ArgoCD path in application, how does it work? Imagine we have a pre-existing namespace as below: If we want to manage the foobar namespace with ArgoCD and to then also remove the foo: bar annotation, in already have labels and/or annotations set on it, you're good to go. Some examples are: Having the team name as a label to allow routing alerts to specific receivers Creating dashboards broken down by business units Please try using group field instead.

The problem is that our pipeline is defined in our gitops-repository and ArgoCD automatically sets a label to the applied objects: If a pipelinerun gets created this run inherits the label. However, diffing configurations werent considered during the sync step, which sometimes leads to undesirable behavior. privacy statement. There's Kubernetes manifests for Deployments, Services, Secrets, ConfigMaps, and many more which all go into a Git repository to be revision controlled.
