Superblocks Terraform Module - Google

+ +This document contains configuration and deployment details for deploying the Superblocks agent to Google Cloud. + +## Deploy with Terraform + +### Install Terraform + +To install Terraform on MacOS +``` +brew tap hashicorp/tap +brew install hashicorp/tap/terraform +``` + +Terraform officially supports `MacOS|Windows|Linux|FreeBSD|OpenBSD|Solaris` +Check out this https://developer.hashicorp.com/terraform/downloads for more details + +### Deploy Superblocks On-Premise-Agent + +#### Create your Terraform file +To get started, you'll need a `superblocks_agent_key`.

You can update the ingress rules to "Only allow internal traffic" by adding the following to the Terraform module +​ +``` +internal = true +``` + +#### Custom Domain Mapping +By default, this module will try to configure a **custom domain** for your Cloud Run service, for example `subdomain.example.com`. This configures both the [Cloud Run Domain Mapping](https://cloud.google.com/run/docs/mapping-custom-domains#map) and a CNAME DNS record for your `domain`. +​ +For this to work successfully, you must verify ownership of your `domain` with Google, and have a Cloud DNS Zone configured for the domain. To verify domain ownership, use the Google CLI command `gcloud domains verify ${domain}`. Find the Cloud DNS Zone Name for your domain by running `gcloud dns managed-zones list --filter "dns_name ~ ${domain}`. +​ +If you don't use Google Cloud DNS, or want to manually configure the Domain Mapping, just disable DNS creation by adding the following to the Terraform module +​ +``` +create_dns = false +``` + +If you decide to manually set up a custom domain for your Cloud Run service, follow Google's instructions for [Mapping customer domains](https://cloud.google.com/run/docs/mapping-custom-domains#run) + +#### Instance Sized +Configure the CPU & memory limits for your Cloud Run instances by adding the following variables to your Terraform module +``` +container_requests_cpu = "512m" +container_requests_memory = "1024Mi" +container_limits_cpu = "1.0" +container_limits_memory = "2048Mi" + +``` + +#### Scaling +Google will automatically scale your Cloud Run instances based on traffic.
