The Bare Metal Operator implements a Kubernetes API for managing bare metal hosts.
It maintains an inventory of available hosts as instances of the BareMetalHost Custom Resource Definition.
Kubernetes Resource Recommender
Kubernetes Resource Recommender is a CLI tool for optimizing resource allocation in Kubernetes clusters.
It gathers pod usage data from Prometheus and recommends requests and limits for CPU and memory.
This reduces costs and improves performance.
k0smotron allows you to create and manage clusters in an existing Kubernetes cluster easily.
This allows unparalleled scalability and flexibility when working with many clusters.
Sealed Secrets provides declarative Kubernetes Secret Management in a secure way.
Since the Sealed Secrets are encrypted, they can be safely stored in a code repository.
Kubernetes Secrets Store CSI Driver
kubernetes-sigs
The Secrets Store CSI Driver allows Kubernetes to mount multiple secrets, keys, and certs stored in enterprise-grade external secrets stores into their pods as a volume.
Once the Volume is attached, its data is mounted into the container's file system.
