vim main.pkr.hcl
```sh
# ---------------------------------------------
# Variable declaration
# ---------------------------------------------
variable "access_key" {
default = ""
}
variable "secret_key" {
default = ""
}
variable "type" {
default = "t2.micro"
}
variable "region" {
default = "us-east-1"
}
# -----------------------------------------------
# Timestamp variable declaration on running time
# -----------------------------------------------
locals { timestamp = regex_replace(timestamp(), "[- TZ:]", "") }
#--------------------------------------------------
# Image Creation
#--------------------------------------------------
source "amazon-ebs" "webserver" {
source_ami_filter {
filters = {
virtualization-type = "hvm"
name = "amzn2-ami-hvm-2.0.*.1-x86_64-ebs"
root-device-type = "ebs"
}
owners = ["amazon"]
most_recent = true
}
access_key = "${var.access_key}"
ami_name = "packer-ami ${local.timestamp}"
instance_type = "${var.type}"
region = "${var.region}"
secret_key = "${var.secret_key}"
security_group_ids = [ "sg-0c8c8b94dc5c55c1d" ]
ssh_username = "ec2-user"
}
build {
sources = ["source.amazon-ebs.webserver"]
provisioner "ansible" {
playbook_file = "./play.yml"
}
post-processor "shell-local" {
inline = ["echo AMI Created"]
}
}
```

vim play.yml (Image provision using ansible)
```sh
