Packer on Windows
Overview
HashiCorp Packer is an open-source tool that builds identical machine images for multiple platforms from a single source configuration. It automates the creation of AMIs, Docker images and other machine image formats.
This SecureAnyCloud AMI on AWS Marketplace gives you a Windows Server instance with Packer already installed, so you can connect over Remote Desktop and start building images straight away.
What you get:
- HashiCorp Packer (latest version) preinstalled in the system PATH
- A Command Prompt desktop shortcut for quick CLI access
- Windows Server with Remote Desktop access
- 24/7 SecureAnyCloud support with a guaranteed 24-hour response SLA
Prerequisites
Before you launch the AMI, make sure you have:
- An active AWS account
- An active subscription to the Packer on Windows listing on AWS Marketplace
- An EC2 key pair for password decryption
- A Remote Desktop client application
Recommended instance type: t3.medium (2 vCPU, 4 GB RAM) or larger. The minimum requirements are 1 vCPU, 1 GB RAM and 30 GB of disk space.
Launch the AMI
- Open AWS Marketplace and search for "Packer Windows SecureAnyCloud".
- Select Continue to Subscribe, accept the terms, then select Continue to Configuration.
- Choose your Region and Software Version.
- Select Continue to Launch.
- Choose Launch through EC2 for full control over instance configuration.
- Select your instance type.
t3.mediumis recommended. - Configure storage with at least 30 GB of gp3.
- Configure your Security Group with the inbound rule below.
Allow inbound TCP on port 3389 from your IP address only. This rule provides Remote Desktop (RDP) access.
- Select your EC2 key pair and launch the instance.
Retrieve the Windows password
Wait for the EC2 instance to pass its 2/2 status checks. The Windows password can take up to 15 minutes after launch to become available.
- Open the AWS Console and go to EC2 > Instances.
- Select your instance.
- Choose Actions > Security > Get Windows password.
- Select Browse and upload your EC2 key pair
.pemfile. - Select Decrypt password.
- Note the Username (
Administrator) and the decrypted Password.
Connect over Remote Desktop
Open your Remote Desktop client.
On Windows: press Win + R, type mstsc and press Enter. Enter the public IP address of your instance, then select Connect.
On macOS: open Microsoft Remote Desktop and select Add PC. Enter the public IP address, then double-click the connection to connect.
When prompted, enter Username: Administrator and Password: the decrypted value from Step 2.
If a certificate warning appears, select Continue to proceed.
Verify the Packer installation
Once connected, open Command Prompt from the desktop shortcut and confirm that Packer is installed.
packer -helpThe command prints the usage text and the list of available commands:
Usage: packer [--version] [--help] <command> [<args>] Available commands are: build build image(s) from template console creates a console for testing variable interpolation fix fixes templates from old versions of packer fmt rewrites HCL2 config files to canonical format hcl2_upgrade transform a JSON template into an HCL2 configuration init install missing plugins or upgrade plugins inspect see components of a template plugins interact with Packer plugins and catalog validate check that a template is valid version prints the Packer versionThen check the installed version:
packer versionBuild your first AMI
Create an example Packer template.
Create a project directory:
cmd mkdir C:\Users\Administrator\Documents\packer-project cd C:\Users\Administrator\Documents\packer-project
Create a template file named example.pkr.hcl:
cmd notepad example.pkr.hcl
Enter a basic Amazon EBS template:
```hcl packer { required_plugins { amazon = { version = ">= 1.0.0" source = "github.com/hashicorp/amazon" } } }
source "amazon-ebs" "example" { ami_name = "packer-example-{{timestamp}}" instance_type = "t3.micro" region = "us-east-1" source_ami_filter { filters = { name = "amzn2-ami-hvm-*-x86_64-gp2" root-device-type = "ebs" virtualization-type = "hvm" } most_recent = true owners = ["amazon"] } ssh_username = "ec2-user" }
build { sources = ["source.amazon-ebs.example"] provisioner "shell" { inline = ["echo 'Hello from Packer!'"] } } ```
Initialize the plugins:
cmd packer init example.pkr.hcl
Validate the template:
cmd packer validate example.pkr.hcl
Build the image. This requires AWS credentials to be configured (see the next section):
cmd packer build example.pkr.hcl
Configuring AWS Credentials
To build AWS AMIs, give Packer access to your AWS credentials using one of these methods.
Method 1: Environment variables
set AWS_ACCESS_KEY_ID=your-access-key set AWS_SECRET_ACCESS_KEY=your-secret-key set AWS_DEFAULT_REGION=us-east-1Method 2: IAM instance role (recommended)
Attach an IAM role with the required EC2 permissions to the instance. This avoids storing credentials on the server.
Method 3: AWS CLI configuration
aws configureServer Components
- Packer: latest version
Filesystem Layout
The system drive C:\ holds Windows and the Packer installation.
Key directories:
- C:\Users\Administrator: user home directory
- C:\Users\Administrator\Documents: default working directory for templates
- C:\Users\Administrator\AppData\Roaming\packer.d: Packer plugins directory
Troubleshooting
Packer command not found
- Open Command Prompt and run
packer version. - Check that Packer is in the system PATH with
echo %PATH%. - Search for the Packer binary with
where packer.
Build fails with an AWS authentication error
- Check that your AWS credentials are configured correctly.
- Check that your IAM permissions include EC2, S3 and AMI-related actions.
- Check that the region is set correctly.
- Run
aws sts get-caller-identityto verify your credentials.
Build times out
- Increase the
ssh_timeoutorcommunicatortimeout in your template. - Check that the source AMI exists in the specified region.
- Check that your security group allows SSH or WinRM access during the build.
Cannot connect over RDP
- Check that the instance has passed its 2/2 status checks.
- Check that your security group allows port 3389 from your IP.
- Wait up to 15 minutes for the Windows password to become available.
Security Recommendations
- Change the Administrator password after your first login.
- Use IAM roles instead of access keys for AWS authentication.
- Restrict RDP access. Allow port 3389 only from your own IP address.
- Keep credentials out of templates. Use environment variables or IAM roles instead.
- Enable Windows Update. Keep the operating system patched with the latest security updates.
- Keep Packer updated. Check regularly for new versions and security fixes.
- Validate templates before building. Always run
packer validatebeforepacker build.
