AWS S3 Source

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Receive data from an Amazon S3 Bucket.

The basic authentication method for the S3 service is to specify an access key and a secret key. These parameters are optional because the Kamelet provides a default credentials provider.

If you use the default credentials provider, the S3 client loads the credentials through this provider and doesn’t use the basic authentication method.

Two headers will be duplicated with different names for clarity at sink level, CamelAwsS3Key will be duplicated into aws.s3.key and CamelAwsS3BucketName will be duplicated in aws.s3.bucket.name

Dependencies

At runtime, the aws-s3-source Kamelet relies upon the presence of the following dependencies:

camel:core
camel:aws2-s3
mvn:org.apache.camel.kamelets:camel-kamelets-utils:4.0.4-SNAPSHOT
camel:kamelet

Camel JBang usage

Prerequisites

You’ve installed JBang.
You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml

Camel K Environment Usage

This section describes how you can use the aws-s3-source.

Knative source

You can use the aws-s3-source Kamelet as a Knative source by binding it to a Knative object.

aws-s3-source-binding.yaml

apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: aws-s3-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: aws-s3-source
    properties:
      bucketNameOrArn: The Bucket Name
      region: The AWS Region
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

Save the aws-s3-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.
Run the source by using the following command:
```
kubectl apply -f aws-s3-source-binding.yaml
```

Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind channel:mychannel -p "source.bucketNameOrArn=The Bucket Name" -p "source.region=The AWS Region" aws-s3-source

This command creates the KameletBinding in the current namespace on the cluster.

Kafka source

You can use the aws-s3-source Kamelet as a Kafka source by binding it to a Kafka topic.

aws-s3-source-binding.yaml

apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: aws-s3-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: aws-s3-source
    properties:
      bucketNameOrArn: The Bucket Name
      region: The AWS Region
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

Prerequisites

You’ve installed Strimzi.
You’ve created a topic named my-topic in the current namespace.
You have Camel K installed on the cluster.

Procedure for using the cluster CLI

Save the aws-s3-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.
Run the source by using the following command:
```
kubectl apply -f aws-s3-source-binding.yaml
```

Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic -p "source.bucketNameOrArn=The Bucket Name" -p "source.region=The AWS Region" aws-s3-source

This command creates the KameletBinding in the current namespace on the cluster.
