# 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
|
|
```
|
|
1. 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
|
|
```
|
|
1. Enter the project directory:
|
|
```
|
|
$ cd stack-orchestrator
|
|
```
|
|
1. Create and activate a venv:
|
|
```
|
|
$ python3 -m venv venv
|
|
$ source ./venv/bin/activate
|
|
(venv) $
|
|
```
|
|
1. Install the cli in edit mode:
|
|
```
|
|
$ pip install --editable .
|
|
```
|
|
1. 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.

|
|

|
|
deploy-system deploy a stack
|
|
setup-repositories git clone the set of repositories required to build...
|
|
```
|
|
### CI Mode

|
|
|
|
## 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>`
