How can I list all available charts under a helm repo?

First, always update your local cache:

helm repo update

Then, you can list all charts by doing:

helm search repo

Or, you can do a case insensitive match on any part of chart name using the following:

helm search repo [your_search_string]

Lastly, if you want to list all the versions you can use the -l/–version argument:

# Lists all versions of all charts
helm search repo -l 

# Lists all versions of all chart names that contain search string
helm search repo -l [your_search_string]
