Install Juniper BNG CUPS

Use the procedures in this section to install Juniper BNG CUPS Controller in a single geography setup for the first time.

1. Download the Juniper BNG CUPS software package from Juniper Networks software download page, and save it to the jump host.

   BNG CUPS Controller is available as a compressed TAR file image (.tgz). The filename includes the release number as part of the name. The release number has the format:m.nZb.s

   For example, the software release number 23.4R1.5 maps to the following format:

   • m is the main release number of the product (for example, 23).

   • n is the minor release number of the product (for example, 4).

   • Z is the type of software release (for example, R for FRS or maintenance release).

   • b is the build number of the product (for example, 1, indicating the FRS release, rather than a maintenance release).

   • s is the spin number of the product (for example, 5).

2. Unpack the BNG CUPS Controller TAR file (.tgz) file on the jump host by entering:
3. Run the loader script after you unpack the TAR file.
4. Use the sudo -E dbng link --context context-name --version software-release command to link to the cluster. The link command associates the loaded BNG CUPS Controller software package to the cluster in preparation for the setup.

   • context context-name—The Kubernetes context name.

   • version software-release—The BNG CUPS Controller software version, as displayed from the dbng_loader output.

5. If you are installing BNG CUPS Controller on a Red Hat OpenShift Container Platform cluster, log in with the OpenShift CLI as a user with admin privileges and then proceed to the next step.
   If you are installing BNG CUPS Controller on a BBE Cloudsetup created cluster, proceed to the next step.
6. You must authenticate with the container registry in order to be able to push the BNG CUPS Controller container images. How you authenticate to the registry varies depending on if you are installing BNG CUPS Controller on a BBE Cloudsetup created cluster or on a Red Hat OpenShift Container Platform cluster (see the respective documentation for details).

   If you are using a secure registry (created on a BBE Cloudsetup created cluster), you authenticate with the registry by issuing a docker login as the system user (the system user supplied in the BBE Cloudsetup configuration file) to the cluster's registry transport address (the FQDN supplied as the system address in the BBE Cloudsetup configuration file).

7. Run setup to configure your installation. The setup command does the following:

   • Establishes the operational parameters for the Kubernetes deployment.

     If you did not use either the bbecloudsetup option or the template file-name option with the setup command, you need to complete these prompts during the setup:

     • If you are using BBE Cloudsetup to create your cluster:

       • External registry address.

       • External registry port number.

     • If you are using a Red Hat OpenShift Container Platform cluster:

       • External registry (fully qualified domain name)

       • Internal (Docker) registry address

       • Internal (Docker) registry port number

   Note:

   context context-name is the only required option for the setup command.

   The options that you can use with the setup command are listed in the following:

   • context context-name—The Kubernetes context name.

   • h, help—Shows the help message and exit.

   • l, log [error, warning, info, debug]—Adjusts the log level.

   • no-color—Prints messages without colors.

   • bbecloudsetup—Fills in operational parameters that align with a bbecloudsetup created cluster so that you do not have to interact with BNG CUPS Controller during the setup process (see the BBE Cloudsetup Installation Guide for cluster installation instructions).

     Note:

     Only use either the bbecloudsetup option or the template file-name option. Do not use both options.

   • update—You will only be prompted for missing values during setup.

   • ssh host:port—A hostname or IP address of the cluster (any of the cluster’s nodes) and open port used for SSH access to the CLI.

   • secrets—Updates the keys, certificates, and secrets used by the BNG CUPS Controller.

   • verbose—Provides a detailed description before each prompted question.

   • config file-name—The name of the initial configuration file that you want BNG CUPS Controller to use during startup.

   • template file-name—A YAML formatted file that contains a subset of the configuration file that is created during setup. The values that are entered in the template file are used automatically by the setup process. When you use the template option, you are not required to manually enter the information contained in the template file during the setup process. You should only use the template option when using Red Hat OpenShift Container Platform to create the cluster or when creating a multiple geographical cluster. Table 3 describes the information that you need to enter into the template configuration file.

     Note:

     Only use either the bbecloudsetup option or the template file-name option. Do not use both options.

   • mandatory—Only asks required questions during setup.

   • optional—Only asks questions that are not required during setup.

8. Verify the BNG CUPS Controller installation by running the dbng-version command.

   • context context-name—The Kubernetes context name.

   • detail—Displays all available software versions.

Use this procedure to configure and to start BNG CUPS Controller in a single geography setup.

1. Enter rollout to start the BNG CUPS Controller installation. The BNG CUPS Controller utility allows you to roll out different software versions for all microservices that are part of BNG CUPS Controllerted. You need to use the rollout command with sudo as root. The rollout command also validates that all the values needed for the new release are present and loads the new release container images to the registry. Use sudo -E dbng rollout --context context-name --version software-release --service service-name to start BNG CUPS Controller services. For example:

   • context-name—The Kubernetes context.

   • service service-name—The microservice name to rollout (for example, scache or cpi).

   • version software-release—The software release to rollout (defaults to the release that links to the cluster).

