The following table lists the open source licenses associated with the libraries and modules currently in use by Palette eXtended Kubernetes (PXK) and the Federal Information Processing Standards (FIPS) compliant version of PXK.
PXK License
PXK is released under the Apache-2.0 license.
PXK Components
All PXK components and supporting open source components are compiled in their native programming language. Below is a list of the core and auxiliary Kubernetes components that are included in PXK.
Core Kubernetes Components
| Component | Description |
|---|---|
| API Server | The API server is the central management entity that receives all REST requests for the cluster. |
| Controller Manager | The controller manager is a daemon that embeds the core control loops shipped with Kubernetes. |
| Scheduler | The scheduler is a daemon that finds the best node for a pod, based on the scheduling requirements you specify. |
| Kubelet | The kubelet is the primary node agent that is deployed on each node. |
| Kube-proxy | The kube-proxy is a network proxy that operates on each node in your cluster, implementing part of the Kubernetes Service concept. |
| Kubeadm | Kubeadm is a tool built to provide best-practice “fast paths” for creating Kubernetes clusters. |
| Kubectl | Kubectl is a command line interface for issuing commands against Kubernetes clusters. |
Auxiliary Kubernetes Components
| Component | Description |
|---|---|
| CoreDNS | CoreDNS is a Domain Name System (DNS) server deployed as a cluster DNS service. |
| Etcd | Etcd is a distributed key-value store used as Kubernetes’ backing store for all cluster data. |
Runtime Components
| Component | Description |
|---|---|
| containerd | Containerd is an industry-standard container runtime with an emphasis on simplicity, robustness, and portability. |
| containerd-shim | Containerd-shim is a shim used by containerd to launch containers. |
| containerd-shim-runc-v1 | Containerd-shim-runc-v1 is a shim used by containerd to launch containers. |
| containerd-shim-runc-v2 | Containerd-shim-runc-v2 is a shim used by containerd to launch containers. |
| ctr | Ctr is a command line interface for containerd. |
| crictl | Crictl is a command line interface for CRI-compatible container runtimes. |
| runc | Runc is a CLI tool for spawning and managing containers according to the OCI specification. |
