Rancher Kubernetes API compatible with RKE, RKE2 and maybe others?

Overview

kctl

Rancher Kubernetes API compatible with RKE, RKE2 and maybe others?


Documentation is WIP.


Quickstart

pip install --upgrade kctl

Enhancements

This library borrows the dynamic initialization method from the primary rancher-client python library with several enhancements.

  • Async and Sync support via httpx / lazyapi, which can be initialized from a sync environment.

  • All async methods are accessed with async_ prefix of the same sync methods.

  • Inclusion of kubernetes python client which can be called via KctlClient.api, allowing setting of credentials once. Although this use case has not been extensively tested. (or rather, at all.)

  • Dynamic Access of downstream clusters without requiring reinitialization of the client

  • Enables context switching between clusters

  • Lazy caching of the api schema in kctl/kctl/.kctlcache

  • Enables access of v1/v3 api methods within the same client.

  • All returned results are objects, allowing dynamic access of object attributes, rather than strictly dict based.

  • Adds support for fleet namespaces to ensure proper url handling


Credits / Libraries Used

  • rancher-client: inspired dynamic schema initialization

  • kubernetes: included to manage credentials

  • lazyapi: personal library that is used to create the httpx clients.

  • lazycls: personal library that contains a lot of utility functions that enables this library to be as slim as possible.
