Native connector (Elastic Cloud)edit

View native connector reference

Availability and prerequisitesedit

This connector is available as a native connector as of Elastic version 8.11.0.

To use this connector natively in Elastic Cloud, satisfy all native connector requirements.

Create a GitHub connectoredit

Use the UIedit

To create a new GitHub connector:

Navigate to the Search → Connectors page in the Kibana UI.
Follow the instructions to create a new native GitHub connector.

For additional operations, see Using connectors.

Use the APIedit

You can use the Elasticsearch Create connector API to create a new native GitHub connector.

For example:

PUT _connector/<my-github-connector>
{
  "index_name": "<my-elasticsearch-index>",
  "name": "Content synced from GitHub",
  "service_type": "github",
  "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 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 and encoded return values from the response:

POST /_security/api_key
{
  "name": "<connector_name>-connector-api-key",
  "role_descriptors": {
    "<connector_name>-connector-role": {
      "cluster": [
        "monitor"
      ],
      "indices": [
        {
          "names": [
            "<index_name>",
            ".search-acl-filter-<index_name>",
            ".elastic-connectors-v1*"
          ],
          "privileges": [
            "all"
          ],
          "allow_restricted_indices": false
        }
      ]
    }
  }
}

Use the encoded value to store a connector secret, and note the id return value from this response:
```
POST _connector/_secret
{
  "value": <encoded_api_key>
}
```

Use the API key id and the connector secret id 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.

Usageedit

To use this connector as a native connector, see Native connectors (managed service).

For additional operations, see Using connectors.

-----END CERTIFICATE-----

Enable document level security

Toggle to enable document level security (DLS). When enabled, full syncs will fetch access control lists for each document and store them in the _allow_access_control field. DLS is only available when Repository Type is set to Organization.

Documents and syncsedit

The connector syncs the following objects and entities:

Repositories
Pull Requests
Issues
Files & Folder

Only the following file extensions are ingested:

.markdown
.md
.rst

Content of files bigger than 10 MB won’t be extracted.
Permissions are not synced. All documents indexed to an Elastic deployment will be visible to all users with access to that Elasticsearch Index.

Sync typesedit

Full syncs are supported by default for all connectors.

This connector also supports incremental syncs, but this feature is currently disabled by default. Refer to the linked documentation for enabling incremental syncs.

Sync rulesedit

Basic sync rules are identical for all connectors and are available by default. For more information read Types of sync rule.

Advanced sync rulesedit

A full sync is required for advanced sync rules to take effect.

The following section describes advanced sync rules for this connector. Advanced sync rules are defined through a source-specific DSL JSON snippet.

The following sections provide examples of advanced sync rules for this connector.

Indexing document and files based on branch name configured via branch keyedit

[
  {
    "repository": "repo_name",
    "filter": {
      "branch": "sync-rules-feature"
    }
  }
]

Indexing document based on issue query related to bugs via issue keyedit

[
  {
    "repository": "repo_name",
    "filter": {
      "issue": "is:bug"
    }
  }
]

Indexing document based on PR query related to open PR’s via PR keyedit

[
  {
    "repository": "repo_name",
    "filter": {
      "pr": "is:open"
    }
  }
]

Indexing document and files based on queries and branch nameedit

[
  {
    "repository": "repo_name",
    "filter": {
      "issue": "is:bug",
      "pr": "is:open",
      "branch": "sync-rules-feature"
    }
  }
]

All documents pulled by a given rule are indexed regardless of whether the document has already been indexed by a previous rule. This can lead to document duplication, but the indexed documents count will differ in the logs. Check the Elasticsearch index for the actual document count.

Advanced rules for overlappingedit

[
  {
    "filter": {
      "pr": "is:pr is:merged label:auto-backport merged:>=2023-07-20"
    },
    "repository": "repo_name"
  },
  {
    "filter": {

When using the build a connector workflow, initially these fields will use the default configuration set in the connector source code. These are set in the get_default_configuration function definition.

These configurable fields will be rendered with their respective labels in the Kibana UI. Once connected, you’ll be able to update these values in Kibana.

The following configuration fields are required:

data source

GitHub Cloud or GitHub Server.

host

URL of the GitHub Server instance. (GitHub Server only)

github_token

GitHub access token to authenticate the GitHub instance.

repo_type

Toggle between Organization and Other. Note that document level security (DLS) is only available for Organization repositories.

Default value is *.

Examples:

elasticsearch,elastic/kibana
*

Repository ownership

If the "OWNER/" portion of the "OWNER/REPO" repository argument is omitted, it defaults to the name of the authenticating user.

In the examples provided here:

the elasticsearch repo synced will be the <OWNER>/elasticsearch
the kibana repo synced will be the Elastic owned repo

This field can be bypassed by advanced sync rules.

ssl_enabled

Whether SSL verification will be enabled. Default value is False.

ssl_ca

Content of SSL certificate. Note: If ssl_enabled is False, the value in this field is ignored. Example certificate:

-----BEGIN CERTIFICATE-----
MIID+jCCAuKgAwIBAgIGAJJMzlxLMA0GCSqGSIb3DQEBCwUAMHoxCzAJBgNVBAYT
...
7RhLQyWn2u00L7/9Omw=
-----END CERTIFICATE-----

use_document_level_security

retry_count

The number of retry attempts after failed request to GitHub. Default value is 3.

use_text_extraction_service

Requires a separate deployment of the Elastic Text Extraction Service. Requires that pipeline settings disable text extraction. Default value is False.

Deployment using Dockeredit

You can deploy the GitHub 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: github
    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:8.13.2.0 \
/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.

Documents and syncsedit

The connector syncs the following objects and entities:

Repositories
Pull Requests
Issues
