This is the release candidate 1.0.0-rc.2

Dapr 0.11.3

Note: this hotfix is only required for the applications which uses Dapr actor building block.

Summary

Actor load tests were run to evaluate the performance and relibility. The test discovered these issues that cause memory leaks:

1. Frequent reconnections to placement service when app http endpoint is unresponsive intermitently under high load scneario
2. Memory increases from http middleware when recording request metric
3. No RSS(Resident Set Size) memory size reclaim in Kubernetes even after actors are deactivated

Regarding RSS memory size issue (bug) - Daprd stores the activated actors in a sync.Map and deletes actors when these actors are deactivated. Therefore, RSS memory for Darpd containers will be increased when actor is activated, but the memory will not be decreased even after the actors are deactivated. Users will therefore still see the same amount of RSS memory usage because Go uses MADV_FREE to free memory in linux. The memory is reclaimed only when it hits memory limit. We recommend that users consider setting dapr.io/sidecar-memory-limit and dapr.io/sidecar-memory-request to limit the size of Dapr sidecar memory usage. Please refer to this article to understand the memory usage of Go application.

Fixes

• Improve actor service health check relibility to avoid unexpected placement disconnection(#2292).
• Do not track Actor ID for actor pending lock count metric(#2295)

Dapr 0.11.2

Fixes

• Fixed remote actor invocation timeout error on Kubernetes with mTLS enabled (#2195)

Overview

The issue fixed in the 0.11.2 release had a bug that caused actors to not work on Kubernetes clusters with mTLS enabled. The root cause was the result of changes made to how Dapr uses server names when doing mutual authentication in sidecar to sidecar gRPC calls.

The server name format changed from cluster.local to <app-id>.<namespace>.cluster.local, and the actors runtime did not pass the namespace to the server name.
That led to an authentication error that was reported to the user as a gRPC timeout deadline exceeded error.

The issue was fixed with this PR.

As an immediate step, we checked why our actor e2e tests did not catch this, as this was supposed to be covered in the test.
Further investigation showed that our e2e test for actors did not use Kubernetes pod to pod invocation, which did not create a gRPC connection with the wrong server name.
An issue to fix the e2e test was opened and later completed.

Dapr 0.11.1

Fixes

• Fixed Dapr sidecar authentication issue when Highly available mode is enabled (#2187)

This is the release candidate 0.11.0-rc.2

Upgrading to Dapr 0.10.0

If you're upgrading from an older version of Dapr to 0.10.0, 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. 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 they have installed binary in default path /usr/local/bin/ or have docker command needing sudo.:

dapr uninstall --all

Next, get the latest CLI following these instructions, or alternatively download the latest and greatest release from here and put the dapr binary in your PATH.

Once you have downloaded the CLI, run:

dapr init

Wait for the update to finish, and you're good to go!
Make sure you have the right runtime version (0.10.0) with:

dapr --version

Kubernetes

Upgrading from 0.9.0

If you previously installed Dapr using Helm, starting with this releases you can now upgrade Dapr to a new version.
If you installed Dapr using the CLI, go here.

Note: For this release only, you will not be carrying your old certs over due to a breaking change in Go 1.15. To see the full documentation regarding upgrading Dapr, see here.

1. Get the latest CLI

Get the latest version of the Dapr CLI as outlined above, and put it in your path.
You can also use the helper scripts outlined here to get the latest version.

2. Upgrade

First, update your Helm repos:

helm repo update

Run the following command to upgrade Dapr:

helm upgrade dapr dapr/dapr --version 0.10.0 --namespace dapr-system --reset-values

Wait until all the pods are in Running state:

kubectl get pods -w -n dapr-system

Verify the control plane is updated and healthy:

dapr status -k

Next, issue a rolling update to your Dapr enabled deployments. When the pods restart, the new sidecar version will be picked up.

kubectl rollout restart deploy/<DEPLOYMENT-NAME>

All done!

