Implement Gateway Platform Service

[reshnm]

Understand the Task

Implement the Gateway Platform Service that is able to deploy gateway controllers to platform cluster and workload clusters.

• Multiple MCP Service Provider shall share Ingress/Gateway controller where possible and feasable
• The Ingress/Gateway Platform Service shall also handle DNS entries and certificates.
• Service providers should be able to rely on the availability of CRDs like HTTPRoute.
• A Gateway Platform Service should create a default Gateway on all clusters that contain workload.
• Service providers can create HTTPRoutes for their own webhooks.

A platform service installation could look like this:

apiVersion: openmcp.cloud/v1alpha1
kind: PlatformService
metadata:
  name: gateway
spec:
  providerConfig:
    deployOnClusters:
      purposes:
      - workload
      - platform
  deploymentConfig:

• Successful demonstration in Review
