Deploy a Testnet ================ Now that we've seen how ABCI works, and even played with a few applications on a single validator node, it's time to deploy a test network to four validator nodes. Manual Deployments ------------------ It's relatively easy to setup a Tendermint cluster manually. The only requirements for a particular Tendermint node are a private key for the validator, stored as ``priv_validator.json``, a node key, stored as ``node_key.json`` and a list of the public keys of all validators, stored as ``genesis.json``. These files should be stored in ``~/.tendermint/config``, or wherever the ``$TMHOME`` variable might be set to. Here are the steps to setting up a testnet manually: 1) Provision nodes on your cloud provider of choice 2) Install Tendermint and the application of interest on all nodes 3) Generate a private key and a node key for each validator using ``tendermint init`` 4) Compile a list of public keys for each validator into a ``genesis.json`` file and replace the existing file with it. 5) Run ``tendermint node --proxy_app=kvstore --p2p.persistent_peers=< peer addresses >`` on each node, where ``< peer addresses >`` is a comma separated list of the IP:PORT combination for each node. The default port for Tendermint is ``46656``. Thus, if the IP addresses of your nodes were ``192.168.0.1, 192.168.0.2, 192.168.0.3, 192.168.0.4``, the command would look like: ``tendermint node --proxy_app=kvstore --p2p.persistent_peers=96663a3dd0d7b9d17d4c8211b191af259621c693@192.168.0.1:46656, 429fcf25974313b95673f58d77eacdd434402665@192.168.0.2:46656, 0491d373a8e0fcf1023aaf18c51d6a1d0d4f31bd@192.168.0.3:46656, f9baeaa15fedf5e1ef7448dd60f46c01f1a9e9c4@192.168.0.4:46656``. After a few seconds, all the nodes should connect to each other and start making blocks! For more information, see the Tendermint Networks section of `the guide to using Tendermint `__. While the manual deployment is easy enough, an automated deployment is usually quicker. The below examples show different tools that can be used for automated deployments. Automated Deployments --------------------- Local ^^^^^ With ``docker`` installed, run the command: :: make localnet-start from the root of the tendermint repository. This will spin up a 4-node local testnet. Cloud Deployment using Kubernetes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The `mintnet-kubernetes tool `__ allows automating the deployment of a Tendermint network on an already provisioned Kubernetes cluster. For simple provisioning of a Kubernetes cluster, check out the `Google Cloud Platform `__. Cloud Deployment using Terraform and Ansible ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ See the `next section <./terraform-and-ansible.html>`__ for details.
