Stack Orchestrator

Stack Orchestrator allows building and deployment of a Laconic Stack on a single machine with minimial prerequisites. It is a Python3 CLI tool that runs on any OS with Python3 and Docker. The following diagram summarizes the relevant repositories in the Laconic Stack - and the relationship to Stack Orchestrator.

Install

Ensure that the following are already installed:

• Python3: python3 --version >= 3.10.8
• Docker: docker --version >= 20.10.21
• Docker Compose: docker-compose --version >= 2.13.0

Note: if installing docker-compose via package manager (as opposed to Docker Desktop), you must install the plugin, e.g., on Linux:

mkdir -p ~/.docker/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.11.2/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
chmod +x ~/.docker/cli-plugins/docker-compose

Next, download the latest release from this page, into a suitable directory (e.g. ~/bin):

curl -L -o ~/bin/laconic-so https://github.com/cerc-io/stack-orchestrator/releases/latest/download/laconic-so

Give it permissions:

chmod +x ~/bin/laconic-so

Ensure laconic-so is on the PATH

Verify operation:

laconic-so --help
Usage: python -m laconic-so [OPTIONS] COMMAND [ARGS]...

  Laconic Stack Orchestrator

Options:

  --verbose
  --dry-run
  --local-stack
  -h, --help     Show this message and exit.

Commands:

  deploy-system       deploy a stack
  setup-repositories  git clone the set of repositories required to build...

Usage

Three sub-commands: setup-repositories, build-containers and deploy-system are generally run in order. The following is a slim example for standing up the erc20-watcher. Go further with the erc20 watcher demo and other pieces of the stack, within the stacks directory.

Setup Repositories

Clone the set of git repositories necessary to build a system:

laconic-so --verbose setup-repositories --include cerc-io/go-ethereum,cerc-io/ipld-eth-db,cerc-io/ipld-eth-server,cerc-io/watcher-ts

This will default to ~/cerc or - if set - the environment variable CERC_REPO_BASE_DIR

Build Containers

Build the set of docker container images required to run a system. It takes around 10 minutes to build all the containers from scratch.

laconic-so --verbose build-containers --include cerc/go-ethereum,cerc/go-ethereum-foundry,cerc/ipld-eth-db,cerc/ipld-eth-server,cerc/watcher-erc20

Deploy System

Uses docker-compose to deploy a system (with most recently built container images).

laconic-so --verbose deploy-system --include ipld-eth-db,go-ethereum-foundry,ipld-eth-server,watcher-erc20 up

Check out he GraphQL playground here: http://localhost:3002/graphql

See the erc20 watcher demo to continue further.

Cleanup

laconic-so --verbose deploy-system --include ipld-eth-db,go-ethereum-foundry,ipld-eth-server,watcher-erc20 down

Platform Support

Native aarm64 is not currently supported. x64 emulation on ARM64 macos should work (not yet tested).
