If you use vi you can set the config ':set expandtab' to convert any tabs into spaces. In this way, you can copy and paste from documentation without any problem.

In my vi editor I tried, :set expandtab, nothing happened. I purposely copy pasted text having tab and no difference after setting :set expandtab

"kubectl run" does not create "Deployment" anymore with the latest kubernetes versions, better to update it here too. "kubectl run nginx --image=nginx" => this will only create pod by the way, a very good and helpful video, thanks.

@Laftors Місяць тому

... which of course explains why the 'replicas' flag is not accepted anymore the kubectl run command

For the Unix tips presented at ~20:45, it would be really helpful to show exactly how these can be used in the context of a typical exam question. It's not clear exactly how these commands could be used or why they're useful. This would make for a great follow-up video or blog post.

Great tips, mate ! Would you be able to share the PPT ?

@zahurulhaque6377 4 роки тому

Wonderful tips mate. btw which version of Kube you had on your exam? 1.18?

@ivo.woltring 3 роки тому

Thanks for the tips the 'kubectl run nginx --image=nginx --restart=OnFailure --schedule="* * * * *"' command won't work anymore it is deprecated some extra tips: in vi you can replace all tabs to spaces simply by: :%s/\t/ /g (two spaces between / /) if you want to expand tabs and stuff easily and correctly, just edit .vimrc and place this command there: set ts=2 sts=2 sw=2 et which means: tabstop=2 softtabstop=2 shiftwidth=2 expandtab or perform this command in the vim editor itself on the : but then it is only valid for that session...

I need more explanation on how to do this.

@sagirpathan07 4 роки тому

It's great info, thank you Murali. How much time it will take to prepare for this exam. I have no experience on kubernetes and just started learning

@chaitu909 3 роки тому

Hi Murali, Can you please clarify the following: 1) If I can use the Yaml Definition files of various objects say (volumes, pvc etc) from the official documentation during the CKAD exam. Its very difficult to memorize all the fields, especially sub-fields. 2) Please suggest if all the questions weigh same points or few questions carry more marks than others.

Context are already provided or you need to create them by yourself, and, in case, they give you all the instructions in case? Thank you, A.

@ryan-chase 4 роки тому

@ ~11:00 when you discuss using contexts, I assume that you have previously created the context, mycontext? Otherwise, by only running `kubectl config set-context mycontext --namespace=mynamespace`, without defining a "user" or "cluster", you would not be able to view any existing resources in that namespace even if you have set the "mynamespace" context as your current context (i.e. `kubectl config use-context mynamespace`). Can you please confirm as I think this may cause confusion for viewers?

@johantoday 3 роки тому

It would be better to change the namespace for the current context: kubectl config set-context --current --namespace= When finished, run kubectl config set-context --current --namespace=""

Is this relevant for ABAPers? who are planning to work on SAP BTP

kubectl explain pod.spec.containers --recursive ---> thanks for sharing this command is helpfull

@bhaskartaneja6293 4 роки тому

It seems you have deployed a kubernetes cluster locally. Can you tell , what did you do to set up ? I tried doing so on Win 7 , but it somehow fails with miniukube.

@Rope257 3 роки тому

Make sure you're on Windows 7 Pro, not Windows 7 Home. Pro enables virtualization and allows the Windows Hypervisor feature.

From comments below watch video but do try to practice new commands

@staceyh746 4 місяці тому

Does the test let you know if you have done something correctly so you can fix it if you have not?

@zahurulhaque6377 4 роки тому

I have attempted exam yesterday, command like kubectl run nginx --image=nginx --restart=OnFailure --schedule="* * * * *" would fail in kube 1.18, need to use kubectl create cronjob/deploy/job etc

@MsPiyushgupta 4 роки тому

can you share the ppt with me ?

@Rope257 3 роки тому

Pro-tip: Don't use YAML, use JSON. JSON is not sensitive to white-space.

@4ahmad4 3 роки тому

5th command should be like this: kubectl run nginx --image=nginx --restart=Never --port=80 --namespace=myname --command --serviceaccount=mysa1 --env=HOSTNAME=local --labels=bu=finance,env=dev --requests='cpu=100m,memory=256Mi' --limits='cpu=200m,memory=512Mi' --dry-run -o yaml -- /bin/sh -c 'echo hello world'
