The command helm repo update
is used in the Helm package manager to update the local cache of available charts (package repositories) from the configured repositories.
When you run helm repo update
, Helm checks each configured repository for any updates or changes in the charts it hosts. It fetches the latest information for the charts, such as the chart name, version, description, and the source URL. It also determines if any new charts have been added or if existing charts have been modified.
Updating the repository cache helps ensure that you have the latest and most accurate information about available charts from the configured repositories. It also allows you to search, install, and deploy charts more effectively, as you will be working with the most up-to-date data.
