Troubleshooting

Troubleshooting

The argocd-notifications binary includes a set of CLI commands that helps to configure the controller settings and troubleshoot issues.

Global flags

Following global flags are available for all sub-commands:

  • config-map - path to the file containing argocd-notifications-cm ConfigMap. If not specified then the command loads argocd-notification-cm ConfigMap using the local Kubernetes config file.
  • secret - path to the file containing argocd-notifications-secret ConfigMap. If not specified then the command loads argocd-notification-secret Secret using the local Kubernetes config file. Additionally, you can specify :empty value to use empty secret with no notification service settings.

Examples:

  • Get list of triggers configured in the local config map:
argocd-notifications trigger get \
  --config-map ./argocd-notifications-cm.yaml --secret :empty
  • Trigger notification using in-cluster config map and secret:
argocd-notifications template notify \
  app-sync-succeeded guestbook --recipient slack:argocd-notifications

Kustomize

If you are managing argocd-notifications config using Kustomize you can pipe whole kustomize build output into stdin using --config-map - flag:

kustomize build ./argocd-notifications | \
  argocd-notifications \
  template notify app-sync-succeeded guestbook --recipient grafana:argocd \
  --config-map -

How to get it

On your laptop

You can download argocd-notifications from the github release attachments.

The binary is available in argoprojlabs/argocd-notifications image. Use the docker run and volume mount to execute binary on any platform.

Example:

docker run --rm -it -w /src -v $(pwd):/src \
  argoprojlabs/argocd-notifications:<version> \
  /app/argocd-notifications trigger get \
  --config-map ./argocd-notifications-cm.yaml --secret :empty

In your cluster

SSH into the running argocd-notifications-controller pod and use kubectl exec command to validate in-cluster configuration.

Example

kubectl exec -it argocd-notifications-controller-<pod-hash> \
  /app/argocd-notifications trigger get
