Cosmos Operator is a Kubernetes Operator primarily for blockchains built with the Cosmos SDK. It also supports Penumbra and other chains which use CometBFT for consensus.
The long-term vision of this operator is to allow you to "configure it and forget it".
Kubernetes provides a foundation for creating highly-available, scalable, fault-tolerant applications. Additionally, Kubernetes provides well-known DevOps patterns and abstractions vs. traditional DevOps which often requires "re-inventing the wheel".
Furthermore, the Operator Pattern allows us to mix infrastructure with business logic, thus minimizing human intervention and human error.

CosmosFullNode is the flagship CRD. Its purpose is to deploy highly-available, fault-tolerant blockchain nodes.
The CosmosFullNode controller is like a StatefulSet for running Cosmos SDK blockchains.
A CosmosFullNode can be configured to run as an RPC node, a validator sentry, or a seed node. All configurations can be used as persistent peers.
As of this writing, Strangelove has been running CosmosFullNode in production for over a year.
Each pod requires different config, such as peer settings in config.toml and mounted node keys. Therefore, a blanket template as found in StatefulSet did not suffice.
Additionally, CosmosFullNode gives you more control over individual pod and pvc pairs vs. a StatefulSet to help the human operator debug and recover from situations such as a corrupted PVCs.
These CRDs are part of the operator and serve to support CosmosFullNodes.
