3. ansible-playbook playbooks/03_consul.yml

7. ansible-playbook playbooks/05_nomad.yml
8. Run the aperture script to make sure everything is up and running: ./aperture.sh

Note that if you want to use any of the binary commands on the management station, be sure to source ~/.bashrc after each product installation, since this also sets the correct environment variables.

Bonus

There is a playbook included as a bonus that configures the Consul and Nomad secrets engine on Vault and enables an operator role for both of the secrets engines. This allows for reading dynamic Consul/Nomad ACL tokens.

1. ansible-playbook playbooks/10_bonus.yml
2. vault read consul/creds/operator
3. vault read nomad/creds/operator
