ansible_experiment
Ansible post-deployment playbook. It copies the current (git) repository to the
remote host (ignoring the .git and results directories), setups, runs, and
teardowns the experiment, and finally retrieves the result back to the local
computer.
The setup must be located at setup/run and return an absolute path to a
directory which will be used to contain metadata an experiment results. It can
also accept a path, which it may use to determine the results directory. The
experiment script must be located in experiment/run, and accept a path as
argument (that path being the one output by the setup script). teardown
follows the same rules as the experiment script. This playbook only needs the
scripts to follow the same semantics.
The following setup and teardown can be used:
Dependencies
This playbook uses the
synchronize
ansible module which uses rsync internally. This software is needed on the
local machine, and on all remote hosts.
We assume that the setup, experiment and teardown scripts have their
own way of managing their dependencies.
