Good video @kubetrain..!! One doubt I have is that will this restore all the pods and applications that were running in the cluster also...???

[@kubetrain]

This covers just the cluster, it’s assumed we would have the manifests for the workloads saved in git repos as Kubernetes or Helm manifests

Hi, i just watched your 1 video and really got interested for all videos and the way you guided the video so perfect... i have 2 question (1) have made video on real time projects if yes then please share (2) Have you recently updated the CKA and CKAD series because am going to watch and practice all of them now

[@kubetrain]

Real-time is there any thing in specific you are looking at?.. yes k8s videos I have added recently

[@srikanthv8108]

Hi, Could you please help me how to provide the endpoints if i use multi master concept .

[@vivekb1988]

HI @kubetrain, Thanks for the excellent video.. I have a running K8's cluster (1 master and 4 worker) and want to make the cluster high available(using 2 master and a load balancer) without losing any data. Will I be able to make use of this approach..??

[@kubetrain]

Thx, could be somewhat different depending on etcd peerings etc.

[@ajk7151]

awesomw video! thank you very much. btw, are there any tools that automate this process, or do you always do this manually?

[@kubetrain]

There are tools like Velero

[@jinumanimala]

In my question they have asked to restore on base node, not given any context. client certificate & client key has been given. how do we do restoration on client side

[@kubetrain]

We would need the cluster details such as its api server IP/URL in order to connect to it right, which is usually present in the context in kubeconfig

[@TheRazerlg]

Hey! Why dont you use for --cert the file etcd-server.crt?

[@kubetrain]

Coz we need the client certificate for the client(ETCDCTL) to interact with the server(etcd server)

i get this error i changed the permission to rwx-rwx-rwx and i set enforce 0 to seLinux but nothing :/ Error: open /etc/kubernetes/pki/etcd/healthcheck-client.crt: permission denied

[@kubetrain]

Hi ru replicating whats in the video, whats the timer in video you are stuck

[@ayoubcherif1305]

@@kubetrain thank you for your reply in 6:40 Error: open /etc/kubernetes/pki/etcd/healthcheck-client.crt: permission denied

[@kubetrain]

Something with the permission only I believe, can check if its applied properly using ls -l in that dir

[@srikanthv8108]

@@ayoubcherif1305 Even i got the same error, but now fixed it.. Try to run the below command first and take the snapshot again as a sudo user. sudo apt install etcd-client Hope it will work.
