- 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. For this deployment, we'll use the
- ``basecoin`` application.
-
- 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``, and a list of the public
- keys of all validators, stored as ``genesis.json``. These files should
- be stored in ``~/.tendermint``, or wherever the ``$TMROOT`` 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 for each validator using
- ``tendermint gen_validator``
- 4) Compile a list of public keys for each validator into a
- ``genesis.json`` file.
- 5) Run ``tendermint node --p2p.seeds=< seed addresses >`` on each node,
- where ``< seed 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 --p2p.seeds=192.168.0.1:46656,192.168.0.2:46656,192.168.0.3:46656,192.168.0.4:46656``.
-
- After a few seconds, all the nodes should connect to eachother and start
- making blocks! For more information, see the Tendermint Networks section
- of `the guide to using Tendermint </docs/guides/using-tendermint>`__.
-
- Automated Deployments
- ---------------------
-
- While the manual deployment is easy enough, an automated deployment is
- always better. For this, we have the `mintnet-kubernetes
- tool <https://github.com/tendermint/tools/tree/master/mintnet-kubernetes>`__,
- which allows us to automate the deployment of a Tendermint network on an
- already provisioned kubernetes cluster.
-
- For more details, see the `mintnet-kubernetes
- directory <https://github.com/tendermint/tools/tree/master/mintnet-kubernetes>`__,
- and check out `Google Cloud Platform <https://cloud.google.com/>`__ for
- simple provisioning of kubernetes clusters.