Starting fresh

If you previously installed Dapr on your Kubernetes cluster using the Dapr CLI, run:

Note: Make sure you're uninstalling with your existing CLI

dapr uninstall --kubernetes

It's fine to ignore any errors that might show up.

If you previously installed Dapr using Helm 2.X:

helm del --purge dapr

If you previously installed Dapr using Helm 3.X:

helm uninstall dapr -n dapr-system

Update the Dapr repo:

helm repo update

If you installed Dapr with Helm to a namespace other than dapr-system, modify the uninstall command above to account for that.

You can now follow these instructions on how to install Dapr using Helm 3.

Alternatively, you can use the CLI:

dapr init --kubernetes

Post installation

Verify the control plane pods are running and are healthy:

dapr status -k

dapr-sentry            dapr-system  True     Running  0.10.0    1d   2020-08-18 10:15.21  
dapr-operator          dapr-system  True     Running  0.10.0    1d   2020-08-18 10:15.21  
dapr-sidecar-injector  dapr-system  True     Running  0.10.0    1d   2020-08-18 10:15.21  
dapr-placement         dapr-system  True     Running  0.10.0    1d   2020-08-18 10:15.21 

After Dapr 0.10.0 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>

Breaking Changes

Multi Pub/Sub

With the v0.10.0 release, we have added the support for multiple pub/sub components. That means that you can now publish and subscribe to topics arriving from different components.

To this end, several changes have been made to both the publisher and consumer sides.

Publisher

An additional parameter has been added to tell Dapr which pub/sub component you're targeting.

Old API:

POST http://localhost:<daprPort>/v1.0/publish/<topic>

New API:

POST http://localhost:<daprPort>/v1.0/publish/<pubsubname>/<topic>

Subscriber

Note: The following example in in Javascript but applicable to all languages

An additional pubsubName field has been added to the subscription payload to tell Dapr which pub/sub component this subscription is for.

Old subscription:

app.get('/dapr/subscribe', (req, res) => {
    res.json([
        {
            topic: "newOrder",
            route: "orders",
        }
    ]);
})

New subscription:

app.get('/dapr/subscribe', (req, res) => {
    res.json([
        {
            topic: "newOrder",
            route: "orders",
            pubsubName: "messagebus"
        }
    ]);
})

Changes have been made to the different SDKs, so make sure to get the latest version of the SDK you're using.
Specifically, the subscription structures have added a pubsubName field and the publish methods take the pubsubName argument.

CLI

The publish command on the Dapr CLI now takes a required param --pubsub to specifiy the pubsub component:

dapr publish --pubsub pubsub --topic myevent --data '{ "name": "yoda" }'

State retries

The retry options for state operations have been removed. If you've never used retries, this is not a breaking change.
The updated API references can be found here.

Java SDK

The Service Invocation method now accepts an HTTPExtension argument.

Old method call:

client.invokeService(serviceAppId, method, message);

New method call:

client.invokeService(serviceAppId, method, message, HttpExtension.NONE);

CLI install path

The command dapr init will now install the runtime binary daprd into $HOME/.dapr/bin for Mac/Linux and %USERPROFILE%\.dapr\ for Windows.
In addition, the --install-path argument has been removed from the dapr init and dapr uninstall commands.

Breaking Changes

Pub Sub Routes

Starting this release, topic subscribers can specify the endpoint route that Dapr should call for a given topic.

Old subscription JSON:

[
  "topic1",
  "topic2"
]

New subscription JSON:

[
  {
    "topic": "topic1",
    "route": "custom/topic1"
  },
  {
    "topic": "topic2",
    "route": "custom2/topic2"
  },
]

For more details, see here

Bi-directional bindings

Output bindings can now optionally support operations that return data to the caller.
When invoking an output binding, a new required field has been added: operation.

