This project uses a tool called batect to run the application. It uses a docker container to create a portable build environment. In order to run the sample Packer template simply ensure docker is running on your machine and run either of the following commands:
Packer Validate:
./batect validate
Packer Build:
./batect build
You can also choose to install Packer manually or via brew. Full instructions can be found on the Packer home page.
Additionally you may use the offical DockerHub image
