service-catalog

Introduction

The service-catalog project is in incubation to bring integration with service brokers to the Kubernetes ecosystem via the Open Service Broker API. A service broker is an endpoint that manages a set of services. The end-goal of the service- catalog project is to provide a way for Kubernetes users to consume services from brokers and easily configure their applications to use those services, without needing detailed knowledge about how those services are created / managed.

As an example:

Most applications need a datastore of some kind. The service-catalog allows Kubernetes applications to consume services like databases that exist somewhere in a simple way:

1. A user wanting to consume a database in their application browses a list of available services in the catalog

2. The user asks for a new instance of that service to be provisioned

   Provisioning means that the broker somehow creates a new instance of a service. This could mean basically anything that results in a new instance of the service becoming available. Possibilities include: creating a new set of Kubernetes resources in another namespace in the same Kubernetes cluster as the consumer or a different cluster, or even creating a new tenant in a multi-tenant SaaS system. The point is that the consumer doesn't have to be aware of or care at all about the details.

3. The user binds that service to their application

   Binding means that the application is injected with the information necessary to use the service, such as coordinates, credentials, and configuration items. Applications are injected using the existing application configuration primitives in Kubernetes: Services, Secrets, and ConfigMaps.

Overall Status

We are currently working toward a beta-quality release to be used in conjunction with Kubernetes 1.6. See the milestones list for information about the issues and PRs in current and future milestones.

NOTE: Some fields in our API will still be considered ALPHA after the API graduates to BETA. These fields are prefixed with alpha in JSON/YAML. Alpha fields are provided for use at your own risk, may not work correctly, may be subject to change or removal at any time, and will not have data migration provided for them when they graduate past alpha. When an alpha field graduates past alpha, the alpha prefix will be removed.

The project roadmap contains information about our high-level goals for future milestones.

We are currently making weekly releases; see the release process for more information.

Documentation

Our goal is to have extensive use-case and functional documentation.

See here for documentation.

See here for examples and here for broker servers that are compatible with this software.

Terminology

This project's problem domain contains a few inconvenient but unavoidable overloads with other Kubernetes terms. Check out our terminology page for definitions of terms as they are used in this project.

Contributing

Interested in contributing? Check out the documentation.

Also see the developer's guide for information on how to build and test the code.

We have weekly meetings - see Kubernetes SIGs (search for "Service Catalog") for the exact date and time. Our agenda/notes doc can be found here.
