Description

This repository is a selection of Terraform modules we used at Coveo. We now support the following modules :

rds_database_cluster

This module creates a RDS Cluster Resource, his RDS Cluster Resource Instance and a RDS DB subnet group ressource. It also store the database username and password into the parameter store by creating two SSM Parameter resource. You have to provide it with minimally a list of subnet_ids, the database master password and a custom_identifier. This module outputs the cluster endpoint which is the DNS address of the RDS instance, the master username, the master password and the port used by the database.

rds_database_instance

This module creates a RDS Instance Resource with a RDS DB subnet group ressource. It also store the database username and password into the parameter store by creating two SSM Parameter resource. You have to provide it with minimally a list of subnet_ids, the master password and a custom_identifier. This module outputs the connection endpoint, the master username, the master password and the port used by the database.

Usage

You can simply import the module you want to use in your terraform infrastructure directly from our github. We recommend using a tag to specify the version of the module you want to use. It will ensure your infrastructure won't stop working when a module is updated. The following example is how you would import the version 0.1 of the rds_database_cluster module in your terraform file.

source = "git::https://github.com/coveo/CoveoTerraformModules.git//rds_database_cluster?ref=v0.1"

Here is a more complete example using the optional parameters map :

data "null_data_source" "optional_parameters" {
  inputs = {
    backup_retention_period         = "YOUR RETENTION PERIOD"
    db_subnet_group_name            = "YOUR DB SUBNET GROUP NAME"
    db_cluster_parameter_group_name = "YOUR CLUSTER PARAMETER GROUP NAME"
    db_parameter_group_name         = "YOUR PARAMETER GROUP NAME"
    vpc_id                          = "YOUR VPC ID"
  }
}

module "rds_database_cluster" {
  source = "git::https://github.com/coveo/CoveoTerraformModules.git//rds_database_cluster?ref=v0.1"

  master_password        = "YOUR MASTER PASSWORD"
  subnet_ids             = ["YOUR SUBNET IDS"]
  custom_identifier      = ["A CUSTOM IDENTIFIER"]
  vpc_security_group_ids = ["A VPC SECURITY GROUP ID"]
  availability_zones     = ["AN AVAILABILITY ZONE", "ANOTHER AVAILABILITY ZONE"]
  optional_parameters    = "${data.null_data_source.optional_parameters.inputs}"

  db_tags = {
    "YOUR DB TAGS"
  }
}
