How to use this repository

1. Clone the repository onto the machine you'll use to deploy the software to the server
2. Install Ansible
3. Use Ansible Galaxy to install the following roles:
   • Datadog
   • Traefik
   • Docker
   • Vault
   • Nomad
   • Consul
     • Optionally run ansible-galaxy install --roles-path ./ansible/roles -r requirements.yml from the project's root directory.
4. Update inventory/hosts and set the target IP Address to the ip address you are using for your server
5. Update plays/home_server.yml and set the following4

   • All variables ending in _domain must be set to the same value

     This is the domain that you will use to look up services on your network. It defaults to consul

   • consul_recursors - The DNS servers you want to use for external lookups, we use the Google ones by default.

   • nomad_vault_address - Whilst we set this up, we won't have DNS running, so we need to hard-code the IP Address for the Vault server here.

6. Overwrite ansible/roles/kibatic.traefik/templates/traefik.toml with the file at custom_configuration_files/traefik.toml.j2 in this repository
7. Follow the instructions on the blog post to create a Vault token for Nomad
8. Create two encrypted files using Ansible vault in the following locations (replacing the dummy values with the actual text):
   • inventory/group_vars/all containing datadog_api_key: "My DataDog API Key"
   • inventory/group_vars/docker_instances containing nomad_vault_token: "My Vault Nomad Token"
9. Execute Ansible against the playbook in plays
