Install and Verify Juniper Cloud-Native Router for OpenShift Deployment

The Juniper Cloud-Native Router (cloud-native router) uses the the JCNR-Controller (cRPD) to provide control plane capabilities and JCNR-CNI to provide a container network interface. Juniper Cloud-Native Router uses the DPDK-enabled vRouter to provide high-performance data plane capabilities and Syslog-NG to provide notification functions. This section explains how you can install these components of the Cloud-Native Router on Red Hat OpenShift Container Platform (OCP).

Install Juniper Cloud-Native Router Using Helm Chart

Read this section to learn the steps required to install the cloud-native router components using Helm charts.

  1. Review the System Requirements for OpenShift Deployment to ensure the cluster has all the required configuration.
  2. Download the desired Cloud-Native Router software package to the directory of your choice.
    You have the option of downloading the package to install Cloud-Native Router only or downloading the package to install JNCR together with Juniper cSRX. See Cloud-Native Router Software Download Packages for a description of the packages available. If you don't want to install Juniper cSRX now, you can always choose to install Juniper cSRX on your working Cloud-Native Router installation later.
  3. Expand the file Juniper_Cloud_Native_Router_release-number.tgz.
  4. Change directory to the main installation directory.

    • If you're installing Cloud-Native Router only, then:

      This directory contains the Helm chart for Cloud-Native Router only.

    • If you're installing Cloud-Native Router and cSRX at the same time, then:

      This directory contains the combination Helm chart for Cloud-Native Router and cSRX.
    Note:

    All remaining steps in the installation assume that your current working directory is now either Juniper_Cloud_Native_Router_<release> or Juniper_Cloud_Native_Router_CSRX_<release>.
  5. View the contents in the current directory.
  6. Change to the helmchart directory and expand the Helm chart.

    • For Cloud-Native Router only:

      The Helm chart is located in the jcnr directory.

    • For the combined Cloud-Native Router and cSRX:

      The Helm chart is located in the jcnr_csrx directory.
  7. The Cloud-Native Router container images are required for deployment. Choose one of the following options:

    • Configure your cluster to deploy images from the Juniper Networks enterprise-hub.juniper.net repository. See Configure Repository Credentials for instructions on how to configure repository credentials in the deployment Helm chart.

    • Configure your cluster to deploy images from the images tarball included in the downloaded Cloud-Native Router software package. See Deploy Prepackaged Images for instructions on how to import images to the local container runtime.

  8. Follow the steps in Installing Your License to install your Cloud-Native Router license.
  9. Enter the root password for your host server into the secrets/jcnr-secrets.yaml file at the following line:
    You must enter the password in base64-encoded format. To encode the password, create a file with the plain text password on a single line. Then issue the command: Copy the output of this command into secrets/jcnr-secrets.yaml.
  10. Apply secrets/jcnr-secrets.yaml to the cluster.
  11. If desired, configure how cores are assigned to the vRouter DPDK containers. See Allocate CPUs to the Cloud-Native Router Forwarding Plane.
  12. Customize the Helm chart for your deployment using the helmchart/jcnr/values.yaml or helmchart/jcnr_csrx/values.yaml file.

    See Customize Cloud-Native Router Helm Chart for OpenShift Deployment for descriptions of the Helm chart configurations.

  13. Optionally, customize Cloud-Native Router configuration.
    See Customize Cloud-Native Router Configuration for creating and applying the cRPD customizations.
  14. If you're installing Juniper cSRX now, then follow the procedure in Apply the cSRX License and Configure cSRX.
  15. Deploy the Juniper Cloud-Native Router using the Helm chart.
    Navigate to the helmchart/jcnr or the helmchart/jcnr_csrx directory and run the following command:or
  16. Confirm Juniper Cloud-Native Router deployment.

    Sample output:

Verify Installation

This section enables you to confirm a successful Cloud-Native Router deployment.
Note:

The output shown in this example procedure is affected by the number of nodes in the cluster. The output you see in your setup may differ in that regard.
  1. Verify the state of the Cloud-Native Router pods by issuing the kubectl get pods -A command.
    The output of the kubectl command shows all of the pods in the Kubernetes cluster in all namespaces. Successful deployment means that all pods are in the running state. In this example we have marked the Juniper Cloud-Native Router Pods in bold. For example:
  2. Verify the Cloud-Native Router daemonsets by issuing the kubectl get ds -A command.

    Use the kubectl get ds -A command to get a list of daemonsets. The Cloud-Native Router daemonsets are highlighted in bold text.

  3. Verify the Cloud-Native Router statefulsets by issuing the kubectl get statefulsets -A command.

    The command output provides the statefulsets.

  4. Verify if the cRPD is licensed and has the appropriate configurations
    1. View the access the cRPD CLI section to access the cRPD CLI.
    2. Once you have access the cRPD CLI, issue the show system license command in the cli mode to view the system licenses. For example:
    3. Issue the show configuration | display set command in the cli mode to view the cRPD default and custom configuration. The output will be based on the custom configuration and the Cloud-Native Router deployment mode.
    4. Type the exit command to exit from the pod shell.
  5. Verify the vRouter interfaces configuration
    1. View the access the vRouter CLI section to access the vRouter CLI.
    2. Once you have accessed the vRouter CLI, issue the vif --list command to view the vRouter interfaces . The output will depend upon the Cloud-Native Router deployment mode and configuration. An example for L3 mode deployment, with two fabric interfaces configured, is provided below:
    3. Type the exit command to exit the pod shell.
