Configuration settings for Kaptain

This page lists Kaptain configuration properties that can be adjusted during the initial installation or by updating the existing instance of Kaptain. These parameters are typically set in values.yaml.

NOTE: For the properties that require user credentials, ensure that the admin or a person with sufficient administrative rights has modified the initial or default user passwords.
