Teztnets

Infrastructure-as-code repo to activate and bootstrap Tezos testnets in a repeatable, automated way.

See teztnets.xyz for the list of active Teztnets.

Features

Based on tezos-k8s

tezos-k8s is a framework to deploy Tezos nodes or chains using Kubernetes and Helm.

See the tezos-k8s documentation

Faucet support

The commitments are precursor accounts that can be used to fund real account with the faucet.

Injection of contracts at genesis

A collection of raw Michelson contracts can be optionally deployed in any Teztnet at genesis.

Bootstrap baker and bootstrap p2p endpoint

Upon deployment of a Teztnet, a genesis baker will run and its p2p and rpc endpoints will be exposed externally. Example:

• p2p: hangzhounet.teztnets.xyz
• rpc rpc.hangzhounet.teztnets.xyz

--network endpoint for Tezos node

Tezos nodes supports downloading of network specification from a json endpoint: tezos-node config init --network https://teztnets.xyz/<TEZTNET NAME>

The Teztnet platform creates and exposes such endpoints.

Currently deployed Teztnets

Deployment of new testnets is performed with Github Releases.

The most recent release on the Release page has a list of currently deployed testnets, with URLs to connect to them.

Automate on Teztnets

You are encouraged to build automation to ensure your Tezos project keeps running with the future versions of Tezos shell and/or protocol.

1. monitor this repo's releases using your monitoring tool of choice
2. this endpoint lists the current active testnets: https://teztnets.xyz/teztnets.json

Add new Teztnets or modify existing Teztnets

Every Teztnet is defined in a directory in this repository. The Teztnet directory must contain the following files:

• A Helm chart values.yaml file
• optionally, a submodule of tezos-k8s (in case you need an unreleased or custom version of the tezos-k8s software)

Helm chart values.yaml

The Helm chart values.yaml lets you customize your chain in many ways:

• specify activation parameters, such as:
  • list of genesis bakers
  • list of accounts funded at genesis
  • chains parameters (blocks per cycle, time between blocks...)
• specify user-activated upgrades for hard-forks at a given length
• specify the list of baker/endorser binaries to run.

Look in any Teztnet directory's values.yaml file for reference as to how to configure your own Teztnet.

The default Helm values.yaml has details on every possible way to customize your teztnet.

Teztnets.xyz website

The website is created with Jekyll from Markdown files generated from Jinja templates based on Pulumi outputs.

To build the website locally, from the top-level dir of the repo:

1. source .env to populate the secret env vars
2. run pulumi stack output networks > networks.json
3. run pulumi stack output teztnets > teztnets.json
4. run python src/release.py
5. cd target/release
6. run bundle install
7. run bundle exec jekyll serve

The website will be rendered on localhost:4000.
