The value of `metadata.name`, `hello-world`, will be the name of the pod resource created, and must be unique within the cluster, whereas `containers[0].name` is just a nickname for the container within that pod. `image` is the name of the Docker image, which Kubernetes expects to be able to pull from a registry, the [Docker Hub](https://registry.hub.docker.com/) by default.
