Sync rules

edit

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

Advanced sync rules
edit

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 key
edit
[
  {
    "repository": "repo_name",
    "filter": {
      "branch": "sync-rules-feature"
    }
  }
]
Indexing document based on issue query related to bugs via issue key
edit
[
  {
    "repository": "repo_name",
    "filter": {
      "issue": "is:bug"
    }
  }
]
Indexing document based on PR query related to open PR’s via PR key
edit
[
  {
    "repository": "repo_name",
    "filter": {
      "pr": "is:open"
    }
  }
]
Indexing document and files based on queries and branch name
edit
[
  {
    "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 overlapping
edit
[
  {
    "filter": {
      "pr": "is:pr is:merged label:auto-backport merged:>=2023-07-20"
    },
    "repository": "repo_name"
  },
  {
    "filter": {
      "pr": "is:pr is:merged label:auto-backport merged:>=2023-07-15"
    },
    "repository": "repo_name"
  }
]

Connector client (self-managed)

edit
View connector client reference

Availability and prerequisites

edit

This connector is available as a self-managed connector client.

This connector client is compatible with Elastic versions 8.10.0+.

To use this connector, satisfy all connector client requirements.

Usage

edit

Self-manage this connector

Because this client is available as a native connector, you’ll first need to convert to a connector client in the Kibana UI. This action is irreversible. Use the Convert connector button on the right-hand side of the configuration page.

To use this connector as a connector client, see Connector clients.

For additional usage operations, see Using connectors.

GitHub access token

Configure a GitHub access token to fetch data from GitHub.

Follow these steps to generate a GitHub access token:

  • Go to GitHub Settings → Developer settings → Personal access tokens → Tokens(classic).
  • Select Generate new token.
  • Add a note and select the "repo" scope.
  • Select Generate token and copy the token.

Compatibility

edit

Both GitHub and GitHub Enterprise are supported.

Configuration

edit

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.
repositories

Comma-separated list of repositories to fetch data from GitHub instance. If the value is * the connector will fetch data from all repositories present in the configured user’s account.

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-----
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 Docker

edit

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>

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:8.11.4.0 \
/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.
