This lab will walk you through adding a provisioner to your Packer HCL Template. Provisioners use built-in and third-party software to install and configure the machine image after booting.
Duration: 30 minutes
- Task 1: Add a Packer provisioner to install all updates and the nginx service
- Task 2: Validate the Packer Template
- Task 3: Build a new Image using Packer
- Task 4: Install Web App
The Packer AWS builder supports the ability to create an AMI in multiple AWS regions. AMIs are specific to regions so this will ensure that the same image is available in all regions within a single cloud. We will also leverage Tags to indentify our image.
Validate that your aws-ubuntu.pkr.hcl file has the following Packer source block.
source "amazon-ebs" "ubuntu" {
ami_name = "packer-ubuntu-aws-{{timestamp}}"
instance_type = "t3.micro"
region = "us-west-2"
ami_regions = ["us-west-2", "us-east-1", "eu-central-1"]
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"]
}
ssh_username = "ubuntu"
tags = {
"Name" = "MyUbuntuImage"
"Environment" = "Production"
"OS_Version" = "Ubuntu 22.04"
"Release" = "Latest"
"Created-by" = "Packer"
}
}Add a provisioner to the builder block of your aws-ubuntu.pkr.hcl
build {
sources = [
"source.amazon-ebs.ubuntu"
]
provisioner "shell" {
inline = [
"echo Installing Updates",
"sudo apt-get update",
"sudo apt-get upgrade -y",
"sudo apt-get install -y nginx"
]
}
}Packer templates can be auto formatted and validated via the Packer command line.
Format and validate your configuration using the packer fmt and packer validate commands.
packer fmt aws-ubuntu.pkr.hcl
packer validate aws-ubuntu.pkr.hclThe packer build command is used to initiate the image build process for a given Packer template.
Run a packer build for the aws-ubuntu.pkr.hcl template.
packer build aws-ubuntu.pkr.hclPacker will print output similar to what is shown below. Note the connection to SSH and the provisioning of the updtes and services before the image is finalized.
amazon-ebs.ubuntu: output will be in this color.
