v0.10.0

Quick Start

kubectl create namespace argo-rollouts
kubectl apply -n argo-rollouts -f https://raw.githubusercontent.com/argoproj/argo-rollouts/v0.10.0/manifests/install.yaml

Notable Features

• Ability to set canary vs. stable ephemeral metadata on rollout Pods during an update
• Support new metric providers: New Relic, Datadog
• Ability to control canary scale during an update
• Ability to restart up to maxUnavailable pods at a time for a canary rollout
• Ability to self reference rollout metadata as arguments to analysis
• Ability to fully promote blue-green and canary rollouts (skipping steps, analysis, pauses)
• kubectl-argo-rollouts plugin command to lint rollout
• kubectl-argo-rollouts plugin command to undo a rollout (same as kubectl rollout undo)

Upgrade Notes

Rollouts v0.10 has switched to using Kubernetes CRD Status Subresources (PR #789). This feature allows the rollout controller to record the numeric metadata.generation into status.observedGeneration which provides a reliable indicator of a Rollout who's spec has (or has not yet) been observed by the controller (for example if the argo-rollouts controller was down or delayed).

A consequence of this change, is that the v0.10 rollout controller should be used with the v0.10 kubectl-argo-rollouts plugin in order to perform actions such as abort, pause, promote. Similarly, Argo CD v1.8 should be with the v0.10 rollout controller when performing those same actions. Both kubectl-argo-rollouts plugin v0.10 and Argo CD v1.8 are backwards compatible with v0.9 rollouts controller.
