v2.3.0

Quick Start

kubectl create namespace argo
kubectl apply -n argo -f https://raw.githubusercontent.com/argoproj/argo/v2.3.0/manifests/install.yaml

Changelog since v2.2

Notes about upgrading from v2.2

• Artifact repository secrets are passed to the wait sidecar using volumeMounts instead of the
  previous behavior of performing K8s API calls performed by the executor. This is much more secure
  since it removes privileges of the workflow pod to no longer require secret access. However, as a
  consequence, workflow pods which reference a secret that does not exist, will now indefinitely
  stay in a Pending state, as opposed to the previous behavior of failing during runtime.

Deprecation Notice

The workflow-controller-configmap introduces a new config field, executor, which is a container
spec and provides controls over the executor sidecar container (i.e. init/wait). The fields
executorImage, executorResources, and executorImagePullPolicy are deprecated and will be
removed in a future release.

• Support for PNS (Process Namespace Sharing) executor (#1214)
