This is a custom Github Action to build Packer Images on Cloud. This only has support for GCP as of now but we'll add support for AWS and Azure as well.
This action currently supports 3 input variables.
- main_file(Required): This is the configuration file which contains your Packer configuration. Only has support for the JSON types as of now.
- variable_file(Optional): This is the file which contains all the variables needed by your main configuration file. Only has support for the JSON type as of now.
- working_directory(Optional): This is the directory which contains your packer configuration code relative to the root of your repository. Defaults to root directory(.)in the repository.
- arguments(Optional): These are the Command Line Arguments with the packer build command. Refer the documentation
For this Github action to work, you need to have first checked out the repository on your Github Actions runner and configured authentication with GCP.
To configure authentication with GCP, you can either use Workload Identity Federation(recommended) or use a long-lived Service Account Key to impersonate a GCP Service Account.
Please refer to Google Auth repository.
