AWS Aurora RDS PostgreSql 通过云形成脚本为现有集群创建全局数据库

Question

We already have a cluster and instance of Aurora PostgreSql in abc region. Now as part of disaster recovery strategy, we are trying to create a read replica in a xyz region.

I was able to create it manually by clicking on "Add Region" in AWS web console. As explained here .

As part of it, following as been created. 1. A global database to the existing cluster 2. Secondary region cluster 3. Secondary region instance.

Everything is fine. Now I have to implement this through cloud formation script.

My first question is, can we do this through Cloud formation script without losing data if primary cluster and instance already created?

If possible, please share aws doc for cloud formation scripts.

Answer 1

Please see the other post on this subject: CloudFormation templates for Global Aurora Database

The API that is required for setting up the GlobalCluster is AWS::RDS::GlobalCluster and this is currently not listed in CloudFormation documentation .

I was able to do the same using Terraform and that is documented for PostgreSQL here: Getting Aurora PostgreSQL Global Database setup using Terraform
