GitHub

Create a classic personal access token in GitHub by navigating to Settings → Developer Settings → Personal Access Tokens → Tokens (classic) → Generate New Token. Now, copy the token somewhere securely and export it to shell as follows:

export PKR_VAR_github_pat=<github-pat>

AWS

To create an AMI (Amazon Machine Image) on AWS, export the following variables to the shell as follows:

export AWS_ACCESS_KEY_ID=<access-key-id>
export AWS_SECRET_ACCESS_KEY=<secret-access-key>
export AWS_REGION=<aws-region>

Azure

Azure, as usual is bit tedious to set-up when compared to AWS. Firstly, make sure Azure CLI is installed on your machine. Now, get the subscription ID as follows:

az account show --query "{ subscription_id: id }"

Get the client ID, client secret and tenant ID with the following command. Make sure to replace the <subscription-id> with your subscription ID.

az ad sp create-for-rbac --role Contributor --scopes /subscriptions/<subscription-id> --query "{ client_id: appId, client_secret: password, tenant_id: tenant }"

Now, create a resource group with the following command. Feel free to choose a resource name and location as per your likings.

az group create -n wireguard-ubuntu -l centralindia

Export the following environment variables with the secrets obtained from preceeding steps. The commands are listed below:

export PKR_VAR_azure_client_id=<client-id>
export PKR_VAR_azure_client_secret=<client-secret>
export PKR_VAR_azure_subscription_id=<subscription-id>
export PKR_VAR_azure_tenant_id=<tenant-id>

Building Image with Packer

Note: The HCL scripts builds images for both AWS and Azure. Make sure to comment-out either one if you're not willing to deploy.

Make sure to modify the ./scripts/user-data.sh according to your needs before proceeding. The final steps are to initialize the integration modules, format, validate and build the images.

packer init ./
packer validate ./ && packer fmt ./
packer build ./
