Is there any way I can get the OS details from helm. say Ubuntu 16.04.5 LTS is the OS image used, how can I get this from helm.
I know there is Capabilities.KubeVersion which has the details on platform but it gives
Platform:"linux/amd64"which is not I am looking for.
Short answer, no.
The feature Capabilities from Helm has only Major, Minor, GitVersion, GoVersion, Compiler and Platform info. Platform uses runtime.GOOS and runtime.GOARCH from Go that return only if OS is a Linux type, not its distribution.
