What is the next step after setting up K8 2 Node Cluster?
What username & password need to be use for Git clone funnel network. Please confirm.
I was able to setup the cluster but while creating the pod am getting the following error:
Failed to create pod sandbox: rpc error: code = Unknown desc = failed to setup network for sandbox "32b378243ce2f5d046595740e03d9acd1b21b2f84c83926deea3de7296da0312": plugin type="flannel" failed (add): loadFlannelSubnetEnv failed: open /run/flannel/subnet.env: no such file or directory
Can you help me with this.
it doesn't work for me failed exactly kubeadm init last 24:53
[preflight] Running pre-flight checks

@TechArkit, Thank you very much for the fantastic tutorial. I encountered a few challenging moments while trying to follow the steps from the GitHub repository, and it seems they may need updating or alignment. I also ran into some problems when joining the nodes to the cluster, but I managed to resolve them.
Here is what I did:
1. containerd config default > /etc/containerd/config.toml
2. systemctl restart containerd
3. systemctl daemon-reload
4. systemctl status containerd
5. kubeadm join 192.x.x.x:6443 –token 2xwk38.xxxxxxxxxxxxx –discovery-token-ca-cert-hash
how did you resolve the issue for kubelet not running. You did not show the debugging steps for it.
why do we need to install vmware tools can the installation could be perform without them
The file is not available on the repo
Hello please make complete series on docker and kubernetes. thank you
thanks so much!!
I met the containerd error, and i couldn't fix this for 2 days until I found your video. U're great!!!
Awesome dude…..wishing you all the very best …. although I have learnt linux from your side ..I know that you will teach k8s concept easy way in these videos…
