System-injected runtime values

At deployment, Olares automatically injects a set of system-managed values into the app's values.yaml. These values are read-only and cover user identity, storage paths, cluster metadata, app dependencies, and middleware credentials.

Because they are Helm values, they are not automatically available inside containers. To pass one into a container, map it explicitly under env: in your deployment template.

Use in your app

Reference these values directly in your Helm templates, such as deployment.yaml.

Example: pass the current username and Postgres host into container environment variables.

# Pass system-injected runtime values into container environment variables
spec:
  containers:
    - name: my-app
      env:
        - name: APP_USER
          value: "{{ .Values.bfl.username }}"
        - name: DB_HOST
          value: "{{ .Values.postgres.host }}"

For the full list of available values, see Value reference.

Value references

The Type column describes the Helm value data type. It does not correspond to the type field in OlaresManifest.yaml.

User and identity

Value	Type	Description
.Values.bfl.username	String	Current username.
.Values.user.zone	String	Current user's domain.
.Values.admin	String	Administrator username.

Application and system information

Value	Type	Description
.Values.domain	Map<String,String>	App entrance URLs. Each entry maps an entrance name to its URL.
.Values.sysVersion	String	Current Olares system version.
.Values.deviceName	String	Device name.
.Values.downloadCdnURL	String	CDN address used for system resource downloads.

Storage paths

Value	Type	Description
.Values.userspace.appData	String	Cluster storage path for the app. Path: /Data/<appname>.
.Values.userspace.appCache	String	Node-local cache path for the app. Path: /Cache/<appname>.
.Values.userspace.userData	String	User's home data directory. Path: /Files/Home/.
.Values.sharedlib	String	User's external storage directory. Path: /Files/External/<devicename>/.

Cluster hardware metadata

Value	Type	Description
.Values.cluster.arch	String	Cluster CPU architecture, such as amd64. Mixed-architecture clusters are not supported.
.Values.nodes	List<NodeInfo>	Hardware metadata for each node in the cluster.

Each entry in .Values.nodes follows this structure:

// Single entry in the .Values.nodes list
[
  {
    "cudaVersion": "12.9",
    "cpu": [
      {
        "coreNumber": 16,
        "arch": "amd64",
        "frequency": 4900000000,
        "model": "151",
        "modelName": "12th Gen Intel(R) Core(TM) i5-12600KF",
        "vendor": "GenuineIntel"
      }
    ],
    "memory": {
      "total": 50351353856
    },
    "gpus": [
      {
        "vendor": "NVIDIA",
        "arch": "Ada Lovelace",
        "model": "4060",
        "memory": 17175674880,
        "modelName": "NVIDIA GeForce RTX 4060 Ti"
      }
    ]
  }
]

Application dependencies

When an app declares a dependency in OlaresManifest.yaml, Olares injects connection information into values.yaml.

Value	Type	Description
.Values.deps	Map<String,Value>	Main entry host and port for each declared dependency. Keys follow the pattern <entry_name>_host and <entry_name>_port.
.Values.svcs	Map<String,Value>	All service hosts and ports for each declared dependency. Keys follow the pattern <service_name>_host and <service_name>_port. Port values are lists to support multiple ports per service.

Example: for a dependency with entry name aserver and service name aserver-svc.

.Values.deps:

{
  "aserver_host": "aserver-svc.<namespace>",
  "aserver_port": 80
}

.Values.svcs:

{
  "aserver-svc_host": "aserver-svc.<namespace>",
  "aserver-svc_port": [80]
}

Middleware values

Middleware values are injected only after you declare the middleware dependency in the middleware section of OlaresManifest.yaml.

PostgreSQL and Redis are preinstalled. MongoDB, MinIO, RabbitMQ, MySQL and MariaDB must be installed separately before your app can use them.
