RDS does not support creating a DB instance


When trying to create a docker i get the following errors. Is there any way to fix this?

An error occurred (InvalidParameterCombination) when calling the CreateDBInstance operation: RDS does not support creating a DB instance with the following combination: DBInstanceClass=db.t2.micro, Engine=postgres, EngineVersion=13.4, LicenseModel=postgresql-license. For supported combinations of instance class and database engine version, see the documentation.

Dear user,

The error message is correct. Amazon RDS does not support db.t2 family instances for PostgreSQL version 13 and higher: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.DBInstanceClass.html#Concepts.DBInstanceClass.Support

The only thing you can do to get your database instance created is to switch to a lower PostgreSQL version or change the instance type to one of the supported instance families, like t3 or t4g.

You see that error because, RDS PostgreSQL cannot be spun up on T2 instance class.

You can only create M6g, M5, T3, R6g, and R5 instance types. - https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_PostgreSQL.html

Change the instance class and try again. I am sure it would work.
