Re: How to restore single Kubernetes node?

Volumes die, get corrupted, etc. There may come a time when you have to
destroy the volume and re-create it from a snapshot, or launch a new empty
volume and re-stream the data from replicas (using the replace boot flags)

It really depends on how you've set up your Kubernetes cluster. For example
if you're using the k8ssandra (https://k8ssandra.io/) with persistent
volumes, the cass-operator should launch a new pod automatically and mount
the same volume to bring the C* node back online.

But it really depends on several factors such as why the node is
unavailable, what you mean by "restore", etc. Cheers!

Someone will correct me if I'm wrong, but I don't believe any of the
Cassandra operators currently support backup and restore. You'll have to
perform a traditional node replacement.

How to restore single Kubernetes node?

[Pushpendra Rajpoot]

Hi All,

In standard deployment (VM), I backup & restore a single Cassandra node. I
am exploring how I can restore a pod in the Kubernetes cluster but I could
not find any relevant information.

Please share your thoughts/views on how this should be done in Kubernetes.
Any reference or pointer is highly appreciated.

Regards,

Pushpendra
