There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.

Amazon Kendra examples using AWS CLI

The following code examples show you how to perform actions and implement common scenarios by using the AWS Command Line Interface with Amazon Kendra.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use create-data-source.

AWS CLI

To create an Amazon Kendra data source connector

The following create-data-source creates and configures an Amazon Kendra data source connector. You can use describe-data-source to view the status of a data source connector, and read any error messages if the status shows a data source connector "FAILED" to completely create.

aws kendra create-data-source \
    --name "example data source 1" \
    --description "Example data source 1 for example index 1 contains the first set of example documents" \
    --tags '{"Key": "test resources", "Value": "kendra"}, {"Key": "test resources", "Value": "aws"}' \
    --role-arn "arn:aws:iam::my-account-id:role/KendraRoleForS3TemplateConfigDataSource" \
    --index-id exampleindex1 \
    --language-code "es" \
    --schedule "0 0 18 ? * TUE,MON,WED,THU,FRI,SAT *" \
    --configuration '{"TemplateConfiguration": {"Template": file://s3schemaconfig.json}}' \
    --type "TEMPLATE" \
    --custom-document-enrichment-configuration '{"PostExtractionHookConfiguration": {"LambdaArn": "arn:aws:iam::my-account-id:function/my-function-ocr-docs", "S3Bucket": "s3://my-s3-bucket/scanned-image-text-example-docs"}, "RoleArn": "arn:aws:iam:my-account-id:role/KendraRoleForCDE"}' \
    --vpc-configuration '{"SecurityGroupIds": ["sg-1234567890abcdef0"], "SubnetIds": ["subnet-1c234","subnet-2b134"]}'

Output:

{
    "Id": "exampledatasource1"
}

The following code example shows how to use create-index.

AWS CLI

To create an Amazon Kendra index

The following create-index creates and configures an Amazon Kendra index. You can use describe-index to view the status of an index, and read any error messages if the status shows an index "FAILED" to completely create.

aws kendra create-index \
    --name "example index 1" \
    --description "Example index 1 contains the first set of example documents" \
    --tags '{"Key": "test resources", "Value": "kendra"}, {"Key": "test resources", "Value": "aws"}' \
    --role-arn "arn:aws:iam::my-account-id:role/KendraRoleForExampleIndex" \
    --edition "DEVELOPER_EDITION" \
    --server-side-encryption-configuration '{"KmsKeyId": "my-kms-key-id"}' \
    --user-context-policy "USER_TOKEN" \
    --user-token-configurations '{"JsonTokenTypeConfiguration": {"GroupAttributeField": "groupNameField", "UserNameAttributeField": "userNameField"}}'

Output:

{
   "Id": index1
}

The following code example shows how to use update-data-source.

AWS CLI

To update an Amazon Kendra data source connector

The following update-data-source updates the configuration of an Amazon Kendra data source connector. If the action is successful, the service either sends back no output, the HTTP status code 200, or the AWS CLI return code 0. You can use describe-data-source to view the configuration and status of a data source connector.

aws kendra update-data-source \
    --id exampledatasource1 \
    --index-id exampleindex1 \
    --name "new name for example data source 1" \
    --description "new description for example data source 1" \
