| # Terraform Database Example | ||
|
|
||
| This creates an example postgres instance using docker. | ||
|
|
||
| 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. | ||
