Example playbook that configures a Tendermint on Ubuntu

---

- hosts: all
  vars:
    tendermint_chain_id: MyAwesomeChain
  roles:
    - ansible-tendermint

This playbook will install Tendermint and will create all the required directories. But it won't start the Tendermint if there are no validators in genesis file. See templates/genesis.json.j2.

You will need to collect validators public keys manually or using genesis.yml given you have SSH access to all the nodes.

Testing

vagrant up
