Upgrading to Dapr 0.9.0
If you're upgrading from an older version of Dapr to 0.9.0, 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 .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 --allNext, 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 initWait for the update to finish, and you're good to go!
Make sure you have the right runtime version (0.9.0) with:
dapr --versionKubernetes
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 --kubernetesIt's fine to ignore any errors that might show up.
If you previously installed Dapr using Helm 2.X:
helm del --purge daprIf you previously installed Dapr using Helm 3.X:
helm uninstall dapr -n dapr-systemUpdate the Dapr repo:
helm repo updateIf 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 0.9.0 has been installed, perform a rolling restart for your deployments.
Breaking Changes
Standalone dapr init and uninstall behavior
- dapr uninstall --all now removes the default .dapr directory and binaries
- dapr init fails if a previous version is installed. You will need to run dapr uninstall first.
- dapr init now deploys a local Zipkin container by default for use with local diagnostic testing.
Dapr init behavior to create default component files
- The default component files are now created during dapr init time.
Cosmos DB partition key setup and usage
The name of the required partition key has changed from /id to /partitionKey. Please see this for more details.
