Declarative environment variables

Use envs in OlaresManifest.yaml to declare the configuration parameters, such as passwords, API endpoints, or feature flags. During deployment, app-service resolves the values and injects them into .Values.olaresEnv in values.yaml. Reference them in Helm templates as {{ .Values.olaresEnv.<envName> }}.

Variable sources

Declarative variables can obtain values from configurations managed outside the application:

• System variables: Environment variables defined at the Olares cluster level. They are set during system installation or centrally managed by administrators, and are shared by all users within the cluster.
• User variables: Environment variables defined at the Olares user level. They are managed individually by each user, and are isolated from one another within the same cluster.

Applications cannot modify these variables directly. To use them, map the variable via the valueFrom field.

Map environment variables

Both system environment variables and user environment variables use the same mapping mechanism via valueFrom.

The following example maps the system variable OLARES_SYSTEM_CDN_SERVICE to an application variable APP_CDN_ENDPOINT:

1. In OlaresManifest.yaml, declare an app variable under envs and set valueFrom.envName to the system variable name.

   # Map system variable OLARES_SYSTEM_CDN_SERVICE to app variable APP_CDN_ENDPOINT
   olaresManifest.version: '0.10.0'
   olaresManifest.type: app
   
   envs:
     - envName: APP_CDN_ENDPOINT
       required: true
       applyOnChange: true
       valueFrom:
         envName: OLARES_SYSTEM_CDN_SERVICE

2. In your Helm template, reference the app variable via .Values.olaresEnv.<envName>.

   # Use APP_CDN_ENDPOINT in a container environment variable
   env:
     - name: CDN_ENDPOINT
       value: "{{ .Values.olaresEnv.APP_CDN_ENDPOINT }}"

At deployment, app-service resolves the referenced variable and injects the value into values.yaml:

# Injected by app-service into values.yaml at deployment
olaresEnv:
  APP_CDN_ENDPOINT: "https://cdn.olares.com"

For the full list of available environment variables, see Variable references.

Declaration fields

The following fields are available under each envs entry.

envName

The name of the variable as injected into values.yaml. Reference it in templates as {{ .Values.olaresEnv.<envName> }}.

default

The default value for the variable. Provided by the developer at authoring time. Users cannot modify it. Used when no value is supplied by the user or by valueFrom.

valueFrom

Maps this variable to a system or user environment variable. When set, the current variable inherits all fields from the referenced variable (type, editable, regex, and so on). Any fields defined locally on the current variable are ignored. default and options have no effect when valueFrom is used.

Example: map the app variable APP_CDN_ENDPOINT to the system variable OLARES_SYSTEM_CDN_SERVICE.

# Map app env APP_CDN_ENDPOINT to system variable OLARES_SYSTEM_CDN_SERVICE
envs:
  - envName: APP_CDN_ENDPOINT
    required: true
    applyOnChange: true
    valueFrom:
      envName: OLARES_SYSTEM_CDN_SERVICE

required

Boolean. When true, the variable must have a value for installation to proceed. If no default is set, the user is prompted to enter one. After installation, the value cannot be set to empty.

editable

Boolean. When true, the variable can be modified after installation.

applyOnChange

Boolean. When true, changing this variable automatically restarts all apps or components that use it. When false, a change only takes effect after the app is upgraded or reinstalled. Stopping and starting the app manually has no effect.

type

The expected type of the value. Used for validation before the value is accepted. Supported types: int, bool, url, ip, domain, email, string, password.

regex

A regular expression the value must match. If validation fails, the value cannot be set and installation or upgrade may fail.

options

Restricts the variable to a fixed list of allowed values. The system presents users with a selection UI.

Example: a dropdown list of supported Windows versions for installation.

# Dropdown: title shown in UI, value stored internally
envs:
  - envName: VERSION
    options:
      - title: "Windows 11 Pro"
        value: "iso/Win11_24H2_English_x64.iso"
      - title: "Windows 7 Ultimate"
        value: "iso/win7_sp1_x64_1.iso"

remoteOptions

Loads the options list from a URL instead of defining it inline. The response body must be a JSON-encoded array in the same format as options.

Example: options fetched from a remote endpoint.

# Options list fetched from remote URL at install time
envs:
  - envName: VERSION
    remoteOptions: https://app.cdn.olares.com/appstore/windows/version_options.json
