The documentation you are viewing is for Dapr v1.7 which is an older version of Dapr. For up-to-date documentation, see the latest version.
Dapr integrates with external resources to allow apps to both be triggered by external events and interact with the resources. Each binding component has a name and this name is used when interacting with the resource.
As with other building block components, binding components are extensible and can be found in the components-contrib repo.
A binding in Dapr is described using a
Component file with the following fields:
apiVersion: dapr.io/v1alpha1 kind: Component metadata: name: <NAME> namespace: <NAMESPACE> spec: type: bindings.<NAME> version: v1 metadata: - name: <KEY> value: <VALUE> - name: <KEY> value: <VALUE> ...
The type of binding is determined by the
type field, and things like connection strings and other metadata are put in the
apiVersion: dapr.io/v1alpha1 kind: Component metadata: name: <NAME> namespace: <NAMESPACE> spec: type: bindings.azure.blobstorage version: v1 metadata: - name: storageAccount value: myStorageAccountName - name: storageAccessKey value: *********** - name: container value: container1 - name: decodeBase64 value: <bool> - name: getBlobRetryCount value: <integer>
Apply the configuration
Once you have created the component’s YAML file, follow these instructions to apply it based on your hosting environment:
To run locally, create a
components dir containing the YAML file and provide the path to the
dapr run command with the flag
To deploy in Kubernetes, assuming your component file is named
kubectl apply -f mybinding.yaml
