This module enables storing SilverStripe sessions in DynamoDB.
Add these custom repositories to your composer.json
composer require silverstripe/dynamodb
If you wish to store sessions in DynamoDB, set the following environment variables in your
// the name of the DynamoDB table to store sessions in define('AWS_DYNAMODB_SESSION_TABLE', 'mysession'); // the region that the DynamoDB table will live in (in this example here it uses Sydney) define('AWS_REGION_NAME', 'ap-southeast-2');
Once these are in place, this module will configure DynamoDB and register that as the session handler.
Before you can actually use this, you need to create a table in which to store the sessions. This can be done through the AWS Console for Amazon DynamoDB, or using the SDK. When creating the table, you should set the primary key to
id of type
Sometimes you'll want to test that DynamoDB sessions work on your local development environment. You can make that
happen by defining
AWS_SECRET_KEY. Please don't define these constants in the environment file
in EC2 instances, as credentials are automatically handled by the IAM role inside of AWS.
// the AWS access key and secret. This is optional if you've configured an instance with an IAM role // http://docs.aws.amazon.com/aws-sdk-php/guide/latest/credentials.html#caching-iam-role-credentials define('AWS_ACCESS_KEY', '<access key here>'); define('AWS_SECRET_KEY', '<access secret here>');
Inactive sessions are garbage collected by
GarbageCollectSessionCronTask if silverstripe-crontask
is setup on your instance. The time when a session should be collected after inactivity can be changed by setting
For example, in your application's config YAML file, this sets a 20 minute session timeout:
Session: timeout: 1200
You can also set the DynamoDB garbage collection time independently of
Session::$timeout, but it's recommended you
make it at least the value of
Session::$timeout or greater.
For example, in your
_ss_environment.php file, set garbage collection after 1 hour of inactivity in sessions:
