I'm trying learn etcd cluster and encountered "Bootstrapping an etcd cluster". I looked for online explanation but couldn't find any. Can anyone give explanation?
Kubernetes components are stateless and needs a data store to store cluster state. Bootstrapping etcd cluster means setting up ETCD cluster to store kubernetes components,deployments and other objects data

While provisioning a Kubernetes cluster using kubeadm, I get my nodes tagged as "none".I would like to know if there is an option to add a Role name manually for the node.
You can label the node by kubectl label node <name> key=value

I’m new to creating k8s clusters and have want to try it at home. Master would be x86-64, then I have a number of small arm based systems (armv7, armv8, etc.). Can I hook all of these up into a single cluster use kubeadm?
Yes, you can have multiple architectures of Nodes in a single cluster. kubeadm supports multiple architectures since 1.12. However, you will have to either use multi-arch images or build separate architecture-specific images for each architecture when deploying workloads.

Over the last few hours, I have been trying to create a Kubernetes cluster in GCP. But could not successfully create. The error says "Unable to create the cluser". For sometime, I tried using the web cobsole and later switched to using gcloud. But nothing worked.
Can someone help me here? What is the mistake I am committing.
Regards
Raj

It should be now resolved for most users. If you are still having troubles it's recommended to get in touch with support team.

I'm trying to make a Kubernetes multi-cluster, and I need a unique value to distinguish between cluster.
Does Kubernetes provide a UID to distinguish each cluster?
If not, is the best way to separate each cluster by the UID of the kube-system namespace?
if you have multi cluster and in each cluster you have multi user and namespace, and you want to handle switching between them, it is better to use kubernetes contexts, https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/
if you just need something unique about cluster, use certificate authority information(ca.crt or ca.key in /etc/kubernetes/pki/ directory). but be careful those files should be secured

I have a kubernetes cluster created on GCP, it's fully functional, every logs/metrics are enabled on GKE but, when I go to Stackdriver/resources/kubernetes engine nothing is showed, stuck in loading page.
Can someone help me?
Thanks in advance.
It looks like a specific problem with GCP. I assume you don't have enterprise support in that case I recommend opening a ticket with the free trial support. Otherwise, you'll have to sign up for Silver level support which is $150/month
