How do you deploy a workload to Kubernetes without additional tools?

Running a Bash script directly on a worker node bypasses the Kubernetes control plane and is not how workloads are managed within the Kubernetes ecosystem.

Helm Charts are a package manager for Kubernetes and are considered an 'additional tool,' making this answer incorrect for deploying without such tools.

`kubectl` is the primary command-line tool for interacting with a Kubernetes cluster, and creating a manifest file (e.g., YAML) that defines Kubernetes objects (like Deployments, Pods, Services) and then applying it with `kubectl apply -f <manifest-file.yaml>` is the native, out-of-the-box way to deploy workloads.

Running a Python script with `kubectl` is not a standard Kubernetes deployment method; `kubectl` executes commands against the cluster API, not arbitrary scripts for deployment logic.
