We have druid instance running on AWS with metadata store as PostgreSQL.
We received this email from AWS. Can someone share there experience updating this certificate for Druid (postgress as metadata storeage) ?
We previously sent a communication in early October to update your RDS SSL/TLS certificates by October 31, 2019. We have extended the dates and now request that you act before February 5, 2020 to avoid interruption of your applications that use Secure Sockets Layer (SSL) or Transport Layer Security (TLS) to connect to your RDS and Aurora database instances. Note that this new date is only 4 weeks before the actual Certificate Authority (CA) expiration on March 5, 2020. Because our own deployments, testing, and scanning to validate all RDS instances are ready for the expiry must take place during the final 4 weeks, the February 5th date cannot be further extended.
You are receiving this message because you have an Amazon RDS database instance(s) that requires action in the US-XXX-1 Region, listed in the ‘Affected resources’ tab in your Personal Health Dashboard.
To protect your communications with RDS database instances, a CA generates time-bound certificates that are checked by your client applications that connect via SSL/TLS to authenticate RDS databases before exchanging information. AWS renews the CA and creates new root certificates every five years to ensure RDS customer connections are properly protected for years to come.
The current CA expires on March 5, 2020, requiring updates to client applications and database instances that have certificates referencing the current CA. Client applications must add new CA certificates (root and intermediate where necessary) to their trust stores, and RDS database instances must separately use new server certificates before this hard expiration date. However, we strongly recommend you complete these changes before February 5, 2020. After February 5, 2020, we will begin scheduling certificate rotations for your RDS database instances prior to the March 5, 2020 deadline. The automatic update(s) will be scheduled within your maintenance window.
Additionally, any new RDS database instances created after January 14, 2020 (previously November 1, 2019) will default to using the new certificates. If your client applications have not been updated to add the new certificates to their trust stores, these applications will fail to connect to any new instances created after this date. If you wish to temporarily modify new instances to use the old certificates, you can do so using the AWS console, the RDS API, and the AWS CLI. Any instances created prior to January 14, 2020 will have the old certificates until you update them to the rds-ca-2019 version.
If your applications connect to RDS database instances using the SSL/TLS protocol, please follow the detailed instructions in the links below. Based on your feedback, we have provided, per database engine, further instructions on 1.) how to determine whether your client applications are connecting to your RDS databases via SSL/TLS and 2.) how to update your client application trust stores to include the new CA certificates.
If your applications do not use SSL/TLS to connect, there are no required actions that you need to take. However, using SSL/TLS is a security best practice so we recommend all customers perform this upgrade so that your applications can start using SSL seamlessly. Before March 5, 2020, RDS will schedule and perform pending maintenance actions which you can view in the RDS console to ensure you have valid certificates after the current certificates expire. The automatic update(s) will be scheduled within your maintenance window.
For RDS: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.SSL-certificate-rotation.html
For Aurora: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/UsingWithRDS.SSL-certificate-rotation.html
We encourage you to test these steps in a development or staging environment before implementing them in your production environments. If not completed, your applications using SSL/TLS will fail to connect to your existing database instances as soon as RDS rotates your certificates on the database side prior to March 5, 2020.
