System requirements

Make sure that the target computer where you plan to install VSatellite meets the minimum requirements detailed below.

Operating systems

VSatellite is expected to work on most modern Linux systems (x86_64). However, please review the following:


Supported means fully tested by QA during the development life cycle. If issues or defects do arise, they'll be resolved by Venafi.

Supported operating systems include the following:

  • Ubuntu LTS 18.04 or later (x86_64)
  • Red Hat Enterprise Linux (RHEL) 7.9, 8.x and 9.x (x86_64)
  • Oracle Linux 8.x and 9.x (x86_64)
  • Rocky Linux 8.x and 9.x (x86_64)

RHEL, Oracle, and Rocky Linux installations

For RHEL, Oracle Linux, and Rocky Linux installations, review these special considerations.

Ensure that your selected operating system is updated with the latest patches. At a minimum, it must be able to retrieve updates from the operating system's standard software repository (for example, using apt-get or yum).

System resources

You can install VSatellites on either virtual computers (most common) or on physical hardware. In either case, your target computer must meet or exceed the following:

  • 4 GB RAM
  • 2 CPUs
  • 10 GB of free disk space

    IMPORTANT! Disk space requirements for VSatellite installation

    VSatellite uses specialized technology (Kubernetes K3s) and requires specific disk space allocations in the following folders:

    • /var/lib/rancher: ~85% of required space
    • /var/lib/kubelet: ~5% of required space
    • /usr/local/bin: ~5% of required space
    • /var/log/containers: ~3% of required space
    • /etc/rancher: ~2% of required space

    Custom Mount Points: If you have mounted any of the above folders to a different location, make sure to adjust the free disk space based on these percentages. For example, if you have /var/lib/rancher mounted on a separate disk at /mnt/mydisk/rancher, you would need to ensure that this location has enough space to accommodate ~85% of the required VSatellite disk space.

    Installation Warning: You may see a warning about free disk space during installation. This is normal and can be ignored, as the installer checks the root (/) mount point by default. Follow the space requirements listed above for a successful installation.
