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? Please help.

Great video! Thanks for sharing! Let me ask you two things, one is how you accomplish kubectl completition + constantly watch kubectl get all ? Thanks!

very thanks Sir.

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

Excellent video! I would like to know how to execute several commands (or a shell script) in order to create a Mysql backup dump I tried many things but when I execute the cronjob It seems that I can´t start a mysql session, by the way Im using OpenShift and the command to login into the Mysql POD is: oc rsh , any idea or any suggestions? thanks a lot

thanks for video, can someone kindly explain difference between spec.activeDeadlineSeconds and spec.startingDeadlineSeconds in cronjob

Bro Many thanks for your video which is really great!!! Please help me out - how do i run any cronjob in Openshift for specific time zone

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.

hi bro, please do a video on "clean-up-finished-jobs-automatically" using TTlController, using 'ttlSecondsAfterFinished' in our yaml file at spec.ttlSecondsAfterFinished. thanks

Great video, Can you please provide a tutorial real scenario like :- nginx pod and particular script to run on specific time. In your tutorial cronjob create a separate pod and cron run's in it. But what if i want to run the cronjob on particular pod like :- nginx pod

How to run a job for rolling upgrade in kubernetes cluster?

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?

Hi, I have a python script with some arguments which needs to be run inside the pod/container. Can you please tell me job.yaml file syntax ?? How to execute this python script ?

We can add volume in job section and we can able to mouth same volume in main container ? I tried to add emptdir it fails to loads . Can able to help s on this .

Like your accent brah!!

In my case pods already running Now I want to run Cron to send email so in this case if I set the job and job will be executed , will it create new pods every time ? Or it will be executed on running pods ?

Hi bro please make and upload videos on service discovery in kubernetes.we need your tutorial videos in this topic very much.

greate video, i have a question, how can you deploy multiple cronjobs ?

Can we write YAML files without using colon. Like "apiVersion batch/v1" instead of "apiVersion:batch/v1"?

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.

Thanks for this session, can you explain "startingDeadlineSeconds" this too

Hi, video was very well explained. thanks for that. I just have 2 questions, first, will the pod that is scheduled to get terminated in cronjob will get terminated if pod is in Running/CrashLoopBackOff status and the next scheduled pod to spin up? and second, how to design "schedule" to spin up a pod immediately as we deploy cronjob.yaml and then 2 hours thereforth?

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?

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

What is restartPolicy= Never says. I also see that the RESTART count is not increasing.. Is that mean that on falling that pod "Do not restart pod"?

Im following your Kubernetes tutorial and just to ensure i get all in, i want to do it in Linux too (right now doing in windows). May i know what flavor of Linux are you using?

Hello!!! My Question is irrelevant to this Video Topic, But I'm hopping You may help me in this, Laravel FFMPEG Error Encoding Failed using Laravel Queue in Docker I am running my laravel application on docker container. I am using ffmpeg build johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz i can confirm that ffmpeg and ffprobe are installed. when I submit video to my application it is passed to a queue which is responsible to converts two versions one is 720,1280 and other is 640, 360 what is happening at the moment, I am successfully able to convert uploaded files into 720,1280 but when it comes to converting 640,360 it throws Encoding Failed error. I have switched conversion pattern like first I m trying to convert 640,360 then trying to convert 720,1280. what have I noticed is that first conversion happens successfully, the exception is always thrown at second conversion here is my code sample $format ->setKiloBitrate($bit_rate) ->setAudioChannels(2)->setAudioKiloBitrate(128); $seven_twenty = new Dimension(1280, 720); $video->filters()->resize($seven_twenty)->synchronize(); $video->save($format, $this -> Video['destination'].'-720-1281.mp4'); $format ->setKiloBitrate($bit_rate) -> setAudioChannels(2) -> setAudioKiloBitrate(128); $three_sixty = new Dimension(640, 360); $video->filters()->resize($three_sixty)->synchronize(); $video->save($format, $this -> Video['destination'].'-360-640.mp4'); can You please help me on this.

Who's watching this masterpiece in 2023?

Nice Video. One gotcha at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uJKE0d6Y_yg.html : 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.
