sample-tenant-argo

ArgoCD Version of the sample tenant chart. It demonstrates the use of umbrella charts to customize default values for your environment or tenant templates.

sample-tenant-argo Chart Configuration

You can customize / configure sample-tenant-argo by setting configuration values on the command line or in values files, that you can pass to helm. Please see the samples directory for details.

In case there is no value set, the key will not be used in the manifest, resulting in values taken from the config files of the component.

Template Functions

You can use template functions in the values files. If you do so, make sure you quote correctly (single quotes, if you have double quotes in the template, or escaped quotes).

Global Values

All values can be set per component, per instance or globally per environment.

Example: global.ingress.domain sets the domain on instance level. You can still set a different domain on a component, such as administrator. In that case, simply set ingress.domain for the administrator chart and that setting will have priority:

Prio 1 - Component Level: ingress.domain
Prio 2 - Instance Level: global.ingress.domain
Prio 3 - Environment Level: global.environment.ingress.domain

Using Values in Templates

As it would be a lot of typing to write .Values.ingress.domain | default .Values.global.ingress.domain | default .Values.global.environment.ingress.domainin your template code, this is automatically done by nplus. You can simply type .this.ingress.domain and you will get a condensed and defaulted version of your Values.

So an example in your values.yaml would be:

administrator:
  waitFor:
    - '-service {{ .component.prefix }}nappljobs.{{ .Release.Namespace }}.svc.cluster.local:\{{ .this.nappl.port }} -timeout 600'

This example shows .this.nappl.port which might come from a component, instance or global setting. You do not need to care. The .Release.Namespace is set by helm. You have access to all Release and Chart Metadata, just like in your chart code.

The .component.prefix is calculated by nplus and gives you some handy shortcuts to internal variables:

.component.chartName The name of the chart as in .Chart.Name, but with override by .Values.nameOverride
.component.shortChartName A shorter Version of the name - nappl instead of nplus-component-nappl
.component.prefix The instance Prefix used to name the resources including -. This prefix is dropped, if the .Release.Name equals .Release.Namespace for those of you that only run one nplus Instance per namespace
.component.name The name of the component, including .Values.nameOverride and some logic
.component.fullName The fullName inlcuding .Values.fullnameOverride and some logic
.component.chart Mainly the Chart.Name and Chart.Version
.component.storagePath The path where the component config is stored in the conf PVC
.component.handler The handler (either helm, argoCD or manual)
.instance.name The name of the instance, but with override by .Values.instanceOverride
.instance.group The group, this instance belongs to. Override by .Values.groupOverride
.instance.version The nscale version (mostly taken from Application Layer), this instance is deploying.
.environment.name The name of the environment, but with override by .Values.environmentNameOverride

Keys

Key	Description	Default
