Installation Id

Settings location: argocd-cm Configmap

Optional installation id. Allows to have multiple installations of Argo CD in the same cluster.

apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-cm
data:
  installationID: "my-unique-id"

If you are managing one cluster using multiple Argo CD instances, you will need to set installationID in the Argo CD ConfigMap. This will prevent conflicts between the different Argo CD instances:

• Each managed resource will have the annotation argocd.argoproj.io/installation-id: <installation-id>
• It is possible to have applications with the same name in Argo CD instances without causing conflicts.
