TODO

  • Actually integrate vault

    • Vault-agent?
    • integrate with Nomad
    • integrate with Consul

  • REORG - put nomad, consul, and other roles into their own .tf files

  • missing CONSUL_COUNT template/config/bootstrap var (like NOMAD_COUNT?)

  • Add haproxy and replace traefik with it [apr 2022]

    • You can then access the API at port 5555. For example, in the demo project, http://192.168.50.20:5555/v2/docs will show you the API’s documentation.
    • is the dataplane API separate from the consul example that just uses DNS SRV records?

  • move nginx into container on nomad

    • it's a great demo of a single-host webserver using consul, though

  • use auto-scaling groups for consul, nomad, and traefik

  • use an ELB for traefik

  • BUG/incomplete: there is no way that /etc/nginx/sites-available/tutorialinux-python is working (in nginx/config/nginx-userdata.sh.tpl)

  • move python clients into containers

  • serve traffic on the public Internet

Demo Videos

  • service discovery demo

    • HTTP

  • consul DNS setup

    • DNS service discovery demo

  • load balancing demo

SMALL TODOs:

  • DNS is a little messed up - e.g. sudo -i takes really long because there's something that times out sudo: unable to resolve host ip-10-0-10-172: Name or service not known

  • set hostnames (for shell prompt and consul)

  • add node names in each config (set hostname?) (not a small TODO actually)

Nginx:

  • register nginx service with consul on startup (systemd unit file -- postexec?)
