At this point all of the participants should be able to run any of the following binaries locally: Packer, Terraform, Consul, Consul-Template, Nomad, Vault, Docker. The project should encompass a full blown cloud environment configured and orchestrated with the Hashicorp stack. Final project should have the following points covered:

• Packer images uploaded in a private cloud environment (for example OpenStack, OpenNebula, CloudStack etc)
• Infrastructure defined as code in a couple of git repos
• All the actions automated using Gitlab Pipelines
• VMs created with Terraform in the cloud environment
• A high-available cluster for Nomad, Consul and Vault
• Docker images deployed and orchestrated with Nomad
• Health checks for the docker images which are available in Consul
• Applications talking via SSL with certificates generated by consul-template from Vault which self-renew
