Terraform AWS® ECS Fargate InfluxDB EFS module

This module for Terraform (0.12+) helps to create the required resources to have an InfluxDB using EFS on ECS Fargate

This can be deactivated for testing purposes via use_efs = false. But keep in mind that the storage available to task in ECS-Fargate is limited!

Usage

resource "aws_service_discovery_private_dns_namespace" "example" {
  name = "example.local"
  vpc  = aws_vpc._.id
}

locals {
  common_tags = {
    source = "example"
    env    = terraform.workspace
  }

  admin_user = "admin"
  rw_user    = "rw_user"
  ro_user    = "ro_user"
}

resource "aws_security_group" "influxdb_access" {
  name        = "Example-${terraform.workspace}-influxdb_access"
  description = "Allow access to the Influxdb"
  vpc_id      = aws_vpc._.id

  ingress {
    from_port = 8086
    to_port   = 8086
    protocol  = "tcp"
    // Limit it
  }

  tags = merge(local.common_tags, {
    Name = "Example-${terraform.workspace}-influxdb_access"
  })
}

resource "aws_ecs_cluster" "_" {
  name = "Example-${terraform.workspace}"

  capacity_providers = ["FARGATE"]

  tags = local.common_tags
}

module "fargate-influxdb-efs" {
  source = "../fargate-influxdb-efs/"
  name   = "Example"
  tags   = local.common_tags

  aws_service_discovery_private_dns_namespace = aws_service_discovery_private_dns_namespace.example


  aws_ecs_cluster = aws_ecs_cluster._
  cpu             = 512
  memory          = 2048

  execution_role = aws_iam_role.influxdb_execution
  task_role      = aws_iam_role.influxdb
  
  admin_user                                 = local.admin_user
  aws_secretsmanager_secret-admin_password   = aws_secretsmanager_secret_version.influxdb_admin-password
  rw_user                                    = local.rw_user
  aws_secretsmanager_secret-rw_user_password = aws_secretsmanager_secret_version.influxdb_rw_user-password
  ro_user                                    = local.ro_user
  aws_secretsmanager_secret-ro_user_password = aws_secretsmanager_secret_version.influxdb_ro_user-password

  aws_vpc            = aws_vpc._
  aws_subnets        = aws_subnet._
  aws_security_group = aws_security_group.influxdb_access
}
