AMQP事件:argo-工作流未触发

Question

我正在尝试运行一个由事件源触发的argo工作流，它侦听在RabbitMQ上发布的消息。我在这里遵循了准确的步骤：AMQP-Argo事件

RabbitMQ控制器pod正在运行：

eventbus-controller-7b5bd8b7fd-nggrc      1/1     Running   0          4h24m
events-webhook-6d4dc5b476-fnf6x           1/1     Running   0          4h24m
eventsource-controller-57b6cff5c8-xhfwd   1/1     Running   0          4h24m
rabbitmq-controller-949wp                 1/1     Running   0          178m
sensor-controller-6f5b54468-8ndft         1/1     Running   0          4h24m

当我使用以下方法在exchange测试上发布消息时：

import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
channel.basic_publish(exchange='test',
                      routing_key='hello',
                      body='{"message": "hello"}')

然后登录到吊舱

kubectl logs pod/<RABBITMQ-CONTROLLER-POD> -n argo-events

我得到了

2021-09-01 22:58:56.437190+00:00 [info] <0.3934.0> accepting AMQP connection <0.3934.0> (127.0.0.1:58396 -> 127.0.0.1:5672)
2021-09-01 22:58:56.442906+00:00 [info] <0.3934.0> connection <0.3934.0> (127.0.0.1:58396 -> 127.0.0.1:5672): user 'guest' authenticated and granted access to vhost '/'

但是，当我查看工作流时，我没有看到任何工作流

argo list -n argo-events

因此，传感器似乎没有被触发。有人能告诉我我做错了什么吗？

谢谢!

我只能建议(作为仍在从事基本dev实现的人)检查模板/示例文件是否设置了适当的凭据和服务帐户--当资源触发器无法工作时，我也有一段时间感到困惑。

编辑:您还应该验证传感器是否有一个适当的服务帐户(参见https://argoproj.github.io/argo-events/service-accounts/)。
