In this video I cover the how I passed the Certified Kubernetes Administrator (CKA) exam giving practical examples, tips and covering important topics that will help you get through the exam. This is an exam guide but does not fully cover all details related to the exam and as such you must still review the pre-exam instructions prior to taking the exam.

Great vid man! Just so you know, to show the example of the `kubelet` status, you could have just `minikube ssh` or just ssh manually to minikube node, and then check (treated as a control/worker node).

great idea on the function to change to the namespace. i'm also going to put an alias called "cn" so i can see the current namespace i'm in, i think that would be helpful also

At 33:17 you edit a pod and then when it doesnt work make a yaml copy of that you delete stuff from and edit. When you do a "k edit" and it fails, it generates a copy of the file WITH the changes automatically (filename is in the console). You can then just do a "k replace" using that exact file with the --force parameter

Hi can u share tips related to network policy. Generally these questions are really polished and hard to interpret.

@jmmtechnology4539 Жыл бұрын

Hey! I have a video on Network Policies here: kzfaq.info/get/bejne/ncyPesd_ldrXmo0.html. That will give you a conceptual understanding of how they work. When it comes to tackling the questions it's important that you're very familiar with the docs. In the exam you will be able to copy an example from the docs but it's important you're familiar with the structure of the yaml in order to modify to suit your needs. Make sure you know how to select the pods that will have the NetworkPolicy applied to them (ie podSelector) as well as the different ways to select the traffic source that will be allowed to those pods (podSelector, namespaceSelector, ipBlock etc)

great video I was wondering would this work as a function to get the snapshot status with ess as a alias through a function definition: function ess () { etcdctl config set-context --current --snapshot status=$1 }

@jmmtechnology4539 Жыл бұрын

You certainly could, it may not be a command you're using frequently enough in the exam to justify the up front effort of creating a function but that depends on your experience.

Thank you for the video. I am about to take the CKAD, and I am looking for some preparation advice. Also, is it more difficult than the CKA? Or not? Do you have any udemy courses that would target the CKAD? I see that you have in the description the udemy course for CKA. I'm wondering if that one would serve my needs to pass the CKAD. Thank you in advance.

Hi Eduardo, based on my experience with the CKA version I would recommend this course: www.udemy.com/course/certified-kubernetes-application-developer/ although that's not to say there aren't many other good resources out there.
