Handlers

These are the handlers that are defined in handlers/main.yml.

restart tendermint

Example playbook that configures a Tendermint on Ubuntu

---

- 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 there are no validators in genesis file. See templates/genesis.json.j2.

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 add them to templates/genesis.json.j2:

{
  "app_hash": "",
  "chain_id": "{{tendermint_chain_id}}",
  "genesis_time": "{{tendermint_genesis_time}}",
  "validators": [
    {
      "pub_key": [1, "3A4B5F5C34B19E5DBD2DC68E7D6FF7F46859A0657EDCA3274235A7EB127A0706"],
      "amount": 10,
      "name": "1"
    }
  ]
}
