terraform-aws-ecs-scheduled-task

Terraform module which creates ECS Scheduled Task resources on AWS.

Description

Provision ECS Task Definitions and CloudWatch Events.

This module provides recommended settings:

• Fargate launch type
• Disable assign public ip address

Usage

Minimal

module "ecs_scheduled_task" {
  source                = "git::https://github.com/tmknom/terraform-aws-ecs-scheduled-task.git?ref=tags/2.0.0"
