Major Changes

• JetStream EventBus implementation, it is used to replace current Nats Streaming implementation which will be end of life in 2023. With JetStream EventBus, duplicate dependencies restrictions are removed. Thanks to @juliev0 for the implementation.
• Redis Stream EventSource support, thanks to @BulkBeing .
• Combine controllers (eventbus-controller, eventsource-controller and sensor-controller) to one.
• Controller HA support, thanks to @davidcollom .

Installation

kubectl create namespace argo-events
kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/v1.7.0-rc1/manifests/install.yaml

# Install validating webhook (optional)
kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/v1.7.0-rc1/manifests/install-validating-webhook.yaml

Upgrade

Since we combined the original three controllers to one, you need to delete the deployments before upgrading.

kubectl -n argo-events delete deploy eventbus-controller
kubectl -n argo-events delete deploy eventsource-controller
kubectl -n argo-events delete deploy sensor-controller
