Kitchen Login Fails w. Unprotected Private Key File

[darkn3rd]

Running kitchen create and kitchen login fails as permissions are too open.

STEPS

$ export KITCHEN_YAML=kitchen.docker.yml
$ kitchen create
$ ls -la .kitchen/docker_id_rsa
-rw-r--r--  1 jmenchaca  staff  1679 Oct 28 23:40 .kitchen/docker_id_rsa
$ kitchen login

The config is the following:

---
driver:
  name: docker

provisioner:
  name: ansible_playbook
  hosts: all
  require_ansible_repo: true
  require_ansible_omnibus: false
  ansible_verbose: true
  ansible_verbosity: <%= ENV['ANSIBLE_VERBOSITY'] || 1 %>
  ansible_diff: true
  roles_path: ../../roles
  require_chef_for_busser: true

verifier:
  name: inspec

platforms:
  - name: ubuntu-16.04
    transport:
      max_ssh_sessions: 6

suites:
  - name: default
    verifier:
      inspec_tests:
        - test/integration/default
      attributes:
        service_type: sysv

EXPECTED RESULTS

Login with similar behavior as if I was using vagrant.
