Getting Started

Requirements

To run the server locally, you will need the following installed:

  • Python 3.6+
  • NPM
  • yarn
  • redis (strongly recommend a container)
  • PostgreSQL (strongly recommend a container)

To run the containers, you will need either one of the following installed:

  • Docker
  • Podman

Run the Frontend

When running on your local computer, the server is made up of two parts, the frontend and the backend. The backend runs the api while the frontend hosts the UI. First, install yarn if you don't have it already, and set up the frontend.

Many Linux distributions offer Yarn in their package repositories. Both Debian and Fedora package Yarn as yarnpkg.

Install Yarn on Fedora:

sudo dnf install -y yarnpkg

Install Yarn on Debian:

sudo apt install yarnpkg

If you don't wnat to use the packaged version of Yarn, you can install it via npm:

cd ibutsu-server/frontend
npm install yarn

Just remember that you'll need to specify the full path when running Yarn:

node_modules/.bin/yarn <action>

Now that Yarn is installed, use Yarn to install the frontend's dependencies:

yarn install

Then to start the development server for the frontend using yarn:

yarn run devserver

The development server features automatic reloading, so that whenever you make a change to your code, the server will rebuild your app and run the new code.

Open your browser and go to localhost:3000 to see the web UI.

Run PGSQL and Redis

Next you'll need to set up a PostgreSQL server. It is easiest to just run the server in a container:

Note

In all these examples, we use podman, but you can substitute docker in its place.

podman run --publish 5432:5432 --name postgres -e POSTGRES_USER=ibutsu -e POSTGRES_PASSWORD=ibutsu -e POSTGRES_DB=ibutsu -d postgres

If you don't have redis installed locally, you'll want to also run a redis container. This is required for celery.

podman run --name redis -d -p "6379:6379" redis

Install Dependencies

You'll want to set up a virtual environment for the backend, and install the dependencies:

cd ibutsu-server/backend
virtualenv .ibutsu-env --python python3
.ibutsu-env/bin/pip install -r requirements.txt

Run Celery Worker

Start the celery worker using the backend/celery_worker.sh script or via:

celery worker -E -A ibutsu_server.tasks.queues:app --loglevel=info

Note

The -E is necessary to send task related events to the celery task monitor.

(Optional) Start the celery task monitor:

.ibutsu-env/bin/python ibutsu_server/tasks/monitor.py

The task monitor checks the task queue for failures.

Run the API Backend

Run the Ibutsu server backend using Python:

.ibutsu-env/bin/python -m ibutsu_server

By default, the backend runs on port 8080, so your backend URL will be http://localhost:8080
