Estimate hardware capacity needs

A VM or server with the following specifications:

• 16 x CPU cores (x86_64 processor with speed of 2.2 GHz or more). The CPU must support the instructions SSE4.1 SSE4.2 AVX AVX2 FMA

• 64GB RAM

• 700GB Free SSD disk. K3s will be installed in /var/lib/rancher so space should be allocated there. We also need 10-20 GB free space at / and /var.

• Ubuntu 20.04 LTS Server OS is recommended. RHEL 8.6, 8.7, 8.8, & 9.2, and Suse Linux 15.3 are also supported but may need extra configuration.

• Port 443/TCP open

• Outbound internet access to download application artefacts. 100 Mbps download speed recommended

• Domain Name Service (DNS) with public name resolution enabled

• Network Time Protocol (NTP)

• Software Update Service - access to a network-based repository for software update packages.
