ADEPT, the Deterministic Executor for Parallel Testing

ADEPT includes a small python program and a collection of Ansible playbooks, and related configurations. Together, they help orchestrate parallel creation, configuration, use and cleanup of ephemeral virtual machines.

Prerequisites

  • Red Hat based host (RHEL, CentOS, Fedora, etc), subscribed and fully updated.
  • Python 2.7
  • PyYAML 3.10 or later
  • libselinux-python 2.0 or later
  • rsync 2.5 or later
  • Ansible 2.1 or later (EPEL)
  • Root access not required

Testing/Development

  • Ansible 2.3 or later
  • python-unittest2 1.0 or later
  • python2-mock 1.8 or later
  • pylint 1.4 or later
  • python-virtualenv or python2-virtualenv (EPEL)
  • Optional (for building documentation), make, python-sphinx, and docutils or equivalent for your platform.

OpenStack support:

Quickstart

Ansible 2.3 or later is required, along with the items listed under prerequisites.

This demonstration doesn't do anything extraordinarily useful. However, it does demonstrate ADEPT's essential functions. The tasks to be performed (the job) exist as a sparse standard Ansible directory layout, under jobs/quickstart. All files in the job directory, overwrite identically named files under kommandir/ (after a working copy is made).

# Optional: set $ANSIBLE_PRIVATE_KEY_FILE
# if unset, a new temporary key will be generated in workspace
$ export ANSIBLE_PRIVATE_KEY_FILE="$HOME/.ssh/id_rsa"

# Create a place for runtime details and results to be stored
$ export WORKSPACE="$(mktemp -d --suffix=.workspace)"

# Run the ADEPT-three-step (keyboard finger-dance)
$ ./adept.py setup $WORKSPACE exekutir.xn
$ ./adept.py run $WORKSPACE exekutir.xn
$ ./adept.py cleanup $WORKSPACE exekutir.xn

# Cleanup the workspace, when you're done looking at it.
$ rm -rf $WORKSPACE

Notes:

  1. To see select debugging output (select variable values and infos), append -e adept_debug=true onto any of the adept.py lines above.
  2. Setting -e adept_debug=true will prevent roles in the cleanup context from removing any leftover files in the workspaces.
  3. To see massive amounts of ugly details, append one or more --verbose, options onto any of the adept.py lines above.
