This YAML file contains all the necessary components neatly separated by `---` which indicates the start of a document within the stream in YAML. Ensure that this configuration is applied to your Kubernetes cluster by saving it to a file and using `kubectl apply -f <filename>.yaml`. Adjust the password and other configurations as needed to suit your specific security and operational requirements.
