| # MySQL Example | ||
|
|
||
| Configuration in this directory creates a MySQL Aurora cluster with parameter group. | ||
|
|
||
| ## Usage | ||
|
|
||
| To run this example you need to execute: | ||
|
|
||
| ```bash | ||
| $ terraform init | ||
| $ terraform plan | ||
| $ terraform apply | ||
| ``` | ||
|
|
||
| Note that this example may create resources which cost money. Run `terraform destroy` when you don't need these resources. | ||
