Description

It would be very handy if ibm_container_cluster_versions data lookup could be updated to return the current default version. This can be extracted from the json returned by the api (see default values below):

{
    "kubernetes": [
        {
            "major": 1,
            "minor": 24,
            "patch": 16,
            "default": false,
            "end_of_service": "2023-10-11T23:59:59+0000"
        },
        {
            "major": 1,
            "minor": 25,
            "patch": 12,
            "default": false,
            "end_of_service": ""
        },
        {
            "major": 1,
            "minor": 26,
            "patch": 7,
            "default": true,
            "end_of_service": ""
        },
        {
            "major": 1,
            "minor": 27,
            "patch": 4,
            "default": false,
            "end_of_service": ""
        }
    ],
    "openshift": [
        {
            "major": 4,
            "minor": 9,
            "patch": 59,
            "default": false,
            "end_of_service": "2023-08-30T23:59:59+0000"
        },
        {
            "major": 4,
            "minor": 10,
            "patch": 63,
            "default": false,
            "end_of_service": ""
        },
        {
            "major": 4,
            "minor": 11,
            "patch": 44,
            "default": false,
            "end_of_service": ""
        },
        {
            "major": 4,
            "minor": 12,
            "patch": 24,
            "default": true,
            "end_of_service": ""
        },
        {
            "major": 4,
            "minor": 13,
            "patch": 5,
            "default": false,
            "end_of_service": ""
        }
    ]
}

In the UI the default version shows as the recommended version:

New or Affected Resource(s)

Potential Terraform Configuration

default_ocp_version = "${data.ibm_container_cluster_versions.cluster_versions.default_openshift_version}_openshift"
