Helm setValueTemplates in dev mode

[Robert Johnstone]

Hello,

I am encountering unexpected behaviour when using skaffold dev. I have created a configuration that uses a local helm chart and substitutes a large number of values into the helm chart using setValueTemplates. I know that this configuration works because skaffold run  works beautifully.

skaffold render also shows the values I expect to see

I find that when I try to use development mode, the values are not passed into the helm chart. It's not that the non-interpolated (Go template) values are provided, rather that no values at all are passed to helm and the default values from the chart are used. Is this expected behaviour? If so, I'd appreciate some pointers to documentation about the best way to do deployment-specific configuration with helm in dev mode.

Cheers
