Dapr 1.2.0

We're happy to announce the release of Dapr 1.2.0!

We would like to extend our thanks to all the new and existing contributors who helped make this release happen.

Highlights

If you're new to Dapr, visit the getting started page and familiarize yourself with Dapr.

  • Support for Pub/Sub event without CloudEvent wrapping, enabling communication between Dapr and non-Dapr applications 2308. This enables Dapr to send and receive events to integrate with applications that cannot use CloudEvents. See Pub/Sub without CloudEvents documentation for details.
  • Ability to scope the APIs that are available on Dapr sidecar through ACLs 3054. For example, if you want to restrict access to only the secrets API from the applications, you can set ACLs on its access. See How-To: Selectively enable Dapr APIs on the Dapr sidecar documentation for details.
  • Ability to "opt-in" to preview features that are included in releases. This provides a way to introduce new features that still need feedback before being made GA in quality. Equally expect that preview features from previous releases (currently none) can be removed without a deprecation notice. 3048. See How-To: Enable preview features documentation for details.
  • In this release Actor Re-entrancy 21 is included as a opt-in preview feature for Actors. Reentrancy enables actor A to call actor B which can then call actor A again without the call blocking. See How-to: Enable and use actor reentrancy in Dapr documentation for details.
  • Consul as a DNS name resolution component 749 enables Dapr to preform service discovery and use the service invocation API in VM scenarios that can be joined in the same network. This means that Dapr now supports Kubernetes,VMs and physical machines as production hosting enviroments with DNS resolution enabled in each. See HashiCorp Consul component spec documentation for details.
  • As a result of the Consul intergration Name resolution components are now first class component types that can be "swapped" in the same manner as any other component type through Dapr configuration settings. See Name resolution component specs documentation for details.
  • Many new components:
    • Alibaba Cloud DingTalk Webhook as Binding 811
    • Zeebe Workflow Engine as Binding 805
    • Alibaba Sentinel as Middleware 828
    • Consul name resolution component 749
  • The Dapr docs have been updated with all the new features and changes of this release. To get started with new capabilities introduced in this release, go to the Concepts and the Developing applications or follow the links above. Updates to documentation are listed below.

For more information on the features listed above watch the Dapr Community Call #38 and the upcoming Community call #39

See this section on upgrading Dapr to version 1.2.0.

Deprecation Notice

The GET /v1.0/shutdown HTTP API is deprecated and scheduled for removal in 1.4. All users who have directly integrated with this API should use the POST /v1.0/shutdown API instead. If you are using one of the supported Dapr SDKs you do not need to take any action.

See https://docs.dapr.io/operations/hosting/kubernetes/kubernetes-job/ for an example usage of this API.

Upgrading to Dapr 1.2.0

To upgrade to this release of Dapr, follow the steps here to ensure a smooth upgrade. You know, the one where you don't get red errors on the terminal.. we all hate that, right?

Local Machine / Self-hosted

Uninstall Dapr using the CLI you currently have installed. Note that this will remove the default $HOME/.dapr directory, binaries and all containers dapr_redis, dapr_placement and dapr_zipkin. Linux users need to run sudo if docker command needs sudo: 

dapr uninstall --all

For stable releases like this, download the latest and greatest release from here and put the dapr binary in your PATH.

Once you have installed the CLI, run: 

dapr init --runtime-version=1.2.0

Wait for the update to finish, ensure you are using the latest version of Dapr(1.2.0) with: 

$ dapr --version

CLI version: 1.2.0
Runtime version: 1.2.0

Kubernetes

Upgrading from previous version

You can perform zero-downtime upgrades using both Helm 3 and the Dapr CLI.

Upgrade using the CLI

Download the latest stable release from here and put the dapr binary in your PATH.

To upgrade Dapr, run: 

dapr upgrade --runtime-version 1.2.0 -k

To upgrade with high availability mode: 

dapr upgrade --runtime-version 1.2.0 --enable-ha=true -k

Wait until the operation is finished and check your status with dapr status -k.

All done!

Note: Make sure your deployments are restarted to pick the latest version of the Dapr sidecar

Upgrade using Helm

To upgrade Dapr using Helm, run: 

helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update

helm upgrade dapr dapr/dapr --version 1.2.0 --namespace=dapr-system --wait

Wait until the operation is finished and check your status with dapr status -k.

All done!

Note: Make sure your deployments are restarted to pick the latest version of the Dapr sidecar

Starting a fresh install on a cluster

Please see Deploying Dapr on a Kubernetes cluster for a complete guide to installing Dapr on Kubernetes.

You can use Helm 3 to install Dapr: 

helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update

kubectl create namespace dapr-system

helm install dapr dapr/dapr --version 1.2.0 --namespace dapr-system --wait

Alternatively, you can use the latest version of CLI: 

dapr init --runtime-version=1.2.0 -k
Post installation

Verify the control plane pods are running and are healthy: 

$ dapr status -k
  NAME                   NAMESPACE    HEALTHY  STATUS   REPLICAS  VERSION  AGE  CREATED
  dapr-dashboard         dapr-system  True     Running  1         0.6.0    15s  2021-05-20 13:07.39
  dapr-sidecar-injector  dapr-system  True     Running  1         1.2.0   15s  2021-05-20 13:07.39
  dapr-sentry            dapr-system  True     Running  1         1.2.0   15s  2021-05-20 13:07.39

  dapr-placement         dapr-system  True     Running  1         1.2.0   15s  2021-05-20 13:07.39

After Dapr 1.2.0 has been installed, perform a rolling restart for your deployments to pick up the new version of the sidecar.
This can be done with: 

kubectl rollout restart deploy/<deployment-name>
