# 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/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 repo](https://github.com/tendermint/mintnet-kubernetes),
and check out [Google Cloud Platform](https://cloud.google.com/) for simple provisioning of kubernetes clusters.

TODO: a better tutorial here, and Ansible/Terraform.
