How do I inject ConfigMap data into a Pod's command line arguments?

import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Create a ConfigMap with configuration data
const configMap = new k8s.core.v1.ConfigMap("example-config", {
    metadata: { name: "example-config" },
    data: {
        "configKey1": "configValue1",
        "configKey2": "configValue2",
    },
});

// Create a Pod that uses the ConfigMap data in its command line arguments
const pod = new k8s.core.v1.Pod("example-pod", {
    metadata: { name: "example-pod" },
    spec: {
        containers: [
            {
                name: "example-container",
                image: "nginx",
                command: [
                    "sh", "-c", 
                    'echo $(cat /config/configKey1) $(cat /config/configKey2)'
                ],
                volumeMounts: [
                    {
                        name: "config-volume",
                        mountPath: "/config",
                    },
                ],
            },
        ],
        volumes: [
            {
                name: "config-volume",
                configMap: {
                    name: configMap.metadata.name,
                },
            },
        ],
    },
});
