aws-data-exchange-publisher-coordinator

This package sets up Lambdas (via CloudFormation) to automatically execute the publication steps for new dataset revisions. Execution is triggered when an S3 manifest file for a new revision is uploaded to this bucket.

Prerequisites

Read the AWS Data Exchange Publisher Coordinator doc which describes the architecture of the solution and prerequisites.
You should have:

1. AWS Data Exchange product and data set created.
2. Three existing S3 buckets:
   • AssetBucket: For uploading the assets
   • ManifestBucketLoggingBucket: For logging activities
   • DistributionBucket: For uploading the Lambda codes.
3. Python 3.8+
4. AWS CLI
5. AWS SAM CLI (separate from above)

Modify the CloudFormation template with your bucket names

• Clone the repository, and update the below four S3 buckets in template.yaml.
• In the template snippet below, the ManifestBucket parameter sets the name of the bucket to be created by Cloudformation. The other two bucket names are from the preexisting buckets above.
• Create a local folder in the project directory to store the Cloudformation template output created by SAM build.

Parameters:
  ManifestBucket:
    Type: String
    Default: 'my-test-manifest-bucket' // Name of the new bucket that will be created in this solution
    Description: S3 Bucket name where .manifest files will be stored
  AssetBucket:
    Type: String
    Default: 'my-asset-bucket-publisher-test' // Name of the existing bucket where new assets are added 
    Description: Bucket containing assets and referenced in the manifest.  
  ManifestBucketLoggingBucket:
    Type: String
    Default: 'my-test-manifest-logging-bucket' // Name of the existing bucket where activity logs will be saved
    Description: Bucket to store server access logs associated with the manifest bucket
  ManifestBucketLoggingPrefix:
    Type: String
    Default: 'my-publisher-coordinator-logs/' // Prefix string (including the trailing slash)
    Description: Prefix location for server access logs associated with the manifest bucket

Building Cloudformation template with customization

• Set environment variables:

export CFN_CODE_BUCKET=my-bucket-name # bucket where customized code will reside
export SOLUTION_NAME=my-solution-name
export VERSION=my-version # version number for the customized code

Note: It is recommended to include the aws region in your bucket name, e.g. my-bucket-name-<aws_region>. Also, the assets in bucket should be publicly accessible.

• Now package the Lambda codes for upload:

chmod +x ./package-codes-for-upload.sh
./package-codes-for-upload.sh $CFN_CODE_BUCKET $SOLUTION_NAME $VERSION

• Upload the code to the $CFN_CODE_BUCKET S3 bucket in your account using the AWS CLI.

aws s3 cp ./global-s3-assets s3://$CFN_CODE_BUCKET/$SOLUTION_NAME/$VERSION/ \
    --recursive --acl bucket-owner-full-control
aws s3 cp ./regional-s3-assets s3://$CFN_CODE_BUCKET/$SOLUTION_NAME/$VERSION/ \
    --recursive --acl bucket-owner-full-control

• Use AWS SAM to build and deploy the Cloudformation template:

cd source
sam build
sam package --s3-bucket $CFN_CODE_BUCKET \
     --output-template ../local/aws-data-exchange-publisher-coordinator-SAM.template
sam deploy --template-file ../local/aws-data-exchange-publisher-coordinator-SAM.template \
    --region <Region> --stack-name <StackName> --capabilities CAPABILITY_IAM
