Can I make my Container Engine Cluster down in night (sleep mode) ?

[sup...@bitpod.io]

hello,

I have created a container engine cluster with 5 nodes, using n1-standard-8 machine type. The machine is generally for development purpose.

Is there any way, in which i can make my clusters down(sleep mode) during night time. And start them in the morning ?

I have tried by stopping the VM's associated with the cluster, but as soon i stopped it, it will re-create it.

Conditions :

1. I have a lot of pods, which should not affect, when i restart the cluster next day.

2. Also, some pv's are associated with the pods.

Any help will be appreciated!

Thanks.

Does GKE let you scale the cluster to 0 nodes? I'm not very familiar with GKE in particular but since it manages the size of the cluster (and replacing lost nodes) I think you just need to tell it what you want instead of going behind it's back.

With autoscaling enabled for your cluster you can scale down a certain node pool to 0 (beginning with Kubernetes version 1.7), but not the whole cluster (there will always be at least one node needed) since there are system pods that need to be scheduled. 

See: https://cloud.google.com/container-engine/docs/cluster-autoscaler#minimum_and_maximum_node_pool_size

This can work for your use case if you can accept a one node cluster working overnight.

Thanks Beata Skiba,

Will this means, that all the users pods created by either stateful-set or replica-set, will be scheduled to the one node, that is used for system pods ?

I was thinking that, if i made node-pool =0, it will down everything. We have auto-scaling enabled in our clusters.

Thanks Again!
