Helm Support
T4K supports native Helm chart captures and restores. As part of this feature, Trilio captures all previous revisions of the chart and ensures that commands like helm upgrade
and helm rollback
etc. still work correctly after a restore operation.
Helm charts can have dependencies on other charts that are specified as sub-charts. Sub-charts have their own templates and values. More information about Helm charts can be found here.
In order for Helm charts with sub-charts to be supported with TriliioVault, customers must ensure that the Helm charts follow standard practices for documenting dependencies within the chart itself.
For example, the dependent sub-charts must be defined and mentioned in the dependencies section of the Chart.yaml file or requirements.yaml file as shown below:
If sub-charts are bundled together with the main chart in the charts
directory and are not specified in the dependency manifest file, running helm dep list
against the helm chart will provide warnings if there are missing dependencies.
NOTE: Please ensure that all repositories are accessible from the nodes that the T4K pods can run on.
