Deploying Cartridge app to multiple k8s clusters
vanyarock01 opened this issue · 1 comments
Tarantool-operator does not support working with multiple k8s clusters. It is necessary to research the possibility of deploying and managing a Cartridge app in multiple k8s clusters.
The complexity of the task lies in the fact that two different k8s clusters are two different systems (etcd, kube-api, etc.), which must be connected so that the topology of a single cartridge application remains correct and flexible.
Correctness means that tarantool nodes from different k8s clusters will be connected in the same way as nodes of one k8s cluster, and there will also be no duplicate instances/replicasets in different k8s clusters.
Flexibility means support for correct scaling of a cartridge application.
The solution must support the main features of the tarantool-operator:
- Correctly deploy a cartridge app to multiple K8S clusters
- Manage the topology of the cartridge cluster (scaling replicas and replicasets)
- Rolling upgrade (would be very nice)
One of the possible approaches to the solution could be using kubefed.
