Change options

Customize some data from the Amazon environment by editing the centreon-local.json file in the amazon-ebs build block, as in the example below

    {
      "type" : "amazon-ebs",
      "access_key": "{{user `aws_access_key`}}",
      "secret_key": "{{user `aws_secret_key`}}",
      "profile" : "default",
      "region" : "us-east-2",
      "instance_type" : "t2.micro",
      "source_ami" : "ami-e0eac385",
      "ssh_username" : "centos",
      "ami_name" : "Centreon 20.04 Build 0.0.1",
      "ami_description" : "Centreon 20.04 OSS",
      "run_tags" : {
          "Name" : "packer-builder-centreon",
          "Tool" : "Packer",
          "Author" : "Luiz Costa <me@luizgustavo.pro.br>"
      }
    }

To obtain a list of Centos images (for use in source_ami option) available for the region you want to use in creating your image, using Amazon's cli, use the following command (change region for you choice)

aws --region us-east-1 ec2 describe-images --owners aws-marketplace --filters Name=product-code,Values=aw0evgkw8e5c1q413zgy5pjce

always give preference to the most current images

For build image

packer build -only="amazon-ebs" \
    -var 'aws_access_key=XXXXXXXXXXXXXXX' \
    -var 'aws_secret_key=XXXXXXXXXXXXXXX' \
    -var-file vars/centreon-2004.json \
    centreon-local.json

Change variables aws_access_key and aws_secret_key for you values

For make a new instancie of EC2 with image builded

aws ec2 run-instances --image-id <ami image id> \
    --count 1 --instance-type t2.micro \
    --key-name <you_sshkey> \
