ECS update monitor terraform module

This module can be used to wait for an update to an ECS service to apply.

Dependencies

This module depends on a python interpretter (2 or 3) and the boto3 module installed.

Input variables

• cluster - (required) The ECS cluster that the service is deployed to.
• service - (required) The name of the ECS service.
• taskdef - (required) The task definition ARN that the service is being updated to.

Example usage

If you are building a service, the chances are that you will be using a higher level module that includes this module. However, the following demonstrates how you might use this (e.g. in such a module):

resource "aws_ecs_task_definition" "taskdef" {
  family                = "my-service"
  container_definitions = "..."
}

resource "aws_ecs_service" "service" {
  name            = "my-service"
  task_definition = "${aws_ecs_task_definition.taskdef.arn}"
  cluster         = "my-cluster"
  desired_count   = "2"
}

module "ecs_update_monitor" {
  source = "github.com/mergermarket/tf_ecs_update_monitor"

  cluster = "my-cluster"
  service = "my-service"
  taskdef = "${aws_ecs_task_definition.taskdef.arn}"
}

Output

The module outputs information about the progress of the update to the user, exiting with a non-zero exit status should the deployment fail.
