[lgarber-akamai]

📝 Description

This pull request implements support for managing LKE Enterprise enterprise clusters, including the following changes:

• New lke/tiers/{tier}/versions and lke/tiers/{tier}/versions/{version} endpoints
• New tier field when creating and reading LKE clusters
• New k8s_version and update_strategy fields when creating, updating, and reading LKE node pools

✔️ How to Test

The following test steps assume you have pulled down this PR locally and run make install.

Unit Testing

make test-unit

Integration Testing

make TEST_COMMAND=models/lke test-int

Manual Testing

1. In a linode_api4-python sandbox environment (e.g. dx-devenv), run the following:

import os

from linode_api4 import LinodeClient, TieredKubeVersion


def main():
    client = LinodeClient(os.getenv("LINODE_TOKEN"), base_url="https://api.linode.com/v4beta")

    versions = client.lke.tier("enterprise").versions()
    target_version = versions[0].id

    cluster = client.lke.cluster_create(
        region="us-mia",
        label="test-lke-cluster",
        kube_version=target_version,
        tier="enterprise",
        node_pools=[
            client.lke.node_pool(
                "g6-standard-2",
                3,
                kube_version=target_version,
                update_strategy="on_recycle"
            )
        ]
    )

    print(cluster)

if __name__ == "__main__":
    main()

2. Ensure a new matching LKE enterprise cluster is created successfully.

Any ideas on workarounds for this?

[lgarber-akamai]

This is a new pattern since the LKE tier path is the first of its kind. Let me know if you have any feedback!
