I work on a k8s daemonset whose deployment requires that certain values are changed depending on the k8s cluster provider type (gke, eks, aks, minikube, k3s, kind, self-managed k8s installed using kubeadm on a vm, ... etc).

What is the right way to identify what is the k8s cluster provider type given that kubectl/kubeconfig is already configured?

One option is to use kubectl config current-context view:

CURRENT_CONTEXT_NAME="$(kubectl config current-context view)"
PLATFORM="self-managed"

autoDetectEnvironment(){
    if [[ -z "$CURRENT_CONTEXT_NAME" ]]; then
        echo "no configuration has been provided"
        return
    fi  

    echo "Autodetecting environment"
    if [[ $CURRENT_CONTEXT_NAME =~ ^minikube.* ]]; then
        PLATFORM="minikube"
    elif [[ $CURRENT_CONTEXT_NAME =~ ^gke_.* ]]; then
        PLATFORM="gke"
    elif [[ $CURRENT_CONTEXT_NAME =~ ^kind-.* ]]; then
        PLATFORM="kind"
    elif [[ $CURRENT_CONTEXT_NAME =~ ^k3d-.* ]]; then
        PLATFORM="k3d"
        elif [[ $CURRENT_CONTEXT_NAME =~ ^kubernetes-.* ]]; then
                PLATFORM="self-managed"
        else
                echo "No k8s cluster configured or unknown env!"
                exit 2
        fi  
}

However, this seems hacky and am sure it will not work under all cases. For e.g., for EKS I could not figure out what regex to use.
