Terraform module for enabling flow logs for vpc and subnets.
Tip
Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.
Watch demo of using Atmos with Terraform
Example of running
atmos to manage infrastructure from our Quick Start tutorial.
module "flow_logs" {
source = "git::https://github.com/cloudposse/terraform-aws-cloudwatch-flow-logs.git?ref=master"
vpc_id = "${var.vpc_id}"
namespace = "${var.namespace}"
stage = "${var.stage}"
}Important
In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.
