Rainbow deployments with Nomad
summary
Clover containerizes a legacy monolith on Nomad, uses Terraform and Packer to build immutable VM images, and deploys via Open Application Model + GitHub Actions into Nomad with an NGINX-style load balancer and Prometheus metrics. The demo runs three concurrent versions, performs a 50/50 traffic split between blue and green, and validates fixes by pinned-by-request-header routing (bbvd to blue, ccbd to red). Next steps: autoscale and promote old-version teardown.
