Air-Gap Install Paragon Automation on Ubuntu

You can install and deploy a paragon Automation cluster using the air-gap method of installation. In the air-gap method you need not have Internet access on the cluster nodes. You need a control host to download the distribution software and then create and configure the installation files to run the installation from the control host. You must be able to use SSH to connect to all the nodes.

To use the air-gap method install Paragon Automation on nodes with Ubuntu as the base OS, perform the following steps.
  1. Prepare the control host for the installation process as described in Prepare the Control Host.
  2. Prepare the cluster nodes for the installation process as described in Prepare Cluster Nodes.
    Note:

    You must ensure that the following packages are installed on the cluster nodes else air-gap installation will fail:

    apt-transport-https, ca-certificates, curl, docker.io, jq, keepalived

    If you want to use Chrony, you must pre-install Chrony. The installer does not install Chrony during air-gap installations.
  3. Ensure you have the required VIP addresses as described in Virtual IP Address Considerations.
  4. Log in to the control host node.
  5. Download the Paragon Automation Setup installation folder to a download directory and extract the folder. You can use the wget "http://cdn.juniper.net/software/file-download-url" command to download the folder and any extraction utility to extract the files.

    You need a Juniper account to download the Paragon Automation software.

  6. Follow steps 1 through 7 of the installation process as described in Install Multinode Cluster on Ubuntu.
  7. Install the Paragon Automation cluster based on the information that you configured in the config.yml and inventory files.

    The installation time to install the configured cluster depends on the complexity of the cluster. A basic setup installation takes at least 45 minutes to complete.

    NTP synchronization is checked at the start of deployment. If clocks are out of sync, deployment fails.

  8. When deployment is completed, log in to the worker nodes.

    Use a text editor to configure the soft and hard memory limits for influx DB memory requirements for Paragon Insights in the limits.conf and sysctl.conf files.

    Repeat this step for all worker nodes.

  9. Follow the steps described in Log in to the Paragon Automation UI to access the GUI.
