Celum runs as a self-contained appliance on your own hardware. One virtual machine carries Celum and everything it needs, with every container image already inside: Harbor, Authentik, OpenBao, PowerDNS and Omni.

4

Take the first steps

Check the appliance, trust its CA and sign in to Celum: First steps after the deploy.

​
Request the trial

Open the trial form on celum.io. The Start the trial button on the pricing page leads to it as well. Tick the box that lets Nuvira contact you about the request, and choose Request a walkthrough. We reply to set the trial up with you and walk you through Celum on your own infrastructure.
To see Celum before you install it, ask for a demo with the same form. Prefer email? Write to contact@nuvira.dev.

​
What you receive

  • The appliance image, in the format for your platform:
    • OVA, for VMware vSphere: celum-appliance-VERSION.ova;
    • qcow2, for KVM hypervisors such as Proxmox VE and libvirt: celum-appliance-VERSION.qcow2.
    The email that brings it also gives each file’s SHA-256 checksum. Check the download against it before you import it; the deploy guides show how.
  • An update account with your licence: a robot account and its secret for registry.celum.io. The appliance uses it to install new Celum releases. You can enter it at deployment, or later on the start page.

​
Prepare while you wait

  • A hypervisor: vSphere 7.0 or later, or Proxmox VE or libvirt/KVM.
  • Resources: 8 vCPU, 16 GB of RAM and a 120 GB disk.
  • A static IPv4 address, with its gateway and your DNS servers.
  • A domain for the appliance, for example celum.example.com, with every name it serves resolving to its address. A wildcard record such as *.celum.example.com covers them all.
  • An SSH public key for root.
The deploy guides list the details, including the ports to open.

​
After the trial

Before the 30 days are over, contact us and we size a subscription against your estate. It is priced per node, per year. Whatever you decide, the clusters you built keep running: they are standard Cluster API objects on your own hardware.

​
Next steps

Deploy on vSphere (OVA)

Import the OVA into vCenter and configure it in the deploy wizard.

Deploy on KVM (qcow2)

Run the qcow2 on Proxmox VE or libvirt, configured with cloud-init.
