# Terraform Docker Packer

This Terraform module serves as an abstraction to builds machine images from Packer configurations through Docker.  
A pre-existing Docker image with Packer installed is required.  
  
You may run the example to build a RaspiOS ARM64 image:
```
pushd examples/raspios
    terraform init
    terraform apply
    docker logs -f $(docker ps -q -f name=packer-builder-arm)
popd
```

## Build Progress

The build runs in the background and outpout the image to the local directory.  
To see the build progress, you need to show the Docker logs like this:
```
docker logs -f $(docker ps -q -f name=packer-builder-arm)
```
