2.2.0 (2018-08-30)

Notes about upgrading from v2.1

  • The argo install and argo uninstall commands have been removed from the CLI. Instead, plain
    kubernetes manifests are provided to be installed using kubectl apply, or downstreamed into other
    tools (e.g. helm chart, ksonnet prototype, kustomize, etc...).

  • In 2.1, argo would install into the kube-system namespace by default. The new install instructions
    have been updated to install into a different namespace, argo. In order to move to the recommended
    installation location, you should delete the v2.1 resources from kube-system before applying the
    new manifests to the argo namespace.

    The following commands migrates the workflow-controller-configmap from the kube-system to the
    argo namespace, and deletes all argo resources from the kube-system namespace. Note that this
    will delete the argo-ui service, resulting in the LoadBalancer being deleted (if created).

    kubectl get cm workflow-controller-configmap -o yaml -n kube-system --export | kubectl apply -n argo -f -
kubectl delete -n kube-system cm workflow-controller-configmap
kubectl delete -n kube-system deploy workflow-controller argo-ui
kubectl delete -n kube-system sa argo argo-ui
kubectl delete -n kube-system svc argo-ui

  • In 2.1, the argoexec sidecar image was configured in the workflow-controller-configmap. This is
    now configured using a new --executor-image flag in the workflow-controller deployment. This is
    the preferred way to configure the executor image, since upgrades can now be performed without
    changing the workflow-controller configmap. The executorImage setting in the config is deprecated
    and may be removed/ignored in a future release.
