Amazon S3 is an object storage service that gives scalability and availability the place you may retailer massive quantities of information, together with product manuals, challenge and analysis paperwork, and extra.

On this submit, you may discover ways to deploy a offered AWS CloudFormation template to index your paperwork in an Amazon S3 bucket. The template creates an Amazon Kendra knowledge supply for an index and synchronizes your knowledge supply in keeping with your wants: on-demand, hourly, each day, weekly or month-to-month. AWS CloudFormation permits us to provision infrastructure as code (IaC) so you may spend much less time managing sources, replicate your infrastructure rapidly, and management and monitor adjustments within the infrastructure.

Overview of the answer

The CloudFormation template units up an Amazon Kendra knowledge supply with a connection to Amazon S3. The template additionally creates one position for the Amazon Kendra knowledge supply service. You may specify an S3 bucket, synchronization schedule, and inclusion/exclusion patterns. When the synchronization job has completed, you may search the listed content material via the Search console. The next diagram illustrates this workflow.

This submit guides you to the next steps:

  1. Deploy the offered template.
  2. Add the paperwork to the S3 bucket that you just create. In case you present a bucket with paperwork, you may omit this step.
  3. Wait till the index finishes crawling the information supply.


For this walkthrough, it is best to have the next conditions:

  • An AWS account the place the proposed resolution may be deployed.
  • An Amazon Kendra index for attaching a knowledge supply to the stack.
  • The set of paperwork which are used to create the Amazon Kendra index. On this resolution, you might be utilizing a compressed file of AWS whitepapers.

Deploy the answer with AWS CloudFormation

To deploy the CloudFormation template, full the next steps:

  1. Select

You’re redirected to the AWS CloudFormation console.

  1. You may modify the parameters or use the default values:
    • The Amazon Kendra knowledge supply identify is robotically set utilizing the stack identify and related bucket identify.
    • For KendraIndexId, enter the Amazon Kendra index ID the place you’ll connect the information supply.
    • You too can select while you need to run the information supply synchronization utilizing KendraSyncSchedule. By default, it’s set to OnDemand.
    • For S3BucketName, you may both enter a bucket you could have already created or depart it empty. In case you depart it empty, a bucket shall be created for you. Both means, the bucket is used because the Amazon Kendra knowledge supply. For this submit, we depart it empty.

It takes round 5 minutes for the stack to deploy the Amazon Kendra knowledge supply connected to the Amazon Kendra index.

  1. On the Outputs tab of the CloudFormation stack, copy the identify of the created bucket, knowledge supply identify, and ID.

The created stack deploys one position: <stack-name>-KendraDataSourceRole. It’s a greatest observe to deploy a task for every knowledge supply you create. This position provides Amazon Kendra knowledge supply so as to add or take away recordsdata from Amazon Kendra index, to get objects from Amazon S3 bucket.

Add recordsdata to the S3 bucket

Amazon Kendra can deal with a number of doc sorts, equivalent to .html, .pdf, .csv, .json, .docx, and .ppt. You too can have a mixture of paperwork on a single index. The textual content contained in these paperwork is listed to the offered Amazon Kendra index. You may seek for key phrases on AWS matters on greatest practices, databases, machine studying, safety, and extra utilizing over 60 pdf recordsdata that you could download. For instance, if you wish to know the place you could find extra details about caching within the AWS whitepapers, Amazon Kendra will help you discover paperwork associated to databases and greatest practices.

While you obtain the AWS Whitepapers.zip file and uncompress the file, you see these six folders: Best_Practices, Databases, Normal, Machine_Learning, Safety, Well_Architected. Add these folders to your S3 bucket.

Synchronize the Amazon Kendra knowledge supply

Amazon Kendra knowledge supply knowledge can synchronize your knowledge primarily based on preconfigured schedule or may be be manually triggered on-demand. By default, CloudFormation template configures the information supply to on-demand synchronization schedule to be triggered manually as required.

To manually set off the synchronization job from the AWS Amazon Kendra console, navigate to the Amazon Kendra index used as a part of CloudFormation stack deployment, underneath Information Administration within the navigation pane, select Information Sources after which select Sync now. This makes the S3 bucket synchronize with the information supply.

When the Amazon Kendra knowledge supply begins syncing, it is best to see the Present sync state as Syncing.

When the information supply has completed, the Final sync standing seems as Succeeded and Present sync state as Idle. Now you can search the listed content material.

Configure synchronization schedule

The template permits you to run the schedule each hour at minute 0, for instance, 13:00, 14:00, or 15:00. You even have the choice to run it each day at 00:00 UTC. The Weekly setting runs Mondays at 00:00 UTC, and the Month-to-month setting runs each first day of the month at 00:00 UTC.

To alter the schedule after the Amazon Kendra knowledge supply has been created, on the Actions menu, select Edit. Below Configure sync settings, you discover the Sync rule schedule part.

Below Frequency, you may choose hourly, each day, weekly, month-to-month, or customized, all of which let you schedule your sync right down to the minute.

Add exclusion patterns

The offered CloudFormation template permits you to add exclusion patterns. By default, .png and .jpg recordsdata shall be added to the ExclusionPatterns parameter. Extra file codecs may be added as a comma separated record to the exclusion sample. Equally, InclusionPatterns parameter could also be used add comma record file codecs to arrange an inclusion sample. In case you don’t present an inclusion sample, all recordsdata are listed aside from those included within the exclusion parameter.

Clear up

To keep away from prices, you may delete the stack from the AWS CloudFormation console. On the Stacks web page, choose the stack you created, select Delete, and make sure the deletion of the stack.

In case you haven’t offered a S3 bucket, the stack creates a bucket. If the bucket is empty, it’s robotically deleted. In any other case, it is advisable to empty the folder and manually delete it. In case you offered a bucket, even when it’s empty, it received’t be deleted. Amazon Kendra index received’t be deleted. Solely the Amazon Kendra knowledge supply created by the stack shall be deleted.


On this submit, we offered an CloudFormation template to simply synchronize your textual content paperwork on an S3 bucket to your Amazon Kendra index. This resolution is useful in case you have a number of S3 buckets you need to index as a result of you may create all the mandatory elements to question the paperwork with a couple of clicks in a constant and repeatable method. You too can see how image-based textual content paperwork may be dealt with in Amazon Kendra. To be taught extra about particular schedule patterns, confer with Schedule Expressions for Rules.

Go away a remark and be taught extra about Amazon Kendra index creation within the following Amazon Kendra Essentials+ workshop.

Particular due to Jose Mauricio Mani Yanez for his assist creating the instance code and compiling the content material for this submit.
