Getting started Seldon Core
There are 3 steps to using seldon-core.
- Install seldon-core onto a Kubernetes cluster
- Wrap your components (usually runtime model servers) as Docker containers that respect the internal Seldon microservice API.
- Define your runtime service graph as a SeldonDeployment resource and deploy your model and serve predictions
Install Seldon Core
To install seldon-core follow the installation guide.
Wrap Your Model
The components you want to run in production need to be wrapped as Docker containers that respect the Seldon microservice API. You can create models that serve predictions, routers that decide on where requests go, such as A-B Tests, Combiners that combine responses and transformers that provide generic components that can transform requests and/or responses.
To allow users to easily wrap machine learning components built using different languages and toolkits we provide wrappers that allow you easily to build a docker container from your code that can be run inside seldon-core. Our current recommended tool is RedHat's Source-to-Image. Wrapping your models is discussed here.
Define Runtime Service Graph
To run your machine learning graph on Kubernetes you need to define how the components you created in the last step fit together to represent a service graph. This is defined inside a SeldonDeployment Kubernetes Custom resource. A guide to constructing this custom resource service graph is provided.
Deploy and Serve Predictions
You can use
kubectl to deploy your ML service like any other Kubernetes resource. This is discussed here.
