Velero + Crossplane

[displague]

Topic

In a rejected Kubecon San Diego proposal, I wanted to explore cluster migration at the trigger of a change in Crossplane resource classes.

Using an independent bucket, also provisioned by Crossplane, a single KubernetesCluster would be modified and the backing cluster would need to be archived, restored to a replacement cluster, and destroyed at the original location.

I believe there may be some rough edges in attempting to do this today, but those rough edges could inspire additional Crossplane features.

With some hand-holding, this concept could be possible using Velero (formerly Heptio Ark) as the archival mechanism.

I think this would make for a very interesting TBS episode.
