配置网关

开始之前

⚠️ 需要你的集群已安装 Ingress 控制器。

字段说明

vela show ingress

# Properties
+--------+------------------------------------------------------------------------------+----------------+----------+---------+

| domain | Specify the domain you want to expose                                        | string         | true     |         |

如何使用

# 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: ingress
          properties:
            domain: testsvc.example.com
            http:
              "/": 8000

部署到集群后，检查应用状态为 running，并且状态是 healthy：

kubectl get application first-vela-app -w

NAME             COMPONENT        TYPE         PHASE            HEALTHY   STATUS   AGE
first-vela-app   express-server   webservice   healthChecking                      14s
first-vela-app   express-server   webservice   running          true               42s

如果你的集群带有云厂商的负载均衡机制可以通过 Application 查看到访问的 IP：

kubectl get application first-vela-app -o yaml

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: first-vela-app
  namespace: default
spec:
...
  services:
  - healthy: true
    name: express-server
    traits:
    - healthy: true
      message: 'Visiting URL: testsvc.example.com, IP: 47.111.233.220'
      type: ingress
  status: running
...

然后就能够通过这个 IP，来访问该应用程序了。

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

                                       ##         .
                                 ## ## ##        ==
                              ## ## ## ## ##    ===
                           /""""""""""""""""\___/ ===
                      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
                           \______ o          _,/
                            \      \       _,'
                             `'--.._\..--''
</xmp>
