A web application for viewing the status of HPC resources in a browser based dashboard.

Deployment Overview

This application is deployed in a Kubernetes environment called the CIRRUS cloud.
Deployment is managed using a Helm chart, which resides in a separate repository:

NCAR/sage-data-commons-dashboard-k8s-dev

---

Deployment Steps

When code changes are pushed to this repository, GitHub Actions automatically build and publish a Docker image to the repository’s container registry:

GitHub Packages – sage-data-commons-dashboard

1. Identify the New Artifact Tag

After a successful build, locate the latest image tag, for example:

0.0.1-SNAPSHOT-20251007-141304

2. Update the Helm Chart

Copy the desired image tag and update the values.yaml file in the Helm chart repository:

yaml container: tag: 0.0.1-SNAPSHOT-20251007-141304

Trigger ArgoCD Deployment

Once the values.yaml file is updated and committed:

• ArgoCD detects the change automatically.
• It then deploys the new image to the CIRRUS Kubernetes environment.

Note:
The Helm chart repository is private.
Authentication is handled via an SSH Deploy Key pair configured in the ArgoCD application and the repo.
