Alex Willmer a8e8cf91cb tests: Rebuild Docker containers
A few changes are bundled in this
 - Ansible 2.10.x and Mitogen 0.3.x are used to build nearly all images
   (Ansile 2.3.x is retained for CentOS 5, because it uses Python 2.4).
 - Tox is used to install/run Ansible, replacing build_docker_images.py
 - A static inventory, identifying containers by name rather than ID.
 - debian-test image is renamed to debian9-test
 - debian9-test image is now based on debian:9
 - centos6-test image is now based on moreati/centos6-vault
   following the same scheme as centos5-test.
 - Images are now uploaded to Amazon Elastic Container Registry (ECR).
   See #809.
 - Debian recommended packages aren't installed (e.g. build-essential)
 - Python 2.x and Python 3.x are installed wherever available.
 - Python Virtualenv is installed wherever available.

README.md

tests/ansible Directory

This is an an organically growing collection of integration and regression tests used for development and end-user bug reports.

It will be tidied up over time, meanwhile, the playbooks here are a useful demonstrator for what does and doesn't work.

Preparation

See ../image_prep/README.md.

run_ansible_playbook.py

This is necessary to set some environment variables used by future tests, as there appears to be no better way to inject them into the top-level process environment before the Mitogen connection process forks.

Running Everything

ANSIBLE_STRATEGY=mitogen_linear ./run_ansible_playbook.py all.yml

hosts/ and common-hosts

To support running the tests against a dev machine that has the requisite user accounts, the the default inventory is a directory containing a 'localhost' file that defines 'localhost' to be named 'target' in Ansible inventory, and a symlink to 'common-hosts', which defines additional targets that all derive from 'target'.

This allows ansible_tests.sh to reuse the common-hosts definitions while replacing localhost as the test target by creating a new directory that similarly symlinks in common-hosts.

There may be a better solution for this, but it works fine for now.
