novafloss/ansible-setup

ansible-setup is a standalone bash script providing setup functions for ansible and lxc/lxd, which we use to test ansible playbooks, with the following constraints:

• automatic lxc/lxd basic configuration for ubuntu users only, including travis
• resolvable containers: host should resolve name.lxc and name.lxd
• install ansible in a virtualenv to support having several versions installed
• speed: avoid paramiko dependency, use apt python crypto binaries
• modularity: using bash functions
• hack: support installing particular revisions of ansible for happy hacking

Why ?

With this, we can setup the necessary environment to run the novafloss boot roles which we use for testing, locally, on our jenkins servers or even on travis for open source roles.

Upgrading from setup.sh

Previously, we had a straightforward setup.sh script supporting one of our team's use-case and distribution. Now that our userbase has grown, new feedback has been collected, leading to this new version.

To upgrade, run any of the following examples, but feel free to delete any leftover from setup.sh:

# Uninstall
rm -rf ~/.ansible-env ~/.ansible-setup
unlink ~/.ansible.cfg
sed -i '/source.*ansible-env/d' ~/.bashrc

# Reinstall
wget https://raw.githubusercontent.com/novafloss/ansible-setup/master/ansible-setup
bash ansible-setup ansible_ref_require devel /usr/bin # or use stable-2.1 here
bash ansible-setup lxc_python2_require

If you still want automatic virtualenv activation:

echo source ~/.ansible-env/bin/activate >> ~/.bashrc

Examples

Download the script:

wget https://raw.githubusercontent.com/novafloss/ansible-setup/master/ansible-setup
chmod +x ansible-setup

Unattented lxc install on ubuntu:

./ansible-setup lxc_require

Unattended lxd install on ubuntu:

./ansible-setup lxd_require

Install ansible branch stable-2.1 in /usr/bin with the virtualenv in ~/.ansible-env:

./ansible-setup ansible_ref_require stable-2.1 /usr/bin
ansible --version  # would show 2.1

Install ansible devel in a virtualenv in ~/.ansible-devel:

VIRTUALENV_PATH=~/.ansible-devel ./ansible-setup ansible_ref_require devel
~/.ansible-devel/bin/ansible --version  # would show 2.2

In the same fashion, install the python2-lxc module:

./ansible-setup lxc_python2_require

Or, in a different virtualenv:

VIRTUALENV_PATH=~/.ansible-devel ./ansible-setup lxc_python2_require

If you still want automatic virtualenv activation:

echo source ~/.ansible-env/bin/activate >> ~/.bashrc
# Or if you used VIRTUALENV_PATH=~/.ansible-devel:
echo source ~/.ansible-devel/bin/activate >> ~/.bashrc
