Migrating from other Gateway solutions

Learn how to easily migrate from other Gateway solutions to Tetrate Hosted Agent

From Kubernetes Ingress

If migrating from Kubernetes Ingress:

  rules:
  - host: api.example.com
    http:
      paths:
      - path: /api
        pathType: Prefix
        backend:

            name: api-service
            port:
