Argo CD Git Webhook Configuration

Create The Webhook in GitHub

  • When creating the webhook in GitHub, the “Content type” needs to be set to “application/json“. The default value “application/x-www-form-urlencoded” is not supported by the library used to handle the hooks
  • The webhook handler does not differentiate between branch events and tag events where the branch and tag names are the same. A hook event for a push to branch x will trigger a refresh for an app pointing at the same repo with targetRevision: refs/tags/x.
  • If Argo CD is publicly accessible, then configuring a webhook secret is recommended to prevent a DDoS attack.

Configure Argo CD with The WebHook Secret

# kubectl edit secret argocd-secret -n argocd
