WCPCTL

A kubectl style command line tool to interact with vSphere 7 with Tanzu Supervisor Cluster.

Now with support for vSphere 7.0 U1.

This can be used to spin up NSX-T or vSphere NW based Supervisor Cluster.

---

vSphere 7 with Kubernetes brings some amazing features that enable you to run K8s nativly on your compute clusters. While the product is amazing, currently most of the interaction to the platform is limited to interaction with the vCenter UI. While the user interactions are minimal, the thought process for this project was to perform those interactions thru a CLI tool. If its a CLI tool, why not make it kubectl style, with simple, user friendly yaml files to provide the configurations and JSON style outputs??

Some guidance inspired from the awesome work of vthinkbeyondvm.com

• Language - Python (tested on v3.7, MacOS, Linux and Windows Server 2016)
• Required modules - requests, json, time, yaml, uuid, argparse, getpass
  • Most are generally available. May require install of yaml using the following - pip3 install -U PyYAML .
  • Windows additionally may require requests. This can be installed by pip3 install requests.

---

Currently the following actions are supported -

• Creation of the Supervisor Cluster
• Creation of Namespaces
• Creation of Harbor registry
• Creation of Subscribed Content Library
• Reconfiguration of Namespaces (Resource config is a WIP)
• Deletion of Namespaces
• Deletion of Harbor registry
• Deletion of Supervisor cluster
• Deletion of Subscribed Content Library
• Describe Namespace(s) (JSON output)
• Describe WCP Registry (JSON output)
• Describe WCP Cluster (JSON output)
• Describe Subscribed Content Library

Setup

• Make sure Python3 is installed and working.
• Make sure the modules listed above are installed. May require pip3 to install.
• Make sure you have admin access to the vCenter server.
• Make sure the workstation where the wcpctl cli will run on has access to the VCenter server.
• Clone this repo.
• Execute chmod +x wcpctl.py if its not already set to execute.
• Modify the YAML config files provided in the sample-config-yaml folder.
• If possible, move the wcpctl.py file a folder in $PATH. E.g. sudo cp wcpctl.py /usr/local/bin
• Execute the wcpctl code.

$ wcpctl.py -h

Sample Examples

To enable/create a Supervisor Cluster

• modify the wcp-cluster.yaml sample provided in the sample-config-yaml folder. Make sure that the following are enabled/configured (as per official docs) -
  • Relevent Content Library
  • NSX configuration

wcpctl.py create some-wcp-cluster-config.yaml -u [email protected]

To disable the Supervisor Cluster,

wcpctl.py delete some-wcp-cluster-config.yaml

To modify Namespace(s)

wcpctl.py apply some-namespaceconfig.yaml

To create a Registry

wcpctl.py create some-regconfig.yaml

To describe Registry

wcpctl.py describe some-nsconfigfile.yaml

To create a WCP content library

wcpctl.py create some-contentlibconfigfile.yaml
