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

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
|
2017-08-30 19:36:16 -07:00
|
|
|
already provisioned kubernetes cluster. And for simple provisioning of kubernetes
|
|
|
|
cluster, check out the `Google Cloud Platform <https://cloud.google.com/>`__.
