Prerequisites for installing the server software on Ubuntu

You must complete certain tasks before you install HCL OneTest™ Server on the Ubuntu platform.

The following sections describe each prerequisite in detail:

Internet access

You must have access to the internet to install HCL OneTest™ Server.

Ubuntu Server

You must install supported version of Ubuntu Server and have a working Domain Name Server (DNS) that resolves the host name into a machine-readable IP address.

For more information about specific versions of software requirements, see System Requirements.

Note: Depending on your testing workload, HCL OneTest™ Server might require more resources. You must use the entire disk space and set up Logical Volume Manager (LVM) by using the ext4 file system. If your organization requires user data to be stored in a separate partition, then you can create a mount point at /var/lib/rancher/k3s/storage/ with at least 128 GB capacity.

Backup of user data

If you want to upgrade HCL OneTest™ Server from a previous version, then you must perform one of the following tasks based on the existing version of the server software:

  • Back up the data from V10.0.2, Fix Pack 1 or earlier. See Backing up the user data from a previous release.

  • Back up the data from V10.1.0 or later. See Backing up the server data on Ubuntu.
    Note: You must select the existing version of HCL OneTest™ Server from the drop-down list to view the procedure for backing up and restoring the user data for your version because the instructions differ for different versions.

Mandatory software

You must install the following mandatory software:

  • Helm. For more information, refer to the Helm documentation. For more information about specific versions of software requirements, see System Requirements.
    Note: The Helm command must be in one of the directories in your PATH environment variable.

  • OpenSSH Server. For more information, refer to the Installation section in the OpenSSH Server documentation.

    Note: If you use ssh to log in to the computer, then you can skip this step because OpenSSH is already installed on your computer.

k3s environment

You must set up the Kubernetes environment (k3s) along with other configurations such as firewall, Jaeger, and Prometheus server. See Setting up a Kubernetes environment (k3s) on Ubuntu.

Collection of usage metrics

If you want HCL OneTest™ Server to display the usage statistics of the virtual service instances, you must install the Prometheus server at the time of server installation.
