ArgoCD

ArgoCD source plugin sends events from ArgoCD to configured communication platforms. During startup, the plugin configures ArgoCD webhooks, triggers, templates and subscriptions based on the ArgoCD Notification Catalog. It uses native ArgoCD notifications configuration to send the events to Botkube communication platforms.

The plugin is hosted in the official Botkube plugin repository. To enable the GitHub plugin, ensure that the botkube repository is defined under plugins in the values.yaml file.

botkube:
url: https://github.com/kubeshop/botkube/releases/download/v1.6.0/plugins-index.yaml

Prerequisite elevated RBAC permissions​

ArgoCD plugin requires specific RBAC permissions. If you use Botkube self-hosted installation in version 1.4.1 or newer, you can create them during Botkube install/upgrade by specifying --set="rbac.groups.argocd.create=true" override.

However, you can also create them manually:

cat > /tmp/argocd-rbac.yaml << ENDOFFILE
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: argocd
rules:
- apiGroups: [""]
resources: ["configmaps"]
verbs: ["get", "update"]
- apiGroups: ["argoproj.io"]
resources: ["applications"]
verbs: ["get", "patch"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: argocd
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: argocd
subjects:
- kind: Group
name: argocd
apiGroup: rbac.authorization.k8s.io
ENDOFFILE

kubectl apply -f /tmp/argocd-rbac.yaml

Next, use the argocd group in the plugin RBAC configuration:

"argocd":
botkube/argocd:
enabled: true
config:
# ...
context:
rbac:
group:
type: Static
static:
values: ["argocd"]

Enabling plugin​

note

In order to enable the plugin, ArgoCD has to be already installed on the cluster and all watched Applications need to be created.

Also, remember to create RBAC resources for the plugin. See the Elevated RBAC permissions required) section.

To enable the ArgoCD plugin and watch a single ArgoCD Application named guestbook in argocd Namespace, add the following flag to the Botkube install command:

--set 'sources.argocd.botkube/argocd.enabled'=true \
--set='rbac.groups.argocd.create'=true \ # flag available in Botkube 1.4.1+
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[0].name'=guestbook \
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[0].namespace'=argocd

You can watch multiple ArgoCD Applications by specifying config.defaultSubscriptions.applications[n] values, such as:

--set 'sources.argocd.botkube/argocd.enabled'=true  \
--set='rbac.groups.argocd.create'=true \ # flag available in Botkube 1.4.1+
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[0].name'=first-app \
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[0].namespace'=first-app-ns \
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[1].name'=second-app \
--set 'sources.argocd.botkube/argocd.config.defaultSubscriptions.applications[1].namespace'=second-app-ns

Syntax​

Basic configuration​

This section lists all basic configuration options for the ArgoCD source plugin. The ArgoCD notification config is created automatically during plugin startup and uses triggers and templates based on the ArgoCD Notification Catalog.

sources:
"argocd":
botkube/argocd:
enabled: true
context:
rbac:
group:
type: Static
static:
values: ["argocd"]
# Config contains configuration for ArgoCD source plugin.
# This section lists only basic options, and uses default triggers and templates
# which are based on ArgoCD Notification Catalog ones (https://github.com/argoproj/argo-cd/blob/master/notifications_catalog/install.yaml).
# Advanced customization (including triggers and templates) is described in the documentation.
config:
defaultSubscriptions:
# -- Provide application name and namespace to subscribe to all events for a given application.
applications:
- name: "guestbook"
namespace: "argocd"
argoCD:
# ArgoCD UI base URL. It is used for generating links in the incoming events.
uiBaseUrl: http://localhost:8080
# ArgoCD Notifications ConfigMap reference.
notificationsConfigMap:
name: argocd-notifications-cm
namespace: argocd

Advanced configuration​

You can customize all triggers, templates, webhook registration and more. For advanced properties, see the default-config.yaml file.

Cleanup​

When you disable the plugin, it won't revert all changes made during the plugin startup. To clean up all ArgoCD follow the manual steps:

  • Clean up ArgoCD Notifications ConfigMap. It is usually named argocd-notifications-cm in the argocd Namespace.

    Remove all properties that contains b- or botkube- prefixes in the name.

    • Webhook property name follows the syntax service.webhook.{webhook-name}. For example, the service.webhook.b-784e property was created by Botkube.
    • Template property name follows the syntax template.{template-name}. For example, the template.template.botkube-argocd-ch05k-app-health-degraded property was created by Botkube.
    • Trigger property name follows the syntax trigger.{trigger-name}. For example, the trigger.b-372839f86ed61c4c88 property was created by Botkube.
  • Remove all argocd.argoproj.io/notifications annotations from ArgoCD Applications which contain b- prefix in the trigger and webhook names.

    The annotation key pattern is notifications.argoproj.io/subscribe.{trigger-name}.{webhook-name}. For example, the annotation notifications.argoproj.io/subscribe.b-5cc4c004df01230f72.b-efc0: "" was created by Botkube and it should be deleted if the plugin is disabled.
