Kubernetes supports deployment from both JSON and YAML files. However, socially, YAML is the more frequently used option and can be considered the standard.
Deploying from YAML is quite similar to a chart.Helm- File.yamlor.ymlIt provides the definition of an object or list of objects (objects), so it can be used directly in the Kubernetes Dashboard or with the kubectl command-line tool without installing additional software.
When working with kubectl, use the commandapplywith the correct path to your deploy's YAML file:
kubectl apply -f /path/to/deployment.yamlOn the other hand, the benefit of Helm charts is their advanced flexibility (supports conditions, replacements, parameters, etc.).
