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 >= 3.8.10 (the Python3 shipped in Ubuntu 20+ is good to go)
Docker: docker --version >= 20.10.21
jq: jq --version >= 1.5

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

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 decide on a directory where you would like to put the stack-orchestrator program. Typically this would be a "user" binary directory such as ~/bin or perhaps /usr/local/laconic or possibly just the current working directory.

Now, having selected that directory, download the latest release from this page into it (we're using ~/bin below for concreteness but edit to suit if you selected a different directory). Also be sure that the destination directory exists and is writable:

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

Give it execute permissions:

chmod +x ~/bin/laconic-so

Ensure laconic-so is on the PATH

Verify operation (your version will probably be different, just check here that you see some version outut and not an error):

laconic-so version
Version: v1.0.27-7831078

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 --stack erc20 setup-repositories

This will default to cloning git reposiories into: ~/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 --stack erc20 build-containers

Deploy System

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

laconic-so --stack erc20 deploy-system up

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

See the erc20 watcher demo to continue further.

Cleanup

laconic-so --stack erc20 deploy-system down

Contributing

See the CONTRIBUTING.md for developer mode install.

Platform Support

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