Description

I want to be able to edit the packer user's groups, then tell packer to refresh the ssh connection so that I don't have to do any hacky business to get my permissions -- I want to be able to tell packer to logout, and login.

Use Case(s)

I am building an EC2 image with a docker image on it. I have to run the docker commands as sudo.

Potential configuration

  provisioner "shell" {
    inline = [
      "sudo usermod -a -G docker ec2-user"
    ]
  }
  # 2nd shell provisioner, that can be configured to refresh the connection
  provisioner "shell" {
    new_connection = true
    inline = [
      "docker run hello-world"
    ]
  }

Potential References

This was brought up in an old thread of google groups.

My workaround:

provisioner "shell" {
  script = ...
  execute_command = "sudo su -l docker -c '{{ .Vars }} {{ .Path }}'"
}
