      That's great! I wish you all the best for the exam. Please practice all questions on your own. Remember to switch to the required "context" for each question in the exam. Don't spent too much time on a particular question, just flag it to attempt later.
      Give your best and do let me know the results and before results, do let us know if questions in the video are similar to exam questions or not. This will help the community.
      Thanks!

    Hi! I took my CKA exam yesterday, I got the question about ssh into node, and perform back up and restore of etcd with peer.key and peer.crt. If I passed those in when backing up, I received “no such file or directory” error on the peer.crt/peer.key. Any idea what to do here? Can’t find any examples out there that does this either.
    I also tried server.crt and server.key, but all I got was “permission denied”, so I suspect I have to authenticate with the peer flags somehow(?) These peer flags were also not present when checking the etcd pod’s commands. I do see in the docs, under Securing Communication that there are some peer flags for configuring etcd with secure peer comm., but these flags were unknown to the etcdctl tool

    Hi Sir
    Thanks for the video. After following the solution mentioned in video my etcd pod stuck in pending state (after restore). Please help me with this.

    • @iajeetkhan
      @iajeetkhan  8 місяців тому

      Hi, you can run the command - kubectl describe pod . This will describe the pod details and in the event section it will show why it is in pending state. Hope this helps in debugging.
      Thanks

    Hi Guys, Is it anyone gave exam of CKA by referring Ajeet sir videos, I saw this videos , that are helpful to understand but just want to know how much you got help in real time CKA exam by watching this videos, Is it same questions you faced in exam?

    • @iajeetkhan
      @iajeetkhan  6 місяців тому +1

      Hi, These questions are very much similar to what you will face in the exam. All you need to do is at least practice all the questions twice and you should be able to solve all these questions on your own.
      For verification - many people have reported in comments that they have cleared the exams by watching my videos.
      You can also search for "Ajeet Khan CKA" on LinkedIn and you will find many people posting their successful attempt and tagging me to thank me for these videos.
      Rest all depends on your practice. I wish you all the best for the exam. Do share your experience.

    Hi Ajeet, after restoring the backup what we have to do like we have to check via k get po -n kube-system or we have to stop etcd service then edit file and start the service. I am asking as per exam prospective. whatever you do is enough or we have to restart ETCD

    On the exam I am receiving a failed permission to the key file when running backup. Any solution for this issue? Missed it by 1% unfortunately

    • @iajeetkhan
      @iajeetkhan  9 місяців тому +1

      Generally, the permission on key file should be either 400 or 600. You can change the permission by running the command sudo chmod 400 file.key

    In case of backup restore using ETCDCTL_API=3 snapshot restore , we also need to modify path /var/lib/etcd-from-backup
    Do we need to use ssh & use command sudo -i while we enter path /var/lib/etcd to /var/lib/etcd-from-backup
    I tried ssh controlplane but could not find any file under /var/lib

    • @iajeetkhan
      @iajeetkhan  Рік тому +1

      That depends on etcd installation. I suggest you to create your own cluster with etcd and then try with the path you have used during the installation of etcd. I will try to cover installation of cluster with etcd in upcoming videos. BTW, part 7 will be released in couple of days.

      Then you will just need to edit the etcd manifest with the new path and it should work. You can do kubectl describe command on etcd pods to check if its using a new path.
