Add expect_disconnect

[gadelkareem]

Description

Which provisioning using Ansible, I often need to reboot the VM but there is no such option as expect_disconnect

Potential configuration

provisioner "ansible-local" {
    max_retries             = 5
    playbook_dir            = "ansible"
    playbook_file           = "reboot-playbook.yml"
    timeout                 = "10m0s"
    clean_staging_directory = true
  }

+1 to this, I am trying to set up a playbook that calls the builtin reboot module, but any time I use that it fails with ==>: dial tcp 172.16.161.128:22: connect: connection refused for example and never reconnects.

@gadelkareem Do you have a workaround?

[gadelkareem]

@BytesGuy yes workaround here https://github.com/gadelkareem/ubuntu20-vagrantbox/blob/main/packer/vagrant/ubuntu.pkr.hcl#L97

  provisioner "ansible-local" {
    max_retries             = 5
    playbook_dir            = "packer/vagrant/ansible"
#    galaxy_file              = "packer/vagrant/ansible/requirements.yml"
    playbook_file            = "packer/vagrant/ansible/vagrant-playbook.yml"
    timeout                 = "10m0s"
    inventory_groups        = ["base"]
    clean_staging_directory = true
  }

  provisioner "shell" {
    expect_disconnect = true
    inline            = ["sudo reboot now"]
    pause_before      = "10s"
    timeout           = "10m0s"
  }

@gadelkareem Ah ok so basically we will have to break out of the playbook and run the reboot via Packer directly. That's going to be a bit messy to do in the middle where I need to do it but it will have to do for now 😂

Hopefully some kind of expect disconnect feature can be added to the plugin soon!
