9	## Basic AMI Template
10
11	```hcl
12	packer {
13	required_plugins {
14	amazon = {
15	source = "github.com/hashicorp/amazon"
16	version = "~> 1.3"
17	}
18	}
19	}
20
21	variable "region" {
22	type = string
23	default = "us-west-2"
24	}
25
26	locals {
27	timestamp = regex_replace(timestamp(), "[- TZ:]", "")
28	}
29
30	source "amazon-ebs" "ubuntu" {
31	region = var.region
32	instance_type = "t3.micro"
33
34	source_ami_filter {
35	filters = {
36	name = "ubuntu/images/ubuntu-jammy-22.04-amd64-server-"
37	root-device-type = "ebs"
38	virtualization-type = "hvm"
39	}
40	most_recent = true
41	owners = ["099720109477"] # Canonical
42	}
43
44	ssh_username = "ubuntu"
45	ami_name = "my-app-${local.timestamp}"
46
47	tags = {
48	Name = "my-app"
49	BuildDate = local.timestamp
50	}
51	}
52
53	build {
54	sources = ["source.amazon-ebs.ubuntu"]
55
56	provisioner "shell" {
57	inline = [
58	"sudo apt-get update",
59	"sudo apt-get upgrade -y",
60	]
61	}
62	}
63	```
64
65	## Common Source AMI Filters
66
67	### Ubuntu 22.04 LTS
68	```hcl
69	source_ami_filter {
70	filters = {
71	name = "ubuntu/images/ubuntu-jammy-22.04-amd64-server-"
72	root-device-type = "ebs"
73	virtualization-type = "hvm"
74	}
75	most_recent = true
76	owners = ["099720109477"] # Canonical
77	}
78	```
79
80	### Amazon Linux 2023
81	```hcl
82	source_ami_filter {
83	filters = {
84	name = "al2023-ami-*-x86_64"
85	root-device-type = "ebs"
86	virtualization-type = "hvm"
87	}
88	most_recent = true
89	owners = ["amazon"]
90	}
91	```
92
93	## Multi-Region AMI
94
95	```hcl
96	source "amazon-ebs" "ubuntu" {
97	region = "us-west-2"
98	instance_type = "t3.micro"
99
100	source_ami_filter {
101	filters = {
102	name = "ubuntu/images/ubuntu-jammy-22.04-amd64-server-"
103	}
104	most_recent = true
105	owners = ["099720109477"]
106	}
107
108	ssh_username = "ubuntu"
109	ami_name = "my-app-${local.timestamp}"
110
111	# Copy to additional regions
112	ami_regions = ["us-east-1", "us-east-2", "eu-west-1"]
113	}
114	```
115
116	## Authentication
117
118	Packer uses AWS credential resolution:
119
120	1. Environment variables: `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`
121	2. AWS credentials file: `~/.aws/credentials`
122	3. IAM instance profile (when running on EC2)
123
124	```bash
125	export AWS_ACCESS_KEY_ID="your-access-key"
126	export AWS_SECRET_ACCESS_KEY="your-secret-key"
127	export AWS_REGION="us-west-2"
128
129	packer build .
130	```
131
132	## Build Commands
133
134	```bash
135	# Initialize plugins
136	packer init .
137
138	# Validate template
139	packer validate .
140
141	# Build AMI
142	packer build .
143
144	# Build with variables
145	packer build -var "region=us-east-1" .
146	```
147
148	## Common Issues
149
150	SSH Timeout
151	- Ensure security group allows SSH (port 22)
152	- Verify subnet has internet access
153
154	AMI Already Exists
155	- AMI names must be unique
156	- Use timestamp in name: `my-app-${local.timestamp}`
157
158	Volume Size Too Small
159	- Check source AMI's volume size
160	- Set `launch_block_device_mappings.volume_size` accordingly
