Talos

Talos is a modern OS for Kubernetes. It is designed to be secure, immutable, and minimal. Talos is a self-hosted Kubernetes distribution that runs on bare metal or virtualized infrastructure. Talos is designed to be managed by a central Kubernetes control plane, which can be hosted on the same cluster or on a separate cluster.

kubectl describe pod my-postgres-postgresql-0 (is very useful in case the pod does get deployed

adding worker nodes

Since “longhorn” stores data on more than one node, we need to add more nodes to the cluster.
