Install and Verify Juniper Cloud-Native Router on Amazon EKS

The Juniper 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.

Install Juniper Cloud-Native Router Using Juniper Support Site Package

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

  1. Review the System Requirements for EKS Deployment to ensure the setup 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. Follow the steps in Installing Your License to install your Cloud-Native Router license.
  8. 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.
  9. Apply secrets/jcnr-secrets.yaml to the cluster.
  10. Create the JCNR ConfigMap if using the Virtual Router Redundancy Protocol (VRRP) for your Cloud-Native Router cluster. A sample jcnr-aws-config.yaml manifest is provided in cRPD_examples directory in the installation bundle. Apply the jcnr-aws-config.yaml to the Kubernetes system.
  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 JCNR Helm Chart for EKS Deployment for descriptions of the helm chart configurations and a sample helm chart for EKS deployment.

  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. Install Multus CNI using the following command:
  16. Install the Amazon Elastic Block Storage (EBS) Container Storage Interface (CSI) driver.
  17. Label the nodes where you want Cloud-Native Router to be installed based on the nodeaffinity configuration (if defined in the values.yaml). For example:
  18. 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
  19. Confirm Juniper Cloud-Native Router deployment.

Install Juniper Cloud-Native Router Using AWS Marketplace Subscription (BYOL)

Use this procedure to install JCNR (BYOL) from AWS Marketplace using Helm charts.

This procedure installs Cloud-Native Router on your existing Amazon EKS cluster. Ensure you've set up your Amazon EKS cluster prior to running this procedure. You can use any method to create an EKS cluster as long as it meets the system requirements described in System Requirements for EKS Deployment.

For convenience, we've provided a CloudFormation template that you can use to quickly get a cluster up and running. This template is provided in CloudFormation Template for EKS Cluster.

  1. Review the System Requirements for EKS Deployment to ensure the setup has all the required configuration.
  2. Log in to and search for Cloud-Native Router products from the AWS Marketplace.
  3. Select the JCNR (BYOL) product and subscribe to it.
  4. Scroll down on the selected product's landing page to view the usage instructions.

    The instructions show you how to log in to the ECR Helm registry and download the Cloud-Native Router helm chart.

  5. Copy and run the provided usage instructions on the setup where you issue your AWS CLI commands.
    This downloads the jcnr-<version>.tgz file onto your setup.
  6. Expand the file jcnr-<version>.tgz.
  7. Change directory to jcnr.
    Note:

    All remaining steps in the installation assume that your current working directory is now jcnr.
  8. View the contents in the current directory.
  9. Follow the steps in Installing Your License to install your Cloud-Native Router license.
  10. Enter the root password for your host server into the secrets/jcnr-secrets.yaml file at the following line:
