# Terraform Database Example
2+
3+
This creates an example postgres instance using docker.
4+
5+
Check out [test/terraform_database_example_test.go](/test/terraform_database_example_test.go) to see how you can write automated tests for database. In order to make go test code work, you need to provide host, port, username, password and database name of a existing database, which you have already created on cloud platform or using docker before testing. Only Microsoft SQL Server, PostgreSQL and MySQL are supported.
