Setting Routes

The route section is used to configure the access to your app.

Prerequisite

Make sure route trait controller is installed in your cluster

Install route trait controller with helm

1. Add helm chart repo for route trait

   helm repo add oam.catalog  http://oam.dev/catalog/
   

2. Update the chart repo

   helm repo update
   

3. Install route trait controller

   helm install --create-namespace -n vela-system routetrait oam.catalog/routetrait
   
   
   

Note: route is one of the extension capabilities installed from cap center, please install it if you can't find it in vela traits.

Setting route policy

Add routing config under express-server:

services:
  express-server:
    ...

    route:
      domain: example.com
      rules:
        - path: /testapp
          rewriteTarget: /

The full specification of route could show up by $ vela show route.

Apply again:

$ vela up

Check the status until we see route is ready:

$ vela status testapp
