➡️ Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.
➡️ ETCD is a robust key-value store that is responsible for all data of a Kubernetes cluster. When we talk about cluster data, we are more specifically talking about the cluster state and the cluster configuration. I.e. things like deployments, pod state, node state, and configuration are stored here.
➡️ We should use the ETCDCTL tool to interact with the ETCD cluster. Let’s look at the steps involved in the backup:
➥ Create a data snapshot
➥ Copy the snapshot to a PVC
➥ Restore the snapshot in a new cluster
💫 This video covers everything you need to know about the backup and restoring of ETCD in Kubernetes.💫
You can learn the process in simple and easy steps! Grab your hot mug of coffee and dive into the video🚀

Can you please tell what are the alternatives key value store we can use instead of etcd?

[@rajeshbongurala8491]

If staticpod of etcd is not in /etc/kubernetes/manifest, how to identify where is stored/available ?

[@piyushjain2474]

Under the kubelet config, the static pod location is mentioned you can check there the default location and identify the location.
kubelet config file location: /var/lib/kubelet/config.yaml and search for the staticPodPath: /etc/kubernetes/manifests flag

thanks for the tutorial

[@K21Academy]

Thanks, keep watching!

[@mohammedsuhailbasha4860]

Please make and upload more videos on upgrade self managed kubernetes cluster

[@K21Academy]

Thanks for the suggestion, Stay tuned for more content!!😇

[@jrrr86]

Hi, could you please let me know where I can get the documentation for installing etcd binaries? Thanks in advace

[@K21Academy]

Hey, you can check from here: bit.ly/3ZmZ6RG

[@piyushjain2474]

There are many alternatives in the market for etcd. A few of them are- ZooKeeper, consul, MongoDb, reddit, etc. but ETCD is a famous one for the Kubernetes Etcd’s job within Kubernetes is to safely store critical data for distributed systems. It’s best known as Kubernetes’ primary datastore used to store its configuration data, state, and metadata. Also, production environments by large cloud providers such as AWS, Google Cloud Platform, and Azure and openshift used ETCD as a kubernetes database.

@@piyushjain2474 thanks for the update. If we want to use any azure native then can we go with redis cache instead of etcd?

[@yukselbey913]

Hi, Thank you for the video and your effort. if they specify the certain cert files and the location
Then How to restore it. I try one method but I am not sure. Could you please answer me restoring part? If they request specify the cert files location. How to restore it and How to know which one is trusted file client.crt
Like: /opt/data/server.crt
Like /opt/data/server.key
Like /opt/data/client.crt
ETC
Thanks again

[@vivekb1988]

Thanks for the excellent video..!! Will we be able to restore all our pods,deployments etc using this method..?

[@K21Academy]

Yes, thanks

[@rajeshbongurala8491]

Don't we need endpoints for backup and restore ?
