Before you use this template

We strongly believe that infrastructure code should be obvious and majority of information should be hard-coded. Hence this example contains even domain names and firewall rules with hard-coded parameters. If you want to use this code for your own PoC, please replace following stuff with information specific for your environment:

• terraform/consul/droplets.tf: reference to packer image
• terraform/nomad-server/droplets.tf: reference to packer image
• terraform/nomad-client/droplets.tf: reference to packer image
• terraform/consul/dns.tf: DNS records for droplets
• terraform/nomad-server/dns.tf: DNS records for droplets
• terraform/nomad-client/dns.tf: DNS records for droplets
• terraform/consul/data.tf: DNS records for droplets
• terraform/nomad-server/data.tf: DNS records for droplets
• terraform/nomad-client/data.tf: DNS records for droplets
• terraform/firewall/*: adjust firewall according to your needs
• terraform/loadbalancer/dns.tf: DNS records for Nomad services
• terraform/loadbalancer/certificate.tf: Let's Encrypt certificate for Nomad services
