Gateway for Public Access

The gateway trait exposes a component to public Internet via a valid domain.

How to use

Attach a gateway trait to the component you want to expose and deploy.

# vela-app.yaml
apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: first-vela-app
spec:
  components:
    - name: express-server
      type: webservice
      properties:
        image: crccheck/hello-world
        port: 8000
      traits:
        - type: gateway
          properties:
            domain: testsvc.example.com
            http:
              "/": 8000

vela up -f https://raw.githubusercontent.com/oam-dev/kubevela/master/docs/examples/vela-app.yaml

application.core.oam.dev/first-vela-app created

Check the status until we see status is running:

You can also get the endpoint by:

vela status first-vela-app --endpoint

|--------------------------------|----------------------------+
|    REF(KIND/NAMESPACE/NAME)    |          ENDPOINT          |
|--------------------------------|----------------------------+
| Ingress/default/express-server | http://testsvc.example.com |
|--------------------------------|----------------------------+

Then you will be able to visit this application via its domain.

curl -H "Host:testsvc.example.com" http://<your ip address>/
