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 <using-tendermint.html>`__.
|
|
|
|
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 <https://github.com/tendermint/tools/tree/master/mintnet-kubernetes>`__
|
|
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 <https://cloud.google.com/>`__.
|
|
|
|
Cloud Deployment using Terraform and Ansible
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
See the `next section <./terraform-and-ansible.html>`__ for details.
