Building AMIs

This directory contains Packer files to build Amazon Machine Images (AMI) for the following components in the NGINX ACM demo:

1. ACM management
2. Devportal
3. API gateway

Prerequisites

• Packer
• NGINX Plus certificate and public key

Instructions

1. Create variables.pkrvars.hcl in this directory with the following variables

   Variable	Description
   version	Suffix to append to AMI names. If not provided, current timestamp is used instead.
   region	AWS region in which Packer builds and publishes AMIs
   nginx_repo_cert_path	Full path to certificate for accessing NGINX repo
   nginx_repo_key_path	Full path to key for accessing NGINX repo

   See variables.pkrvars.hcl.example for an example.

2. Build the images with the following commands

   packer init acm/ && \
         packer build -var-file=variables.pkrvars.hcl acm/
   packer init apigw/ && \
         packer build -var-file=variables.pkrvars.hcl apigw/
   packer init devportal/ && \
         packer build -var-file=variables.pkrvars.hcl devportal/

   Each command will output the AMI ID for the corresponding ACM component, as below

   ==> Builds finished. The artifacts of successful builds are:
   --> nms-apigw-1.0.0.amazon-ebs.ubuntu: AMIs were created:
   ap-southeast-2: ami-04f4ea46fafd660d3

3. Deploy the NGINX ACM environment with Terraform using the instructions here.
