Here we show you a demonstration of the basic functions of PKS, including the following sections:
  • General introduction of PKS architecture
  • Create a PKS cluster
  • View container images stored in Harbor
  • Example of deploying a restaurant rating application
  • By turning off a PKS node (virtual machine), it shows the high reliability features that PKS brings.
PKS (VMware Pivotal Container Service) is a new enterprise-class container scheduling platform from VMware and Pivotal. It mainly includes the following components:
  • PKS Controller:Provides container platform administrator PRE (Platform Reliability Engineer) with a management interface as a command line or as an API.
  • Kubernetes:PKS supports the latest release of K8s and builds multiple K8s clusters in a PKS environment to support container applications.
  • BOSH:Deploy K8s clusters on the vSphere private cloud or the VMware Cloud on AWS public cloud, and monitor the operation of the K8s cluster to provide HA functions such as cluster repair.
  • NSX-T:VMware's next-generation network virtualization products provide containers with advanced networking capabilities such as micro-segmentation, load balancing, and security policies.
  • Harber:The container image repository, which supports identity-based access control, can scan the container image for security vulnerabilities and provide a secure image service.
  • GCP Service Broker:Enables developers to provision and use the Google Cloud Platform cloud service directly.
An administrator can use a create-cluster command to easily create a K8s cluster. An administrator can use the following command to create a cluster. The parameter n is used to specify the number of workers in the cluster:
# pks create-cluster cluster1 n=3
If you later think that the cluster needs to be expanded, you can use the resize command to change the size of the cluster. For example, the following command expands the cluster1 you just created from three worker nodes to five worker nodes.
# pks resize cluster1 n=5
If a worker in the cluster is not working for some reason, BOSH can monitor this situation, automatically start a virtual machine and deploy a new K8s Worker service on it, and register the new worker with the Master of the cluster. , so that the entire K8s cluster returned to normal.
