Example playbook that configures a Tendermint on Ubuntu 14.04

---

- hosts: all
  vars:
    tendermint_chain_id: MyAwesomeChain
    tendermint_seeds: "172.13.0.1:46656,172.13.0.2:46656,172.13.0.3:46656"
  roles:
    - ansible-tendermint

This playbook will install Tendermint and will create all the required directories. But it won't start the Tendermint if no validators were given.

You will need to collect validators public keys manually or using collect_public_keys.yml given you have SSH access to all the nodes and set tendermint_validators variable:

---

- hosts: all
  vars:
    tendermint_chain_id: MyAwesomeChain
    tendermint_seeds: "172.13.0.1:46656,172.13.0.2:46656,172.13.0.3:46656"
    tendermint_validators:
      - pub_key:
          - 1
          - 1F017E488A6327FAFBBE092193B427912E117733DE6AF72150BF09AA58411E7F
        amount: 10
