gcp-nginx-plus-with-nlb

This project is to create GCP infrastructure usign Terraform to deploy nginx plus as API Gateway and load balanced with NLB

Pre-requisite

1. Build the nginxplus image using packer ,follow the instructions
   here https://github.com/b-rajesh/diy-nplus-api-gwy-security-policies and get the image name to refer the same in this file https://github.com/b-rajesh/gcp-nginx-plus-with-nlb/blob/master/terraform.tfvars as nginx_plus_image_name_on_gcp
2. Build the following microservices image using packer, follow the instructions on each
   1. https://github.com/b-rajesh/hello-nginxplus
   2. https://github.com/b-rajesh/hello-f1
   3. https://github.com/b-rajesh/weather-api

3. Replace `terraform.tfvars` values with your `project_id` , `region` and other variables. Your  `project_id` &  `region`  must match the project you've initialized gcloud with.

Install appropriate GCP tools

First, install the Google Cloud CLI Install gcloud sdk - <Google Cloud SDK 284.0.0>

Initialize it...

$ gcloud init

gcloud Configure

$ gcloud auth login

Configure glcoud to work with your Terraform.

$ gcloud auth application-default login

Initialize Terraform workspace

Initalize your Terraform workspace, which will download the provider and initialize it with the values provided in the terraform.tfvars file.

$ terraform init

Initializing the backend...

Initializing provider plugins...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

Then, run plan terraform plan.

$ terraform plan
