I have a question about setting up slack in argocd-notifications-secret's notifiers.yaml.

Hello! 😃

I am very interested in your work.
I've been waiting for the notification feature on the Argo CD.
Thank you for your works!

Back to the point, so I tried to test your project right away.

So I tried to test your project right away.

But setting up Slack is too difficult.
I'm wonder that what tokens does mean in the https://argoproj-labs.github.io/argocd-notifications/ documentation?
How can I find this token?

Please Let me know.
Thank you.

First you need to create a new App in your Slack workspace: https://api.slack.com/apps?new_app=1

Then, in OAuth & Permissions, add a new OAuth scope chat:write:bot. Scroll up and click Install App to Workspace and complete the setup. Afterwards you will see the OAuth Access Token which you can use for Argo CD notifications.

I hope that helps 🙂

Can I ask additional questions?

As you answered, I created a Slack App and received an OAuth token for chat:write:bot And I set a argocd-notifications-secret with this token.
But the message doesn't come to my slack channel.. 😢

Here's what I worked on:

Copied the contents of https://raw.githubusercontent.com/argoproj-labs/argocd-notifications/stable/manifests/install.yaml in my local.

And I edited as below :

...
apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-notifications-cm
data:
  config.yaml: |
    triggers:
      name: on-sync-succeeded
        condition: on-sync-succeeded
        template: app-sync-succeeded
        enabled: true
    templates:
      name: app-sync-status
        title: Application {{.app.metadata.name}} sync status is {{.app.status.sync.status}}
        body: |
          Application {{.app.metadata.name}} sync is {{.app.status.sync.status}}.
          Application details: {{.context.argocdUrl}} / applications / {{. App.metadata.name}}
---
apiVersion: v1
kind: Secret
metadata:
  name: argocd-notifications-secret
stringData:
  notifiers.yaml: |
    slack:
      token: <My slack apps OAuth access token>
type: Opaque
...

Then I proceeded to apply with the following command :
kubectl apply -n argocd -f install.yaml

And I changed the contents of Application distributed through Argo CD with the following command :

my app name: test-app
my slack channel name: product-argo-cd

kubectl patch app test-app -n argocd -p '{"metadata": {"annotations": {"recipients.argocd-notifications.argoproj.io": "slack: product-argo-cd"}}}'- type merge

I just worked like this.
Have you missed anything?

[muenchdo]

There shouldn't be a space in your annotation, it should be slack:product-argo-cd. You also might need to add the Slack App to your product-argo-cd channel.

(I can also really recommend joining the Argo community Slack)

@muenchdo

As you answered, I removed the whitespace and tried again, but still no message.. 😞
As you've recommended, I'll ask you to join the Argo community Slack channel.
Thank you for your help! 👍
