4. Getting started

This section provides the basic information you need to get started with Nubus on a Kubernetes cluster. With this information, you can sign in to the Nubus system and start using it.

To follow along, you first need to complete the steps in Deployment.

4.1. Provided users

The default Nubus installation provides the following user:

Administrator

This user has role the admin and user, which can manage the Nubus system and access all the available applications.

To get the different user passwords, use the following steps:

1. Set the environment variables by running the commands in Listing 3.5.

2. For the default administrator, use the command in Listing 4.1

   Listing 4.1 Get password for Administrator user

   $ kubectl -n  "$NAMESPACE_FOR_NUBUS" get secret nubus-nubus-credentials \
      -o json | jq -r '.data.administrator_password' | \
      base64 -d
   

4.2. Open the Portal

The Portal is the central entry point to Nubus for Kubernetes. Open your web browser and access the Portal under the following URL: https://portal.$(global.domain)/. The value in global.domain completes the FQDN of the URL.

Example:

https://portal.nubus.example.com/, where nubus.example.com is the value in global.domain.

4.3. Render Helm Chart template

To look up the final values of the configuration and to reference purposes of the Helm Chart used for your deployment, you can use Helm to render the template as shown in Listing 4.2.

Listing 4.2 Use Helm to render the Helm Chart template

$ helm template \
   --values custom_values.yaml \
   --version "$VERSION" \
