[Question] Is there a way to start / stop k3d cluster with persistent state?

[lanphan]

Hello all,

I try k3d now, and I wonder that is it possible for me to keep persistent state of cluster so that I can stop / start anytime I want? Noted that, persistent state of cluster includes all namespace, deployment, pods, services, CRs I already deployed on this cluster.

Thanks so much.

Hey @lanphan,

Thanks for opening this.
Can you please give us some more context here? How can we help or is something not working as expected?

Hello @dtomasi ,

I'd like to express my idea in details as followings:

1. Creating 1 k3d cluster X, using k3d cluster create ...
2. Then, deploy some services on it (such as 1 namespace, 3 deployments, 3 services, some CRs ...)

What I want to know is, does k3d support to stop this cluster, then starting it again with exactly all services I already deployed in step #2 above?

Thanks.

Hi @lanphan 👋
Did you try k3d cluster stop and k3d cluster start already?
As long as you don't delete the containers or do a prune in docker, everything should be there as before when you restart the cluster 🤔

Hello @iwilltry42 ,

I'm trying commands you mentioned. Right now, I could not give you feedback that data of my cluster is still existed after stop/start just because it relates to some other things. I'll give feedback ASAP.

Thanks so much for your help.
