# A chart can be either an 'application' or a 'library' chart.
|
||||
#
|
||||
# Application charts are a collection of templates that can be packaged into versioned archives
|
||||
# to be deployed.
|
||||
#
|
||||
# Library charts provide useful utilities or functions for the chart developer. They're included as
|
||||
# a dependency of application charts to inject those utilities and functions into the rendering
|
||||
# pipeline. Library charts do not define any templates and therefore cannot be deployed.

|
||||
# This is the chart version. This version number should be incremented each time you make changes

# Versions are expected to follow Semantic Versioning (https://semver.org/)

# This is the version number of the application being deployed. This version number should be
