Stack Orchestrator

Stack Orchestrator allows building and deployment of a Laconic stack on a single machine with minimial prerequisites.

Setup

Developer Mode

Developer mode runs the orchestrator from a cloned git repository.

Prerequisites

Stack Orchestrator is a Python3 CLI tool that runs on any OS with Python3 and Docker. Tested on: Ubuntu 20/22.

Ensure that the following are already installed:

  1. Python3 (the version 3.8 available in Ubuntu 20/22 works)
    $ python3 --version
    Python 3.8.10
    
  2. Docker (Install a current version from dockerco, don't use the version from any Linux distro)
    $ docker --version
    Docker version 20.10.17, build 100c701
    

Install

  1. Clone this repository:
    $ git clone (https://github.com/cerc-io/stack-orchestrator.git
    
  2. Enter the project directory:
    $ cd stack-orchestrator
    
  3. Create and activate a venv:
    $ python3 -m venv venv
    $ source ./venv/bin/activate
    (venv) $
    
  4. Install the cli in edit mode:
    $ pip install --editable .
    
  5. Verify installation:
    (venv) $ laconic-so
    Usage: laconic-so [OPTIONS] COMMAND [ARGS]...
    
     Laconic Stack Orchestrator
    
    Options:
     --quiet
     --verbose
     --dry-run
     -h, --help  Show this message and exit.
    
    Commands:
     build-containers    build the set of containers required for a complete...
     deploy-system       deploy a stack
     setup-repositories  git clone the set of repositories required to build...

Usage

There are three sub-commands: setup-repositories, build-containers and deploy-system that are generally run in order:

Setup Repositories

Clones the set of git repositories necessary to build a system.

Note: the use of ssh-agent is recommended in order to avoid entering your ssh key passphrase for each repository.

$ laconic-so --verbose setup-repositories

Build Containers

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

$ laconic-so --verbose build-containers

Deploy System

Uses docker compose to deploy a system.

Use ---include <list of components> to deploy a subset of all containers:

$ laconic-so --verbose deploy-system --include db-sharding,contract,ipld-eth-server,go-ethereum-foundry up
$ laconic-so --verbose deploy-system --include db-sharding,contract,ipld-eth-server,go-ethereum-foundry down

Implementation

The orchestrator's operation is driven by files shown below. repository-list.txt container the list of git repositories; container-image-list.txt contains the list of container image names, while clister-list.txt specifies the set of compose components (corresponding to individual docker-compose-xxx.yml files which may in turn specify more than one container). Files required to build each container image are stored under ./container-build/<container-name> Files required at deploy-time are stored under ./config/<component-name>
