The command "helm dependency update" is used in the Helm package manager for Kubernetes to update the dependencies of a Helm chart.

In Helm, a chart is a collection of files that describes a set of Kubernetes resources. It can include templates, values, and charts from other dependencies. Dependencies are reusable components that can be included in multiple charts.

When you run "helm dependency update", Helm looks at the dependencies defined in the "requirements.yaml" file of the chart and checks if there are any updates available for those dependencies. If there are updates, Helm downloads the latest version of the dependencies and updates the "charts/" directory within the chart.

This command is useful when you want to ensure that your chart is using the latest versions of its dependencies. By updating the dependencies, you can incorporate any bug fixes, feature updates, or security patches provided by the dependency maintainers into your chart.
