Creating an application version#

We now need to create an application-version.yaml file to specify the details of the version of the Omniverse Kit App we want to deploy, including the container image, version, and related metadata.

Creating an application version#

Create a new file called application-version.yaml.
In the file, specify the Kind as ApplicationVersion.
Sample application-version.yaml for version 0.2.0 of the usd-viewer application#
```
apiVersion: omniverse.nvidia.com/v1
kind: ApplicationVersion
metadata:
  name: usd-viewer-0.2.0
  labels:
    app: usd-viewer
    applicationName: usd-viewer
    version: '0.2.0'
spec:
  helm_chart: ngc-omniverse/kit-appstream-session
  helm_chart_version: '1.4.0'
  container: nvcr.io/nvidia/omniverse/usd-viewer
  container_version: '0.2.0'
```
2.1 Specify the ApplicationVersion ID and semantic version of the application:

metadata.name:

The ApplicationVersion ID

metadata.labels.version:

The semantic version of the application.

2.2 We use metadata from the Application to link the version to it:

metadata.labels.app:

Application.metadata.name

metadata.labels.applicationName:

Application.spec.name

2.3 The spec section is where you define the container image and version for the Kit App:

spec.container:

Container image to use

spec.container_version:

Version of the container image to use

2.4 That is also where you specify a Helm chart used to deploy it:

spec.helm_chart:

URL of the Helm chart to use

spec.helm_chart_version:

Version of the Helm chart to use

Install the application version using kubectl:

kubectl apply -f application-version.yaml -n omni-streaming

List the new application version:

kubectl describe applicationversions.omniverse.nvidia.com usd-viewer-0.2.0 -n omni-streaming

List the new application version by calling the APS endpoint:

curl http://<ingress url of the AP service>/cfg/apps/usd-viewer/versions
