Argo events Authorization to eventbus internal NATS

Question

I am trying to connect Argo event source to internal Argo eventbus NATS server. I configured event source

spec:
  nats:
    subtask-create:
      url: nats://eventbus-default-stan-svc:4222
      jsonBody: true
      subject: task-create-finished
      auth:
        clusterID: eventbus-default
        token:
          name: client-auth
          key: eventbus-default-client

but creating eventsource cannot finish and eventbus-controller log contains

{"level":"info","ts":1634109821.5641801,"logger":"argo-events.eventsource-controller","caller":"eventsource/resource.go:92","msg":"deployment is created","namespace":"argo-events","eventSource":"my-nats","deploymentName":"my-nats-eventsource-6x9fl"}

Which log can give me more information?

Answer 1

The problem is wrong token information. The right way is

spec:
  nats:
    subtask-create:
      url: nats://eventbus-default-stan-svc:4222
      jsonBody: true
      subject: task-create-finished
      auth:
        token:
          name: nats-eventbus-token
          key: client-auth

so key is name of key inside of secret which is named in element name. The token has to be inserted in decoded form without quotes and tag. Put it into file and create like this:

kubectl create secret generic nats-eventbus-token --from-file=client-auth=file
