What Is Ansible Packer & How Does It Work?

Are you still manually building servers upon deployment? It will consume your time and produce irregular results. This is why Ansible Packer is so powerful. You can build ready-to-use images instead of configuring the machine.

Using Packer and Ansible, you create a clean base image and then add configuration during the build. So servers are configured when they boot – no post-boot configuration. No repetition.

In reality, in DevOps, time flows much faster. With Ansible and Packer, teams can cut down on deployment times, eliminate configuration drift, and synchronize environments both pre- and in-production.

The Packer Ansible provisioner is the important one. It executes the Ansible playbook during the building of the image.

It makes sure each image has exactly the same configuration, package, and setup. In this article, you will learn how Ansible Packer works, how to use the Packer Ansible provisioner with Packer, and how to overcome it in a real automation. with real examples, outputs workflows.

What is Ansible Packer?

Ansible Packer is the integration of Packer with Ansible to build and configure machine images automatically. You can create pre-configured images by running Ansible playbooks during the image build process.

Why Use Packer And Ansible Together?

When you use Packer and Ansible, it solves a major problem, i.e., inconsistent environments. Without integration, you will need manual configuration after deployment, slow server setup, and a high risk of errors. With Ansible Packer, you have pre-configured images, faster deployments, and consistent infrastructure.

Ansible And Packer Workflow

What Is Packer Ansible Provisioner?

It is used to execute Ansible playbooks during the image build process. Here are the key benefits:

• Reuse existing playbooks
• Automate configuration
• Ensure consistency

How to Use Packer Ansible Provisioner?

Let’s learn the use of Packer Ansible Provisioner with the help of an example. Here are the steps:

Step 1: Create Ansible Playbook

- hosts: all
  become: yes
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present

- hosts: all
  become: yes
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present

Step 2: Create Packer Template

{
  "builders": [
    {
      "type": "amazon-ebs",
      "region": "us-east-1",
      "source_ami": "ami-123456",
      "instance_type": "t2.micro",
      "ssh_username": "ubuntu",
      "ami_name": "nginx-image"
    }
  ],
  "provisioners": [
    {
      "type": "ansible",
      "playbook_file": "playbook.yml"
    }
  ]
}

{
  "builders": [
    {
      "type": "amazon-ebs",
      "region": "us-east-1",
      "source_ami": "ami-123456",
      "instance_type": "t2.micro",
      "ssh_username": "ubuntu",
      "ami_name": "nginx-image"
    }
  ],
  "provisioners": [
    {
      "type": "ansible",
      "playbook_file": "playbook.yml"
    }
  ]
}

Step 3: Run build

packer build template.json

packer build template.json

Output

Build finished. Image created successfully.

Build finished. Image created successfully.

What Happens During Ansible Packer Execution?

• Packer creates temporary instance
• Ansible connects via SSH
• Playbook runs
• Image is saved

This ensures identical configuration every time.

When to Use & Avoid Ansible Packer?

You should use it when:

• You need repeatable images
• You deploy frequently
• You want a faster startup
