Component format

To setup AWS S3 binding create a component of type bindings.aws.s3. See [this guide]({{< ref "howto-bindings.md#1-create-a-binding" >}}) on how to create and apply a binding configuration.

See [Authenticating to AWS]({{< ref authenticating-aws.md >}}) for information about authentication-related attributes

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: bindings.aws.s3
  version: v1
  metadata:
  - name: bucket
    value: mybucket
  - name: region
    value: us-west-2
  - name: accessKey
    value: *****************
  - name: secretKey
    value: *****************
  - name: sessionToken
    value: mysession

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}

Spec metadata fields

Field	Required	Binding support	Details	Example
bucket	Y	Output	The name of the S3 bucket to write to	`"bucket"`
region	Y	Output	The specific AWS region	`"us-east-1"`
accessKey	Y	Output	The AWS Access Key to access this resource	`"key"`
secretKey	Y	Output	The AWS Secret Access Key to access this resource	`"secretAccessKey"`
sessionToken	N	Output	The AWS session token to use	`"sessionToken"`

Binding support

This component supports output binding with the following operations:

create

Create file

To perform a create operation, invoke the AWS S3 binding with a POST method and the following JSON body:

Note: by default, a random UUID is generated. See below for Metadata support to set the name

{
  "operation": "create",
  "data": "YOUR_CONTENT"
}

Examples

Save text to a random generated UUID file

{{< tabs Windows Linux >}} {{% codetab %}} On Windows, utilize cmd prompt (PowerShell has different escaping mechanism)

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\" }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World" }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

Save text to a specific file

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\", \"metadata\": { \"key\": \"my-test-file.txt\" } }" \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World", "metadata": { "key": "my-test-file.txt" } }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

Upload a file

To upload a file, pass the file contents as the data payload; you may want to encode this in e.g. Base64 for binary content.

Then you can upload it as you would normally:

curl -d "{ \"operation\": \"create\", \"data\": \"(YOUR_FILE_CONTENTS)\", \"metadata\": { \"key\": \"my-test-file.jpg\" } }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "$(cat my-test-file.jpg)", "metadata": { "key": "my-test-file.jpg" } }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>
