README.md
Containerized Nginx on Container Optimized OS
This module manages a cloud-config
configuration that starts a containerized Nginx service on Container Optimized OS, using the hello demo image.
The resulting cloud-config
can be customized in a number of ways:
- a custom Nginx configuration can be set in
/etc/nginx/conf.d
using thenginx_config
variable - additional files (eg for hosts or zone files) can be passed in via the
files
variable - a completely custom
cloud-config
can be passed in via thecloud_config
variable, and additional template variables can be passed in viaconfig_variables
The default instance configuration inserts iptables rules to allow traffic on port 80.
Logging and monitoring are enabled via the Google Cloud Logging agent configured for the instance via the google-logging-enabled
metadata property, and the Node Problem Detector service started by default on boot.
The module renders the generated cloud config in the cloud_config
output, to be used in instances or instance templates via the user-data
metadata.
For convenience during development or for simple use cases, the module can optionally manage a single instance via the test_instance
variable. If the instance is not needed the instance*tf
files can be safely removed. Refer to the top-level README for more details on the included instance.
Examples
Default configuration
This example will create a cloud-config
that uses the module's defaults, creating a simple hello web server showing host name and request id.
module "cos-nginx" {
source = "./fabric/modules/cloud-config-container/nginx"
}
module "vm-nginx-tls" {
source = "./fabric/modules/compute-vm"
project_id = "my-project"
zone = "europe-west8-b"
name = "cos-nginx"
network_interfaces = [{
network = "default"
subnetwork = "gce"
}]
metadata = {
user-data = module.cos-nginx.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", "ssh"]
