I have ~20 yamls in my helm chart + tons of dependencies and I want to check the rendered output of the specific one. helm template renders all yamls and produces a hundred lines of code. Is there a way (it would be nice to have even a regex) to render only selected template (by a file or eg. a name).

The $_ is used to suppress undesired output as "set" returns the new dictionary.
The tpl function allows developers to evaluate strings as templates inside a template. This is useful to pass a template string as a value to a chart or render external configuration files. Syntax: {{ tpl TEMPLATE_STRING VALUES }}
{{- (with the dash and space added) indicates that whitespace should be chomped left, while -}} means whitespace to the right should be consumed. Be careful!
These files are used to store partials and helpers. In fact, when we first created mychart , we saw a file called _helpers. tpl . That file is the default location for template partials.
From helm template documentation
-s, --show-only stringArray only show manifests rendered from the given templates
For rendering only one resource use helm template -s templates/deployment.yaml .
