AWS Administration Cookbook

How to do it...

1. Create a new Packer template file, and start by defining an amazon-ebs builder in the builders section:

      "builders": [         {           "type": "amazon-ebs",           "instance_type": "t2.micro",           "region": "us-east-1",           "source_ami": "ami-9be6f38c",           "ssh_username": "ec2-user",           "ami_name": "aws-linux-apache {{timestamp}}"         }       ],

The entire template file must be a valid JSON object. Remember to enclose the sections in curly braces: { ... }.

2. Create a provisioners section, and include the following snippet to install and activate Apache:

      "provisioners": [         {           "type": "shell",           "inline": [             "sudo yum install -y httpd",             "sudo chkconfig httpd on"           ]         }       ]

3. Save the file with a specific name, such as 04-creating-machine-images.json.
