Values.yaml Files

Values.yaml files generally always contain configuration setting for Helm charts, TrueCharts is no different. However, we have multiple different values.yaml files, with different goals. Because TrueNAS SCALE just works slightly differently from standard Helm Charts

The Files

values.yaml

The normal file with default setting in helm charts. However, for our non-library and non-dependency charts, this is not used for TrueCharts. As questions.yaml generates configs on demand (with addition of ix_values.yaml), this file might interfere with some Helm operations combined with the questions.yaml or test_values.yaml systems or cause unexpected behavior if used.

ix_values.yaml

This file contains config values that are not included in questions.yaml, but should be copied into the resulting configuration anyway. It's mostly used to ensure setting can be changed by the maintainer with every update, such as versions, which is not possible when setting things as defaults inside questions.yaml

This file is, however, not very well checked by validation and CI. Use it when you absolutely have to.

One important setting in ix_values.yaml is the optional setting: startAsRoot: true This setting is a compatibility toggle for containers that need to be started by root, often these containers use PUID and PGID to descalate (lower) away from root but require it to start.

A minimal example ix_values.yaml would be:

##
# This file contains Values.yaml content that gets added to the output of questions.yaml
# It's ONLY meant for content that the user is NOT expected to change.
# Example: Everything under "image" is not included in questions.yaml but is included here.
##

image:
  repository: jacobalberty/unifi
  tag: 6.0.45
  pullPolicy: IfNotPresent


##
# Most other defaults are set in questions.yaml
# For other options please refer to the wiki, default_values.yaml or the common library chart
##

test_values.yaml

Our Apps often use special features of TrueNAS inside questions.yaml and our charts. However these features are not (always) compatible with stock Helm. Therefore we define a set of seperate "test" values.yaml setting that get used when we run the test CI.

They should, however, be as close as possible to your "actual" default settings in questions.yaml

default_values.yaml

This on is the "odd one" of the bunch. We prefer not to use it for actual default, but to store default when porting charts from upstream.
