16장. AWS S3 Source
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 are duplicated with different names for clarity at sink level. CamelAwsS3Key is duplicated into aws.s3.key and CamelAwsS3BucketName is duplicated in aws.s3.bucket.name.
16.1. Authentication methods
In this Kamelet you can avoid using explicit static credentials by specifying the useDefaultCredentialsProvider option and set it to true.
The order of evaluation for Default Credentials Provider is the following:
-
Java system properties -
aws.accessKeyIdandaws.secretKey. -
Environment variables -
AWS_ACCESS_KEY_IDandAWS_SECRET_ACCESS_KEY. - Web Identity Token from AWS STS.
- The shared credentials and config files.
-
Amazon ECS container credentials - loaded from the Amazon ECS if the environment variable
AWS_CONTAINER_CREDENTIALS_RELATIVE_URIis set. - Amazon EC2 Instance profile credentials.
You can also use the Profile Credentials Provider, by setting the useProfileCredentialsProvider option to true and profileCredentialsName to the profile name.
Only one of access key/secret key or default credentials provider could be used
