Elastic S3 connector reference
editElastic S3 connector reference
editThe Elastic S3 connector is a connector for Amazon S3 data sources.
Native connector reference (managed service)
editView reference for the native connector reference (managed service).
Availability and prerequisites
editThis connector is available natively in Elastic Cloud as of version 8.12.0. To use this connector, satisfy all native connector requirements.
Create a Amazon S3 connector
editUse the UI
editTo create a new Amazon S3 connector:
- Navigate to the Search → Connectors page in the Kibana UI.
- Follow the instructions to create a new native Amazon S3 connector.
For additional operations, see Using connectors.
Use the API
editYou can use the elasticsearch Create connector API to create a new native Amazon S3 connector.
For example:
PUT _connector/<my-s3-connector> { "index_name": "<my-elasticsearch-index>", "name": "Content synced from Amazon S3", "service_type": "s3", "is_native": "true" }
You’ll also need to create an API key for the connector to use.
The user needs the cluster privileges manage_api_key
, manage_connector
and write_connector_secrets
to generate API keys programmatically.
To create an API key for the connector:
-
Run the following command, replacing values where indicated. Note the
id
andencoded
return values from the response:POST /_security/api_key { "name": "<connector_name>-connector-api-key", "role_descriptors": { "<connector_name>-connector-role": { "cluster": [ "monitor", "manage_connector" ], "indices": [ { "names": [ "<index_name>", ".search-acl-filter-<index_name>", ".elastic-connectors*" ], "privileges": [ "all" ], "allow_restricted_indices": false } ] } } }
-
Use the
encoded
value to store a connector secret, and note theid
return value from this response:POST _connector/_secret { "value": <encoded_api_key> }
-
Use the API key
id
and the connector secretid
to update the connector:PUT /_connector/<connector_id>/_api_key_id { "api_key_id": "<API key id>", "api_key_secret_id": "<secret id>" }
Refer to the elasticsearch API documentation for details of all available Connector APIs.
Usage
editTo use this native connector, see Native connectors (managed service).
For additional operations, see Using connectors.
S3 users will also need to Create an IAM identity
Create an IAM identity
editUsers need to create an IAM identity to use this connector as a connector client. Refer to the AWS documentation.
The policy associated with the IAM identity must have the following AWS permissions:
-
ListAllMyBuckets
-
ListBucket
-
GetBucketLocation
-
GetObject
Compatibility
editCurrently the connector does not support S3-compatible vendors.
Configuration
editThe following configuration fields are required to set up the connector:
- AWS Buckets
-
List of S3 bucket names.
*
will fetch data from all buckets. Examples:-
testbucket, prodbucket
-
testbucket
-
*
-
This field is ignored when using advanced sync rules.
- AWS Access Key ID
- Access Key ID for the AWS identity that will be used for bucket access.
- AWS Secret Key
- Secret Access Key for the AWS identity that will be used for bucket access.
Documents and syncs
edit- Content from files bigger than 10 MB won’t be extracted. (Self-managed connectors can use the self-managed local extraction service to handle larger binary files.)
- Permissions are not synced. All documents indexed to an Elastic deployment will be visible to all users with access to that Elastic Deployment.
Sync rules
editBasic sync rules are identical for all connectors and are available by default.
Advanced sync rules
editA full sync is required for advanced sync rules to take effect.
Advanced sync rules are defined through a source-specific DSL JSON snippet.
Use advanced sync rules to filter data to be fetched from Amazon S3 buckets. They take the following parameters:
-
bucket
: S3 bucket the rule applies to. -
extension
(optional): Lists which file types to sync. Defaults to syncing all types. -
prefix
(optional): String of prefix characters. The connector will fetch file and folder data that matches the string. Defaults to""
(syncs all bucket objects).
Advanced sync rules examples
editFetching files and folders recursively by prefix
Example: Fetch files/folders in folder1/docs
.
[ { "bucket": "bucket1", "prefix": "folder1/docs" } ]
Example: Fetch files/folder starting with folder1
.
[ { "bucket": "bucket2", "prefix": "folder1" } ]
Fetching files and folders by specifying extensions
Example: Fetch all objects which start with abc
and then filter using file extensions.
[ { "bucket": "bucket2", "prefix": "abc", "extension": [".txt", ".png"] } ]

Deployment using Docker
editYou can deploy the Amazon S3 connector as a self-managed connector client using Docker. Follow these instructions.
Step 1: Download sample configuration file
Download the sample configuration file. You can either download it manually or run the following command:
curl https://raw.githubusercontent.com/elastic/connectors/main/config.yml.example --output ~/connectors-config/config.yml
Remember to update the --output
argument value if your directory name is different, or you want to use a different config file name.
Step 2: Update the configuration file for your self-managed connector
Update the configuration file with the following settings to match your environment:
-
elasticsearch.host
-
elasticsearch.api_key
-
connectors
If you’re running the connector service against a Dockerized version of elasticsearch and Kibana, your config file will look like this:
# When connecting to your cloud deployment you should edit the host value elasticsearch.host: http://host.docker.internal:9200 elasticsearch.api_key: <elasticsearch_API_KEY> connectors: - connector_id: <CONNECTOR_ID_FROM_KIBANA> service_type: s3 api_key: <CONNECTOR_API_KEY_FROM_KIBANA> # Optional. If not provided, the connector will use the elasticsearch.api_key instead
Using the elasticsearch.api_key
is the recommended authentication method. However, you can also use elasticsearch.username
and elasticsearch.password
to authenticate with your elasticsearch instance.
Note: You can change other default configurations by simply uncommenting specific settings in the configuration file and modifying their values.
Step 3: Run the Docker image
Run the Docker image with the Connector Service using the following command:
docker run \ -v ~/connectors-config:/config \ --network "elastic" \ --tty \ --rm \ docker.elastic.co/enterprise-search/elastic-connectors:8.15.3.0 \ /app/bin/elastic-ingest \ -c /config/config.yml
Refer to DOCKER.md
in the elastic/connectors
repo for more details.
Find all available Docker images in the official registry.
We also have a quickstart self-managed option using Docker Compose, so you can spin up all required services at once: elasticsearch, Kibana, and the connectors service.
Refer to this README in the elastic/connectors
repo for more information.

Content extraction
editSee Content extraction.
End-to-end testing
editThe connector framework enables operators to run functional tests against a real data source. Refer to Connector testing for more details.
To execute a functional test for the Amazon S3 connector client, run the following command:
make ftest NAME=s3
By default, this will use a medium-sized dataset.
To make the test faster add the DATA_SIZE=small
argument:
make ftest NAME=s3 DATA_SIZE=small
