The .helmignore file

The .helmignore file is used to specify files you don't want to include in your helm chart.

If this file exists, the helm package command will ignore all the files that match the pattern specified in the .helmignore file while packaging your application.

This can help in avoiding unncessary or sensitive files or directories from being added in your helm chart.

The .helmignore file supports Unix shell glob matching, relative path matching, and negation (prefixed with !). Only one pattern per line is considered.

Here is an example .helmignore file:

# comment
.git
*/temp*
*/*/temp*
temp?
