description: A Helm chart of Mithun tech no for Kubernetes | ||
|
||
# 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. | ||
type: application | ||
|
||
# This is the chart version. This version number should be incremented each time you make changes | ||
# to the chart and its templates, including the app version. | ||
# Versions are expected to follow Semantic Versioning (https://semver.org/) | ||
version: 0.1.0 | ||
|
||
# This is the version number of the application being deployed. This version number should be | ||
# incremented each time you make changes to the application. Versions are not expected to | ||
# follow Semantic Versioning. They should reflect the version the application is using. | ||
appVersion: latest |
