Description

We use Jenkins to do packer builds in AWS, and the progress bars for copying files take an exorbitant amount of space in the logs. We would like to disable the progress bars for file copies entirely.

Use Case(s)

Give this template:

"provisioners": [
  {
    "type": "file",
    "source": "provisioners/files/SetEnvironmentVariables.ps1",
    "destination": "C:/LM-Build/"
  }
}

We get this output:

This is automatic as of v1.6.1 if you set the --machine-readable flag, or as of v 1.6.3 if you run Packer as a background process.

That said, adding an actual flag should be feasible as well.
