v0.6.0

Quick Start

kubectl create namespace argo-rollouts
kubectl apply -n argo-rollouts -f https://raw.githubusercontent.com/argoproj/argo-rollouts/v0.6.0/manifests/install.yaml

Important Notices

• The pause functionality was reworked in the v0.6 release. Previously, the .spec.paused field was used by the controller to pause rollouts. However, this was an issue for users who wanted to manually pause the rollout since the controller assumed it was the only entity that set the field. In v0.6, the controller will add a pause condition to the .status.pauseCondition to pause a controller instead of setting spec.paused. The pause condition has a start time and a reason explaining why it paused. This allows users to set the spec.paused field manually and let the controller respect that pause. The v0.6 controller has a migration function to convert pre v0.6 rollouts to the new pause condition. The migration function will be removed in a future release.
• In pre-v0.6 versions, the BlueGreen strategy would have the preview service point at no ReplicaSets if the new ReplicaSet was receiving traffic from the active service. V0.6 changes that behavior to make the preview service always point at the latest ReplicaSet