Old output binding JSON:

{
  "data": {
    "name": "Java the Hutt"
  }
}

New output binding JSON:

{
  "data": {
    "name": "Java the Hutt"
  },
  "operation": ""
}

100% of the current bindings support the create operation.
As new functionality is introduced to new or existing bindings, the list of supported operations can be found for each binding in the bindings spec section in the docs.

gRPC Protobuf update

You must upgrade SDKs to the latest SDK to use the latest Dapr

• Package name in Dapr gRPC protobuf files has been changed to :
  • renamed dapr.proto.dapr.v1 to dapr.proto.runtime.v1
  • renamed dapr.proto.daprclient.v1 to dapr.proto.runtime.v1
  • moved the common protobuf message related to service invocation to dapr.proto.common.v1 package

Dapr CLI publish option change

• payload option for dapr publish is changed from -p to -d.

Upgrading to Dapr 0.7.0

If you're upgrading from an older version of Dapr to 0.7.0, 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:

dapr uninstall --all

Next, get the latest CLI following these instructions, or alternatively download the latest and greatest release from here and put the dapr binary in your PATH.

Once you have downloaded the CLI, run:

dapr init

Wait for the update to finish, and you're good to go!
Make sure you have the right runtime version (0.7.0) with:

dapr --version

Kubernetes

Download the latest CLI release as outlined above in the Local Machine / Self-hosted section.

If you previously installed Dapr on your Kubernetes cluster using the Dapr CLI, run:

dapr uninstall --kubernetes

It's fine to ignore any errors that might show up.

If you previously installed Dapr using Helm 2.X:

helm del --purge dapr

If you previously installed Dapr using Helm 3.X:

helm uninstall dapr -n dapr-system

helm repo update

Wait until Dapr is uninstalled, and make sure the dapr-system namespace is gone.

If you installed Dapr with Helm to a namespace other than dapr-system, modify the uninstall command above to account for that.

You can now follow these instructions on how to install Dapr using Helm 3.

Alternatively, if you want to install Dapr in a dev/test setup, run:

dapr init --kubernetes

Post installation

After Dapr 0.7.0 has been installed, perform a rolling restart for your deployments.

Breaking Changes

gRPC Service Invocation

gRPC Protobuf update

• Package name in Dapr gRPC protobuf files has been changed to :
  • renamed to dapr to dapr.proto.dapr.v1`
  • renamed to daprclient - dapr.proto.daprclient.v1
  • moved the common protobuf message related to service invocation to dapr.proto.common.v1 package

gRPC Service invocation

• If you're a Java SDK or dotnet SDK user, you must upgrade your SDK to the latest version.
• If you're a JS/Python/CPP/Rust SDK user, you must upgrade your SDK to the latest version first and update your code by referring to each sdk's examples.
  • javascript example
  • python example
  • cpp-sdk example
  • rust-sdk example
• If HTTP callee app returns non-OK status code to caller app using gRPC API, caller app's gRPC client will throw the exception in 0.7.0 release. The caller app needs to handle the exception properly.

Tracing configuration

With the 0.7.0 release, Dapr trace configuration is simplified. Users now provide a "samplingRate" value to enable or disable the traces. Set "samplingRate: "0" to disable the traces. Set "samplingRate: "1" to generate traces on every operation. Refer https://github.com/dapr/docs/blob/master/concepts/observability/traces.md for more details.

This is the release candidate 0.7.0-rc.0

Dapr 0.6.0

We're happy to announce the release of Dapr 0.6.0!

Highlights

• Added ability to scope PubSub topics per application
• Added new components: Hazelcast PubSub, AliCloud Object storage binding, AWS Kinesis binding and GCP Pub/Sub PubSub
• Introduced new liveness/readiness probe endpoint for Dapr sidecar and actor service health API in user application
• Added mandatory TLS between the Dapr sidecar and the Dapr system services (control plane)
• Improved security by separating gRPC server for internal and external APIs
• Introduced Dapr longhaul-test app and environment
• Improved e2e test coverage and release process for manifest yaml
• Fixed major/minor bugs

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

v1.0/state/<state-store-name>/

For the latest API spec, go to this link.

Example

A call to get state prior to 0.4.0:

curl http://localhost:3500/v1.0/state/myKey

A call to get state in 0.4.0:

curl http://localhost:3500/v1.0/state/cassandra-dev/myKey
