# Three Level Dependent Chart
|
||||
|
||||
This chart is for testing the processing of multi-level dependencies.
|
||||
|
||||
Consists of the following charts:
|
||||
|
||||
- Library Chart
|
||||
- App Chart (Uses Library Chart as dependecy, 2x: app1/app2)
|
||||
- Umbrella Chart (Has all the app charts as dependencies)
|
||||
|
||||
The precendence is as follows: `library < app < umbrella`
|
||||
|
||||
Catches two use-cases:
|
||||
|
||||
- app overwriting library (app2)
|
||||
- umbrella overwriting app and library (app1)

# 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.
