创建工作的等价物是什么：

kubectl -n my-ns create job --from=cronjob/my-cron-job my-job

使用javascript kubernetes-client吗？

借助此评论找到了我的问题的解决方案

这就是javascript kubernetes-client的样子，在集群内的 pod 中使用（可能需要 rbac 权限，我在 k8s docker-desktop 上运行，所以不需要）：

const createJobFromCronJob = async (
    cronJobNamespace: string,
    cronJobName: string,
    jobNamespace: string,
    jobName: string) => {
    // next 4 lines can be initialized somewhere else
    const kubeConfig = new k8s.KubeConfig();
    kubeConfig.loadFromCluster();
    const batchV1Api = kubeConfig.makeApiClient(k8s.BatchV1Api);
    const batchV1beta1Api = kubeConfig.makeApiClient(k8s.BatchV1beta1Api);
    try {
        const cronJob = await batchV1beta1Api.readNamespacedCronJob(cronJobName, cronJobNamespace);
        const cronJobSpec = cronJob.body.spec.jobTemplate.spec;
        const job = new k8s.V1Job();
        const metadata = new k8s.V1ObjectMeta();
        job.apiVersion = 'batch/v1';
        job.kind = 'Job';
        job.spec = cronJobSpec;
        metadata.name = jobName;
        metadata.annotations = {
            'cronjob.kubernetes.io/instantiate': 'manual',
        };
        job.metadata = metadata;
        const result = await batchV1Api.createNamespacedJob(jobNamespace, job);
        console.log('job created');
    } catch (err) {
        console.error(`failed to create job: ${err.message}`);
        throw err;
    }
}
