# Containerized Nginx with self-signed TLS on Container Optimized OS

This module manages a `cloud-config` configuration that starts a containerized Nginx with a self-signed TLS cert on Container Optimized OS. This can be useful if you need quickly a VM or instance group answering HTTPS for prototyping.

The generated cloud config is rendered in the `cloud_config` output, and is meant to be used in instances or instance templates via the `user-data` metadata.

## Example

```hcl
module "cos-nginx-tls" {
  source = "./fabric/modules/cloud-config-container/nginx-tls"
}

module "vm-nginx-tls" {
  source     = "./fabric/modules/compute-vm"
  project_id = "my-project"
  zone       = "europe-west8-b"
  name       = "cos-nginx-tls"
  network_interfaces = [{
    network    = "default"
    subnetwork = "gce"
  }]
  metadata = {
    user-data              = module.cos-nginx-tls.cloud_config
    google-logging-enabled = true
  }
  boot_disk = {
    initialize_params = {
      image = "projects/cos-cloud/global/images/family/cos-stable"
      type  = "pd-ssd"
      size  = 10
    }
  }
  tags = ["http-server", "https-server", "ssh"]
}
