| description: A Helm chart 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: "v1.17.3" |
