# AWS AMI Builder
Build Amazon Machine Images (AMIs) using Packer's `amazon-ebs` builder.
**Reference:** [Amazon EBS Builder](https://developer.hashicorp.com/packer/integrations/hashicorp/amazon/latest/components/builder/ebs)
> **Note:** Building AMIs incurs AWS costs (EC2 instances, EBS storage, data transfer). Builds typically take 10-30 minutes depending on provisioning complexity.
## Basic AMI Template
```hcl
packer {
required_plugins {
amazon = {
source = "github.com/hashicorp/amazon"
version = "~> 1.3"
}
}
}
variable "region" {
type = string
default = "us-west-2"
}
locals {
timestamp = regex_replace(timestamp(), "[- TZ:]", "")
}
source "amazon-ebs" "ubuntu" {
region = var.region
instance_type = "t3.micro"
source_ami_filter {
filters = {
name = "ubuntu/images/*ubuntu-jammy-22.04-amd64-server-*"
root-device-type = "ebs"
virtualization-type = "hvm"
}
most_recent = true
owners = ["099720109477"] # Canonical
}
ssh_username = "ubuntu"
ami_name = "my-app-${local.timestamp}"
tags = {
Name = "my-app"
BuildDate = local.timestamp
}
}
build {
sources = ["source.amazon-ebs.ubuntu"]
provisioner "shell" {
inline = [
"sudo apt-get update",
"sudo apt-get upgrade -y",
]
}
}
```
## Common Source AMI Filters
### Ubuntu 22.04 LTS
```hcl
source_ami_filter {
filters = {
name = "ubuntu/images/*ubuntu-jammy-22.04-amd64-server-*"
root-device-type = "ebs"
virtualization-type = "hvm"
}
most_recent = true
owners = ["099720109477"] # Canonical
}
```
### Amazon Linux 2023
```hcl
source_ami_filter {
filters = {
name = "al2023-ami-*-x86_64"
root-device-type = "ebs"
virtualization-type = "hvm"
}
most_recent = true
owners = ["amazon"]
}
```
## Multi-Region AMI
```hcl
source "amazon-ebs" "ubuntu" {
region = "us-west-2"
instance_type = "t3.micro"
source_ami_filter {
filters = {
name = "ubuntu/images/*ubuntu-jammy-22.04-amd64-server-*"
}
most_recent = true
owners = ["099720109477"]
}
ssh_username = "ubuntu"
ami_name = "my-app-${local.timestamp}"
# Copy to additional regions
ami_regions = ["us-east-1", "us-east-2", "eu-west-1"]
}
```
## Authentication
Packer uses AWS credential resolution:
1. Environment variables: `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`
2. AWS credentials file: `~/.aws/credentials`
3. IAM instance profile (when running on EC2)
```bash
export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_REGION="us-west-2"
packer build .
```
## Build Commands
```bash
# Initialize plugins
packer init .
# Validate template
packer validate .
# Build AMI
packer build .
# Build with variables
packer build -var "region=us-east-1" .
```
## Common Issues
**SSH Timeout**
- Ensure security group allows SSH (port 22)
- Verify subnet has internet access
**AMI Already Exists**
- AMI names must be unique
- Use timestamp in name: `my-app-${local.timestamp}`
**Volume Size Too Small**
- Check source AMI's volume size
- Set `launch_block_device_mappings.volume_size` accordingly

Review before install: Avoid automatic install
Install targets
Codex install prompt
Install the "aws-ami-builder" agent skill from https://github.com/hashicorp/agent-skills/tree/main/plugins/packer/skills/aws-ami-builder. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Build Amazon Machine Images (AMIs) with Packer using the amazon-ebs builder. Use when creating custom AMIs for EC2 instances. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"hashicorp-aws-ami-builder","task":"Install aws-ami-builder","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: plugins/packer/skills/aws-ami-builder/SKILL.md. Recorded revision: c2d65dfe492f74d360d35b859b88932222470bd8. Confirm the source matches these instructions.
