You can view all added artifacts or DAG components.

​
Prerequisite

Before starting this task, ensure you have the nx1_app_manager role, or a role previously assigned to this specific app using Create an app-to-role mapping.

​
View a component

Perform these steps to view a component in the portal:
  1. Log in to NexusOne.
  2. On the top navigation bar, hover your mouse over Platform, and then select App Manager.
  3. Select Mine if you want to view a component from your own app, or Everyone if you want to view a component from someone else’s app.
  4. In the table, scroll down, and then select an app you want to view a component from.
  5. On the Versions tab, select the app version that has the component.
  6. In the file table, view the component files, along with their types and sizes.

​
View a component in object storage

When you purchase NexusOne, the NexusOne team configures and notifies you about a default S3 bucket where you can find all uploaded artifacts or DAG components. This task doesn’t need a specific role. Any logged-in NexusOne user can launch JupyterHub and browse their own S3 credential. Perform these steps to view a component in object storage:
  1. Log in to NexusOne.
  2. Launch a JupyterHub environment
  3. Click the object storage browser for S3 icon.
  4. In the S3 bucket, browse to the component you want to view:
    • For an active app version, you can find the components in the following paths:
      • Artifacts: <bucket_name>/deps/<app_name>/current/
      • DAGs: <bucket_name>/deps/<app_name>/current/dags/
    • For all versions of an app, including the active version, you can find the components in the following paths:
      • Artifacts: <bucket_name>/deps/<app_name>/<version_name>/
      • DAGs: <bucket_name>/deps/<app_name>/<version_name>/dags/
  5. Optional: If you change the status of another app version to Active, then the components of the new active app version replace components of the previously activated app version in the /current/ path. However, you have to do one of the following to see the new components in the /current/ path:
    • Use the s3Cli ls command to see the new changes.
    • Restart the JupyterHub server by navigating to File > Hub Control Panel > Stop My Server > Start My Server > Start. Then browse to the component you want to view.
