Helm regex match from the beginning until the last occurance of a character

Struggling with Helm to match the word from its beginning to the last occurance of -.

I tried {{- printf "%s" .Release.Name | regexFind "[^-]*$" -}}, but it prints from the last occurrance to the end of the word.

Expected

input : hello-world-here => output: hello-world

input : hello-world-here-and-there => output : hello-world-here-and

Solution

  • Big thanks to @Wiktor Stribiżew for his hints.

    After a lot of investigation, I realized that the Regex is correct, but the signature of function is amazing : 

    {{- regexReplaceAll "-[^-]*$" .Release.Name "" -}}

    and NOT : 

     {{- regexReplaceAll "-[^-]*$"  "" .Release.Name -}}
