Why does my cluster keeps disappearing?

[User16860826802]

My team and I were using a cluster for some days and it disappeared without any apparent reason. I recreate the cluster, but after some days it disappeared again. Do you know why my cluster disappeared? how to avoid that?

A cluster is deleted after 30 days after a cluster is terminated. To keep an all-purpose cluster configuration even after a cluster has been terminated for more than 30 days, an administrator can pin the cluster. Up to 70 clusters can be pinned.

To avoid that, you have to pin the cluster you want to keep.
