# Amazon Kinesis Data Streams The Amazon Kinesis Data Streams output plugin lets you ingest your records into the [Kinesis](https://aws.amazon.com/kinesis/data-streams/) service. This is the documentation for the core Fluent Bit Kinesis plugin written in C. It has all the core features of the [aws/amazon-kinesis-streams-for-fluent-bit](https://github.com/aws/amazon-kinesis-streams-for-fluent-bit) Golang Fluent Bit plugin released in 2019. The original Golang plugin is named `kinesis`, and this new high performance and highly efficient Kinesis plugin is called `kinesis_streams` to prevent conflicts or confusion. This `kinesis_streams` plugin always uses a random partition key when uploading records to Kinesis through the [PutRecords API](https://docs.aws.amazon.com/kinesis/latest/APIReference/API_PutRecords.html). For information about how AWS credentials are fetched, see [AWS credentials](https://docs.fluentbit.io/manual/4.1/administration/aws-credentials). ## Configuration parameters | Key | Description | Default | | --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------- | | `region` | The AWS region. | *none* | | `stream` | The name of the Kinesis Streams Delivery stream that you want log records sent to. | *none* | | `time_key` | Add the timestamp to the record under this key. | `false` | | `time_key_format` | The strftime compliant format string for the timestamp. Supports millisecond precision with `%3N` and supports nanosecond precision with `%9N` and `%L`. For example, adding `%3N` to support millisecond `%Y-%m-%dT%H:%M:%S.%3N`. This option is used with `time_key`. | `%Y-%m-%dT%H:%M:%S` | | `log_key` | By default, the whole log record will be sent to Kinesis. If you specify a key name with this option, then only the value of that key will be sent to Kinesis. For example, if you are using the Fluentd Docker log driver, you can specify `log_key log` and only the log message will be sent to Kinesis. | *none* | | `role_arn` | ARN of an IAM role to assume (for cross account access). | *none* | | `endpoint` | Specify a custom endpoint for the Kinesis API. | *none* | | `port` | TCP port of the Kinesis Streams service. | `443` | | `sts_endpoint` | Custom endpoint for the STS API. | *none* | | `auto_retry_requests` | Immediately retry failed requests to AWS services once. This option doesn't affect the normal Fluent Bit retry mechanism with backoff. Instead, it enables an immediate retry with no delay for networking errors, which might help improve throughput when there are transient/random networking issues. | `true` | | `external_id` | Specify an external ID for the STS API, can be used with the `role_arn` parameter if your role requires an external ID. | *none* | | `profile` | AWS profile name to use. | `default` | | `workers` | The number of [workers](https://docs.fluentbit.io/manual/4.1/administration/multithreading#outputs) to perform flush operations for this output. | `1` | ## Get started To send records into Amazon Kinesis Data Streams, you can run the plugin from the command line or through the configuration file. ### Command line The `kinesis_streams` plugin can read the parameters from the command line through the `-p` (property) argument. For example: ```shell fluent-bit -i cpu -o kinesis_streams -p stream=my-stream -p region=us-west-2 -m '*' -f 1 ``` ### Configuration file In your main configuration file append the following: {% tabs %} {% tab title="fluent-bit.yaml" %} ```yaml pipeline: outputs: - name: kinesis_streams match: '*' region: us-east-1 stream: my-stream ``` {% endtab %} {% tab title="fluent-bit.conf" %} ``` [OUTPUT] Name kinesis_streams Match * region us-east-1 stream my-stream ``` {% endtab %} {% endtabs %} ### Permissions The following AWS IAM permissions are required to use this plugin: ```json { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": [ "kinesis:PutRecords" ], "Resource": "*" }] } ``` ## Container images Amazon distributes a container image with Fluent Bit and these plugins. ### GitHub The [aws-for-fluent-bit](https://github.com/aws/aws-for-fluent-bit) container image is available on GitHub. ### Amazon ECR Public Gallery The [aws-for-fluent-bit](https://gallery.ecr.aws/aws-observability/aws-for-fluent-bit) container image is available on the Amazon ECR Public Gallery. Use the following command to download images with different tags: ```shell docker pull public.ecr.aws/aws-observability/aws-for-fluent-bit:TAG ``` Replace `TAG` with the tag of the image you want to download. You can also use the value `latest` to download the latest image. If you see errors for image pull limits, try to log into the gallery with your AWS credentials: ```shell aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws ``` You can use the Fluent Bit SSM Public Parameters to find the Amazon ECR image URI in your region: ```shell aws ssm get-parameters-by-path --path /aws/service/aws-for-fluent-bit/ ``` For more details, see the [Amazon ECR Public official doc](https://docs.aws.amazon.com/AmazonECR/latest/public/get-set-up-for-amazon-ecr.html). ### Docker Hub The [aws-for-fluent-bit](https://hub.docker.com/r/amazon/aws-for-fluent-bit/tags) container image is available on Docker Hub. ### More information For more information, see the [aws-for-fluent-bit README](https://github.com/aws/aws-for-fluent-bit#public-images) on GitHub.
