DeploymentSet

A deployment-set describes a deployment and the namespaces it should be installed in.

Useful if you want to install many isolated controllers that control their own namespace

Run the controller in any namespaces, and in that same namespace create a DeploymentSet.

This example creates an Argo Workflows controller in each namespace labelled with "workflows.argoproj.io/argo": "true"

apiVersion: alexec.alexec/v1
kind: DeploymentSet

  selector:
    matchLabels:

      name: workflow-controller
    spec:
