{{- and -}}

{{- (with the dash and space added) indicates that whitespace should be chomped left -}} means whitespace to the right should be consumed. Be careful! Newlines are whitespace!

:=

In Helm charts, the := operator is used in the Go templating language to assign a value to a variable. {{- $myVar := .Values.myValue -}} you can use $myVar in your template to refer to the value of .Values.myValue.

Please note that the scope of variables in Helm templates can be complex, and the := operator creates a variable that is only available in the scope where it is defined.
