Developer Portal Controller

Developer Portal APIs and Controllers for Kubernetes-based API management.

Overview

The Developer Portal Controller provides Kubernetes Custom Resource Definitions (CRDs) for managing API products and API keys in a developer portal ecosystem. It integrates with Kuadrant and Gateway API to provide a complete API lifecycle management solution.

Custom Resources

APIProduct

The APIProduct resource represents an API offering in the developer portal. It references an HTTPRoute and can include documentation, contact information, and usage plans.

Development environment setup

Dev env

make kind-create-cluster
make install
make gateway-api-install
make kuadrant-core-install

Deploy controller

make local-deploy

Usage

Creating an APIProduct

1. Create an HTTPRoute for your API
2. Create a PlanPolicy to define rate limits and tiers
3. Create an APIProduct referencing the HTTPRoute

Requesting an APIKey

1. Create an APIKey resource referencing the APIProduct
2. If approvalMode is manual, wait for approval
3. Once approved, the secret will be created with the API key
4. Use the key from the secret to authenticate API requests

kubectl Commands

# List APIKeys (shortname: apik)
kubectl get apik

# View APIKey details with phase and plan
kubectl get apik -o wide

# Describe an APIKey to see status details
kubectl describe apikey toystore-apikey
