The requirements for the Kubernetes cluster is a single node (1 virtual machine) with the following specs:
| Synergy | Focus | Enterprise (Synergy + Focus) |
|---|
CPU cores (x86_64 processor with speed of 2.2 GHz or more) | 8 | 16 | 20 |
RAM | 32GB | 64GB | 80GB |
Free SDD disk space | 500GB | 600GB | 700GB |
OS | We recommend Ubuntu 20.04.4 LTS Server (Focal Fossa), but you can also use RHEL 8.6, CentOS 7.9 or Suse Linux 15.3.
⚠️ If you are using CentOS or RHEL please refer to the official K3s documentation for additional setup. |
Firewall | The K3s server needs port 443/TCP to be open to allow the clients to access Synergy/Focus dashboard and API. Outbound internet access: In order to download the application artifacts (Docker images and binaries), updates and configuration files, the cluster needs a public internet connection with download speed of 40 Mbps or more and upload speed of 8 Mbps or more. To speed up the initial setup process it is recommended to have a download speed of 100 Mbps or more.
