Overall Architecture

Platform Architecture

This blueprint is expected to run on multiple environments (libvirt, AWS and baremetal).

Deployments to AWS

nodesinstance type
1x bootstrap (temporary)EC2: m4.xlarge, EBS: 120GB GP2
3x mastersEC2: m4.xlarge, EBS: 120GB GP2
3x workersEC2: m4.large, EBS: 120GB GP2

Deployments to Bare Metal

nodesrequirements
1x provisioning host (temporary)12 cores, 16GB RAM, 200GB disk free, 3 NICs (1 internet connectivity, 1 provisioning+storage, 1 cluster)
3x masters12 cores, 16GB RAM, 200GB disk free, 2 NICs (1 provisioning+storage, 1 cluster)
3x workers12 cores, min. 16GB RAM, 200GB disk free, 2 SR/IOV-capable NICs (1 provisioning+storage, 1 cluster)


The blueprint validation lab uses 7 SuperMicro SuperServer 1028R-WTR (Black) with the following specs:
