes jobs.

[@jayeshthamke7860]

Thanks Venkat! Basically I m thinking of end to end and monkey test scenario and came up with some really weird use-cases. I wonder if u r aware of any opensouce tooling for running end to end tests in a cluster?

[@TheFearali]

Hello Dear, Thanks for your videos! actually u can explain kubernetes like no body else! Anyway I have a question for u. Can we run a job inside specific pod? and how?

[@justmeandopensource]

Hi Majid, thanks for watching. When you create Kubernetes job, it will create a pod (and container within) to run that job and the pod terminates. You can't run a job inside a specific pod. Each container/pod has specific purpose. If you want to alter something inside a running pod/container or get some data off a particular pod/container, then you have to make sure to expose the data from within the container (usually using a Kubernetes service) which can then be accessed by the pod your kubernetes job runs on. Cheers.

[@TheFearali]

[@biswajit4631]

I really enjoy the course. Can you please help me to setup a yaml job , which need to be wait until the job was not finished.

[@VijayYadav-rc2is]

Why we need a jobs? if we can run the pods simply by running the kubectl command and using the replicaset.

[@justmeandopensource]

Hi Vijay, jobs serves specific purpose. Yes you can simply run kubectl command to run a pod. Please explain me how you would achieve the below requirement. This is just for the purpose of understading why jobs/cronjobs are helpful. There is a mysql server running somewhere and I want to do a mysqldump every Wednesday at 10PM. And if something goes wrong with the mysqldump process, I need the ability to look through the logs to find out what happened. Let me know how you would do this using simple kubectl command. Cheers.

[@VijayYadav-rc2is]

@@justmeandopensource Thanks for replying. 1) We can create script and run manually. 2) I got the point,that it can be achived by running cronjob at particular time.

[@justmeandopensource]

@@VijayYadav-rc2is Yeah. Just for automating your manual tasks. You can create a script and run manually. But where would you place the script and how would you trigger the script. Would you place the script on a different machine and execute it via cron? Then what happens if that machine is down? So for things like these, jobs/cronjobs are designed to be run withing the cluster so you don't need any external resources. Cheers.

[@mageshp5998]

Thanks so much for your wonder video, wondering if there is any programmatic way to cleanup completed pod and job

[@saoudahmedkhan2549]

At 11:24 parallelism is 2 Completion is 2 So I runs 2 pod parallel and these two pods completed 2 iterations.. please reply

[@justmeandopensource]

Hi Saoud, thanks for watching. completions 2 means that the workload should be run 2 times. With just completions 2 (and no parallelism), you will have first pod launched, completes the work and then second pod launches and completes the work. Now when you also specify parallelism 2, two pods will launch and run at the same time. Hope this makes sense. Cheers.

[@justmeandopensource]

Hi Sarfaraz, thanks for watching this video. The way I explained in this video is the way it is supposed to work. When you create cronjob, it will create a pod and run it on the schedule you specified in the cronjob manifest.

Hi, Thanks for your training. I'm trying to install a cluster using vagrant up and I have an issue when trying to Deploy flannel network. Could you check it with me please.. kmaster: [TASK 3] Deploy flannel network kmaster: Unable to connect to the server: net/http: TLS handshake timeout kmaster: [TASK 4] Generate and save cluster join command to /joincluster.sh kmaster: timed out waiting for the condition The SSH command responded with a non-zero exit status. Vagrant assumes that this means the command failed. The output for this command should be in the log above. Please read the output to determine what went wrong.

[@justmeandopensource]

Hi Abdel, thanks for watching this video. I will do a vagrant up on my workstation and see if anything has changed. Will updated you shortly. Thanks.

[@justmeandopensource]

HI Abdel, I just tried it on my machine and it worked perfectly fine. My guess is that it didn't fail on the "[TASK 3] Deploy flannel network" but it should have failed before that during Kubernetes initialization. The cluster failed to initialize and hence deploying flannel network failed. To troubleshoot this issue, edit vagrant-provisioning/bootstrap_kmaster.sh script and remove output redirection on Line 5 "kubeadm init command" On that line just remove ">> /root/kubeinit.log 2>/dev/null". Delete all the VMs and run vagrant up again. You should now be able to see exactly why its failing. Thanks, Venkat

Hi Venkat, thanks for the detailed video. A quick question.... If I want to run parallel jobs for this use case, how to do it? Use case: For benchmarking purpose, let's say I have assigned a range for CPU values to do deployments , like 1cpu-100cpu. And I want to do a load test for every CPU value in the given range but I don't want to wait by running deployment one by one with new configuration of cpu value. Instead, want to run jobs parallely in batches like cpu range from 1 to 10 in one batch and cpu range from 11 to 20 in another batch and so on. How can I achieve this parallel batch jobs execution?

What is the learning path and what is the prerequisite

[@justmeandopensource]

Hi Abdul, If you decide to go with Cloud technology and that is where your interests are, then there are lots you can follow to prepare yourself. You can learn AWS, Google Cloud, Docker stuff, Kubernetes etc. If you gain confidence you can then go for certifications like AWS Solutions Architect. Kubernetes certification is also available from CNCF (Certified Kubernetes Administrator). The pre-requisites are that you have some basic knowledge about cloud and containers. Amazon provides free tier for first 12 months to try their AWS resources. Google Cloud also has similar free tier for your to learn. Thanks

[@AmitKumar-zu5uc]

Nice Video. One gotcha at kzbin.info/www/bejne/q3uudmOaa76Sr8k : When you have successfulJobsHistoryLimit and failedJobsHistoryLimit to zero then deployment gets delete automatically and Kubernetes lost the connection between cronjob and pod which were done by jobs that's why you have to delete pods manually otherwise while deleting the job it will delete pod automatically. Two questions apart from this: 1. You are using busybox in this video, why not alpine? 2. How autocomplete works in your laptop? Thanks for your time.

[@justmeandopensource]

Hi Amit, thanks for watching this video. I got used to typing busybox. This is just to show a quick example and didn't bother to use alpine. And for kubernetes auto-completion, I used kubectl plugin for oh-my-zsh on top of my zsh shell. If you are using bash, you can follow the steps in the below link. kubernetes.io/docs/tasks/tools/install-kubectl/ Thanks, Venkat
