                                               throws ChartResolverException

Uses the supplied chartName and chartVersion parameters to find an appropriate Helm chart and returns it in the form of a Chart.Builder object.

Implementations of this method may return null.

Parameters:

chartName - the name of the chart to resolve; must not be null

chartVersion - the version of the chart to resolve; may be null which normally implies "latest" semantics

Returns:

the Chart.Builder representing a suitable Helm chart, or null if no such chart could be found

Throws:

ChartResolverException - if there was a problem with resolution

NullPointerException - if chartName is null

IllegalArgumentException - if either parameter value is incorrect in some way
