argocd-slack-notification

To be used with ArgoCD Hooks for sending Slack attachment

Helm templates

values.yaml

argocd:
  enabled: true
  namespace:
  url:
  appName:
  slack:
    channel:
    pretext: # Freetext; for example identifying an enviornment "Production enviornment"
    hooks: # Hooks on which the job should be triggered
      - PostSync
      - SyncFail
...

secrets.yaml

Provide either argocdAdminPass or argocdToken but I strongly recommended if you create a GET only Role in ArgoCD create static token for that role and use argocdToken

apiVersion: v1
kind: Secret
metadata:
  name: argo-hook-secrets
  namespace: {{ $.Values.argocd.namespace }}
stringData:
  argocdAdminPass: ""
  argocdToken: ""
  githubToken: ""
  slackWebhookUrl: ""

If you use Admin password then change

- name: ARGOCD_TOKEN
  valueFrom:
    secretKeyRef:
      name: argo-hook-secrets
      key: argocdToken

to 

- name: ARGOCD_ADMIN_PASS
  valueFrom:
    secretKeyRef:
    name: argo-hook-secrets
    key: argocdAdminPass
