Module Features

This module implements the following terraform resources:

google_sql_database_instance
google_sql_database
google_sql_ssl_cert
google_sql_user

Getting Started

Most basic usage just setting required arguments:

module "terraform-google-cloud-sql" {
  source = "github.com/mineiros-io/terraform-google-cloud-sql.git?ref=v0.1.0"

  tier             = "db-f1-micro"
  database_version = "MYSQL_5_6"
}

Module Argument Reference

See variables.tf and examples/ for details and use-cases.

Module Configuration

module_enabled: (Optional bool)

Specifies whether resources in the module will be created.

Default is true.
module_depends_on: (Optional list(dependency))

Module Versioning

This Module follows the principles of Semantic Versioning (SemVer).

Given a version number MAJOR.MINOR.PATCH, we increment the:

MAJOR version when we make incompatible changes,
MINOR version when we add functionality in a backwards compatible manner, and
PATCH version when we make backwards compatible bug fixes.

Backwards compatibility in `0.0.z` and `0.y.z` version

Backwards compatibility in versions 0.0.z is not guaranteed when z is increased. (Initial development)
Backwards compatibility in versions 0.y.z is not guaranteed when y is increased. (Pre-release)
