Quickstart

kubectl create namespace argo-rollouts
kubectl apply -n argo-rollouts -f https://github.com/argoproj/argo-rollouts/releases/download/v1.0.0/install.yaml

Notable Features

  • New Argo Rollouts UI available in kubectl argo rollouts dashboard
  • Ability to reference existing Deployment workloads instead of inlining a PodTemplate at spec.template
  • Richer Prometheus stats and Kubernetes events
  • Support for Ambassador as a canary traffic router
  • Support canarying using Istio DestinationRule subsets

Upgrade Notes

Installation Manifests

Installation manifests are now attached as GitHub Release artifacts (as opposed to raw files checked into git)
and can be installed with the release download URL. e.g.:

kubectl apply -n argo-rollouts -f https://github.com/argoproj/argo-rollouts/releases/download/v1.0.0/install.yaml

Argo CD OutOfSync status on Rollout v1.0.0 CRDs:

Argo Rollouts v1.0 now vends apiextensions.k8s.io/v1 CustomResourceDefinitions (previously apiextensions.k8s.io/v1beta1). Kubernetes v1 CRDs no longer supports the preservation of unknown fields in objects, and rejects attempts to set spec.preserveUnknownFields: true (the previous default). In order to support a smooth upgrade from Argo Rollouts v0.10 to v1.0, spec.preserveUnknownFields is explicitly set to false in the manifests, despite false being the default, and only option in v1 CRDs. However this causes diffing tools (such as Argo CD) to report the manifest as OutOfSync (since K8s drops the false field).

More information:

To avoid the Argo CD OutOfSync conditions, you can remove spec.preserveUnknownFields from the manifests
entirely after upgrading to v1.0.

Alternatively, you can instruct Argo CD to ignore differences using ignoreDifferences in the Application spec:

spec:
  ignoreDifferences:
  - group: apiextensions.k8s.io
    kind: CustomResourceDefinition
    jsonPointers:
    - /spec/preserveUnknownFields

Deprecation of kubectl argo rollouts promote --skip-current-step flag

The promote flag --skip-current-step which skips the current running canary step has been deprecated and will be removed in a future release. Its logic to skipping the current step has been merged with the existing command:

kubectl argo rollouts promote ROLLOUT

The promote ROLLOUT command can now be used to handle both the case where the rollout needs to be unpaused, as well as to skip the currently running canary step (e.g. an analysis/experiment/pause step).
