复制链接

Suppose you have a file named route.yaml with this content: 

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command. 

camel run route.yaml
