Ephemeral Apps with Chef, Terraform, Nomad, and Habitat

on YouTube ↗41m

" summary

A tiny Go HTTP-echo app gets packaged with Habitat (plan, default.toml, run hook), updated to handle graceful shutdown on SIGTERM, and exported to Docker. Terraform provisions a Nomad/Consul cluster; Nomad schedules the Habitat supervisor and hundreds of dynamic-port backends while Consul provides DNS service discovery. An Nginx Habitat service does dynamic upstreams, and the demo scales to 50 then 200 instances in about a second, behind host-local port-80 load balancers — the pipeline is built and it works end-to-end.
