Pivotal Container Service (PKS)
Page last updated:
Pivotal Container Service (PKS) enables operators to provision, operate, and manage enterprise-grade Kubernetes clusters using BOSH and Pivotal Ops Manager.
PKS uses the On-Demand Broker to deploy Cloud Foundry Container Runtime, a BOSH release that offers a uniform way to instantiate, deploy, and manage highly available Kubernetes clusters on a cloud platform using BOSH.
After operators install the PKS tile on the Ops Manager Installation Dashboard, developers can provision Kubernetes clusters using the PKS Command Line Interface (PKS CLI), and run container-based workloads on the clusters with the Kubernetes CLI, kubectl.
PKS is available as part of Pivotal Cloud Foundry or as a stand-alone product.
The following table details the features that PKS adds to the Kubernetes platform.
|Feature||Included in K8s||Included in PKS|
|Single tenant ingress||✓||✓|
|Secure multi-tenant ingress||✓|
|Stateful sets of pods||✓||✓|
|Rolling upgrades to pods||✓||✓|
|Rolling upgrades to cluster infrastructure||✓|
|Pod scaling and high availability||✓||✓|
|Cluster provisioning and scaling||✓|
|Monitoring and recovery of cluster VMs and processes||✓|
|Secure container registry||✓|
|Embedded, hardened operating system||✓|
PKS has the following features:
Kubernetes Compatibility: Constant compatibility with current stable release of Kubernetes
Production-ready: Highly available from applications to infrastructure, with no single points of failure
BOSH advantages: Built-in health checks, scaling, auto-healing and rolling upgrades
Fully automated operations: Fully automated deploy, scale, patch, and upgrade experience
Multi-cloud: Consistent operational experience across multiple clouds
GCP APIs access: The Google Cloud Platform (GCP) Service Broker gives applications access to the Google Cloud APIs, and Google Container Engine (GKE) consistency enables the transfer of workloads from or to GCP
On vSphere, PKS supports deploying and running Kubernetes clusters in air-gapped environments.
The PKS control plane contains the following components:
- An On-Demand Broker that deploys Cloud Foundry Container Runtime (CFCR), an open-source project that provides a solution for deploying and managing Kubernetes clusters using BOSH.
- A Service Adapter
- The PKS API
For more information about the PKS control plane, see PKS Cluster Management.
For a detailed list of components and supported versions by a particular PKS release, see the PKS Release Notes.
For conceptual information about PKS, see PKS Concepts.
For information about the requirements for installing PKS, see PKS Prerequisites.
To install PKS, you must deploy Ops Manager v2.0 or v2.1. You use Ops Manager to install and configure PKS.
If you are installing PKS to vSphere, you can also configure integration with NSX-T and Harbor.
Consult the following table for compatibility information:
|IaaS||Ops Manager v2.0||NSX-T||Harbor|
|vSphere||Required||Available||Available||GCP||Required||Not Available||Not Available|