   Note:

   On the, first rollout -–service is not required. The -–service is used with the –-version to rollout (upgrade) specific versions of specific services.

   Note:

   By default, BNG CUPS Controller starts from factory-default. The configuration is reset to its initial state. Any persistent state and any persistent logs are cleared.

2. Enter dbng status --context context-name --detail to verify that the BNG CUPS Controller services are up and running. For example:
   Note:

   Collect the logs for a service and contact the Juniper Networks Technical Assistance Center (JTAC) when either of the following occurs:

   • The service is not running.

   • The service’s up time compared with other services indicates that it has restarted.

3. You must add a control plane instance (CPi) to your BNG CUPS Controller. Run the CPi add command.

   • context-name—The Kubernetes context name.

   • version software-release—The software release for the new CPi pod. Enter a release.

   • cpi-label—The label is used to uniquely name the CPi for identification purposes. In the above example output the cpi-label is cpi-example-1.

4. Verify that the CPi microservice is running, by using the dbng status command.

   • context-name—The Kubernetes context name.

   • detail—Displays detailed information.

Use the installation procedures in this section for a BNG CUPS Controller setup that consists of multiple BNG CUPS Controllers that are located in different geographical locations.

1. Create the jnpr-bng-controller namespace/project in the management context.

   • context management-context-name—The context name for the management cluster. Be aware that this context is not the same as the Karmada context name that is associated with the management cluster.

2. Create the karmada-kconf secret. Create the secret on the management cluster in the BNG CUPS Controller namespace using the management cluster’s kubeconfig.
   Note:

   The karmada-kconf secret contains the kubeconfig that is used by the observer to monitor the status of the CPi. If the secret is not created, the observer (and the BNG CUPS Controller) will not operate correctly.

   Run the following command:

   • management-context-name—The context name for the management cluster. Be aware that this context is not the same as the Karmada context name that is associated with the management cluster.

   • karmada-secret-file—The management cluster’s kubeconfig file.

3. Verify that the secret is created by running the following command:
   Note:

   Depending on your setup, the number of bytes listed may very.

4. Download the Juniper BNG CUPS software package from Juniper Networks software download page, and save it to the jump host.

   BNG CUPS Controller is available as a compressed TAR file image (.tgz). The filename includes the release number as part of the name. The release number has the format:m.nZb.s

   For example, the software release number 23.4R1.5 maps to the following format:

   • m is the main release number of the product (for example, 23).

   • n is the minor release number of the product (for example, 4).

   • Z is the type of software release (for example, R for FRS or maintenance release).

   • b is the build number of the product (for example, 1, indicating the FRS release, rather than a maintenance release).

   • s is the spin number of the product (for example, 5).

5. Unpack the BNG CUPS Controller TAR (.tgz) file on the jump host by entering:
6. Run the loader script after you unpack the TAR file.
7. Use the sudo -E dbng link command to link to the cluster. In preparation for running setup, the link command takes the list of workload cluster contexts and an observer context and associates them to the loaded BNG CUPS Controller software package,

   • context karmada-context-name—The context name of the Karmada context that is created when Karmada is installed on the management cluster.

   • worload-contexts workload-1-context-name workload-2-context-name—The two workload context names.

   • observer-context management-context-name—The context name for the management cluster. Be aware that this context is not the same as the Karmada context name that is associated with the management cluster.

   • version software-release—The BNG CUPS Controller software version, as displayed from the dbng_loader output.

   Note:

   During installation, Karmada is installed on the management cluster and Karmada creates its own context on the management cluster. The Karmada context is used to target any operations involving the workload clusters. The management cluster also has its own context that is used for running noncritical centralized workloads (for example, BBE Event Collection and Visualization). You use this management cluster context for the observer-context.

   Figure 1 shows where the different contexts are located in a multiple cluster setup.

   Figure 1: Multiple Cluster Contexts
8. When using a RHOCP cluster, you can interact with it after authenticating the OpenShift cluster and the three RHOCP clusters (management and two workload clusters) using the OpenShift CLI.

   For an example of the command to run, see the following:

9. In order to push the BNG CUPS Controller container images, you must authenticate with the registry on each cluster in the multiple cluster setup. You authenticate with the registry by issuing a docker login as the system user (the system user entered in the BBE Cloudsetup configuration file) to the cluster's registry transport address (the FQDN supplied as the system address in the BBE Cloudsetup configuration file).
10. Run setup to configure your installation. The setup command does the following:

    • Collects information about the cluster environment—The information collected consists of the following:

      • Names of storage classes or persistent volumes

      • Location of a container registry

      • Container and pod name of registry

      • TLS keys

      • Information relevant to supporting BNG CUPS Controller features.

    • Initializes the BNG CUPS Controller configuration.

    During the setup process you will be prompted for information. To avoid entering information during the setup process, you can use a template file (for a description of the template file, see template).

    If you did not use a template file, the following prompts may appear during the setup process:

    • The following information for the observer on the management cluster:

      • External registry address and port number for each cluster. Click the Enter key after entering the information for each cluster.
