Package helm provides a higher level interface to the Helm Go SDK.
|
|
|
|
It is used by the CLI to:
|
|
|
|
- load embedded charts
|
|
- install charts
|
|
- update helm releases
|
|
- get versions for installed helm releases
|
|
- create local backups before running service upgrades
|
|
|
|
The charts themselves are embedded in the CLI binary, and values are dynamically updated depending on configuration.
|
|
The charts can be found in “./charts/“.
|
|
Values should be added in the chart's "values.yaml“ file if they are static i.e. don't depend on user input,
|
|
otherwise they need to be dynamically created depending on a user's configuration.
|
|
|
|
Helm logic should not be implemented outside this package.
|
|
All values loading, parsing, installing, uninstalling, and updating of charts should be implemented here.
|
|
As such, the helm package requires to implement some CSP specific logic.
|
|
However, exported functions should be CSP agnostic and take a cloudprovider.Provider as argument.
|
|
As such, the number of exported functions should be kept minimal.
