apt-transport-https missing

[src386]

Debian 9 Stretch, ansible version:

root@debian9:~# ansible --version
ansible 2.2.1.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides

Playbook:

- hosts: localhost

  roles:
    - debops.docker

  vars:
    - docker__upstream: 'True'

(I use the docker__upstream var as a workaround for #51 )

Play :

root@debian9:~# ansible-playbook playbook.yml 
 [WARNING]: provided hosts list is empty, only localhost is available

Workaround:

apt-get install apt-transport-https

Currently this is not fixed, the role expects at least the debops.apt configuration to be appled on the host, that role installs apt-transport-https package. I guess a task that ensures that this package is present should be added here, epseically that upstream repository works with HTTPS. Still, this should be fixed in the DebOps monorepo where the main development is currently done.

Thanks for this and for #51
What if I 'backport' those fixes and make a pull request ?
DebOps monorepo seems to big for my needs, I like standalone ansible roles.

@src386 Since standalone DebOps roles from the monorepo won't be available for some time, sure - if you want, you can make a backport to debops/ansible-docker and a PR; if it passes it will be merged.
