## Packer demo on AWS with Ansible as Provisioner
This example shows how to use Packer to pre-bake AWS AMI with your desired configuration.
Ansible is used as provisioner to configure the image.
This setup uses *Amazon Linux* operating system.
Basic operations workflow:
- launch a temporary EC2 instance
- copy **scripts** and **ansible** folders to an instance
- install Ansible
- use Ansible to create a user and to install packages
- uninstall Ansible
- delete copied folders
## Installation
Requires [Packer](https://www.packer.io) and optionally AWS CLI for managing credentials.
```
git clone https://github.com/dmitrijsf/packer-ansible-aws-demo.git
cd packer-ansible-aws-demo
```
## Usage
**Copy your public key to ansible/files**
Note that public key name shoud be *id_rsa.pub* or Ansible *group_vars* will need to be adjusted.
```
❯ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/username/.ssh/id_rsa): keys/id_rsa
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in keys/id_rsa.
Your public key has been saved in keys/id_rsa.pub.
❯ cp keys/id_rsa.pub ansible/files
```
**Set desired AWS credentials**
In this example I am using [**aws-vault**](https://github.com/99designs/aws-vault) to work with desired profile.
Other options to set [AWS credentials for Packer](https://www.packer.io/docs/builders/amazon.html).
```
❯ aws-vault add home
Enter Access Key ID: your-aws-access-key-id
Enter Secret Access Key: your-aws-access-key+
Added credentials to profile "home" in vault
# launches subshell with desired AWS environment variables
❯ aws-vault --debug exec -- home
```
**Validate and Build with Packer**
```
❯ packer -v
1.1.3
❯ packer validate template_ami.json
Template validated successfully.
❯ packer build template_ami.json
amazon-ebs output will be in this color.
==> amazon-ebs: Prevalidating AMI Name: packer-ami 1517899734
amazon-ebs: Found Image ID: ami-d834aba1
-- cut --
==> Builds finished. The artifacts of successful builds are:
--> amazon-ebs: AMIs were created:
eu-west-1: ami-35472e4c
```
**Launch EC2 instance**
Now you can launch an EC2 instance from the new AMI.
Creating a key pair in AWS is not required as we have set it up with ansible.
```
❯ ssh -i keys/id_rsa [email protected]
-- cut --
Enter passphrase for key 'keys/id_rsa':
