About The Project

Bailo helps you manage the lifecycle of machine learning to support scalability, impact, collaboration, compliance and sharing.

Built With

• Next.js
• Node.js
• MongoDB
• Seldon

Getting Started

Requirements:

• Node v18
• Docker / Docker Compose

Installation:

To run in development mode (modified files on your host machine will be reloaded into the running application):

git clone https://github.com/gchq/Bailo.git && cd Bailo
npm install
npm run certs

# This builds all the Bailo images, rerun it when you update dependencies.
docker compose build --parallel

# Then run the development instance of Bailo.
docker compose up -d

On first run, it may take a while (up to 30 seconds) to start up. It needs to build several hundred TypeScript modules. These are cached however, so future starts only require a few seconds. You should access the site via localhost:8080.

Setup:

Some example schemas are installed by default. More schemas can be added by altering and running the addDeploymentSchema.ts and addUploadSchema.ts files.

npm run script -- addDeploymentSchema
npm run script -- addUploadSchema

NOTE: Scripts are also written in Typescript. In production, run them using node, in development, run them using ts-node or npm run script.

Service Ports:

Service	Host	Notes
Next UI	3000	Stored in frontend
NodeJS App	3001	Stored in backend
Mongo	27017	No credentials
Registry	5000	HTTPS only, no UI
Minio UI	9001	minioadmin:minioadmin
Minio	9000	minioadmin:minioadmin
MailCrab	1080	Fake email server

** Note: these credentials are intentionally basic/default, but in your own instances we recommend changing them to something more secure.

We expect the administrator to provide their own forms of authentication. By default all users authenticate using as 'user'.

You can test out your new deployment using the example models which can be found in __tests__ minimal_binary.zip and minimal_code.zip. There are also example forms in the scripts folder minimal_upload_schema_examples.json and minimal_deployment_schema_examples.json.

Logical Project Flow (Overview)

1. A user accesses a URL. We use NextJS routing to point it to a file in frontend/pages. [xxx].tsx files accept any route, xxx.tsx files allow only that specific route.
2. Data is loaded using SWR. Data loaders are stored in ./frontend/data. Each one exposes variables to specify if it is loading, errored, data, etc.
3. Requests to the backend get routed through express within backend/routes.ts. Each route is an array with all items being middleware except the last, which is the handler ([...middleware, handler]).
4. Routes interact with the database via mongoose, which stores models in ./backend/models.

Some processing is done away from the main thread, when it is expected to take longer than a few milliseconds. These are posted to a mongodb queue and processed by handlers in the backend/processors folder. Mongodb queues are handled invisibly by p-mongo-queue (backend/utils/queues.ts).

Known Issues

Issue: Sometimes Docker struggles when you add a new dependency.

Fix: Run docker compose down --rmi all followed by docker compose up --build.

Issue: Sometimes SWR fails to install its own binary and the project will refuse to start up (development only)

Fix: Run npm uninstall next && npm install next. Some users report still having issues. If so, run: rm -rf node_modules && rm -rf package-lock.json && npm cache clean -f && npm i.

Issue: Unable to authenticate to the Docker registry / compile binaries.

Fix: Make sure that your authentication proxy is setup to allow the 'Authorisation' header. Make sure that your application is able to access the Docker registry internally as it will not provide user authentication.

Roadmap

Breaking Changes

28-04-2022: Changed 'schema' model to be stored as a string instead of an object. Delete & recreate your schemas.
