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.
### User Mode
Developer mode runs the orchestrator from a "binary" single-file release.
#### 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)
1. Python3 (the stock Python3 version available in Ubuntu 20 and 22 is suitable)
```
$ python3 --version
Python 3.8.10
```
1. Python venv package
This may or may not be already installed depending on the host OS and version. Check by running:
```
$ python3 -m venv
usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear] [--upgrade] [--without-pip] [--prompt PROMPT] ENV_DIR [ENV_DIR ...]
venv: error: the following arguments are required: ENV_DIR
```
If the venv package is missing you should see a message indicating how to install it, for example with:
```
$ apt install python3.8-venv
```
2. Docker (Install a current version from dockerco, don't use the version from any Linux distro)
```
$ docker --version
