A Skeleton for developing Ansible Code for while-true-do.io.
Creating a repository is always somewhat interesting and needs a lot explanation. This repository should help to reduce the effort and prepare a ready-to-use environment.
This repository consists of several guidance and skeletons for Ansible:
- provide template for new ansible roles
- provide defaults for new ansible roles
- provide steps for new ansible roles
- provide guidance for ansible new roles
You can find the while-true-do.io conventions in the docs.
Install from Github
git clone https://github.com/while-true-do/ansible-skeleton.git
Before creating a new role, please read the below information very carefully. They will explain, how a new role should look like and which steps are needed.
The recommended and portable way to install Ansible is via virtualenv.
# Create a new virtualenv
virtualenv $env_name
# Activate virtualenv
source $env_name/bin/activate
# Install Ansible
pip install ansible
On some selinux enabled systems like Fedora, you have to symlink the selinux site-packages manually.
# Search local site-packages
find /usr/lib64 -iname "*selinux*"
# Now you have to symlink the selinux directory and the python-c-bindings
# Example:
cd $env_name
ln -s /usr/lib64/python3.7/site-packages/_selinux.cpython-37m-x86_64-linux-gnu.so ./lib/python3.7/site-packages/selinux
ln -s /usr/lib64/python3.7/site-packages/_selinux.cpython-37m-x86_64-linux-gnu.so ./lib/python3.7/site-packages/_selinux.cpython-37m-x86_64-linux-gnu.so
Furthermore, selinux requires you to allow docker to manage cgroups.
setsebool -P container_manage_cgroup on
Ansible configuration can be done in multiple files, depending on your needs.
# Edit system ansible.cfg
sudo vi /etc/ansible/ansible.cfg
# Edit user ansible.cfg
vi ~/.ansible.cfg
# Add one to the specific role
vi ansible.cfg (in the current directory)
You have to add the following lines:
[galaxy]
role_skeleton = <path_to_ansible-skeleton>/role
role_skeleton_ignore = ^.git$,^.*/.git_keep$
Molecule must be installed in the same virtualenv (see above).
# Activate virtualenv
source $env_name/bin/activate
# Install molecule and docker support
pip install molecule[docker]
Some manual steps are needed to create new role from scratch.
# Step 1: Create Directory from skeleton
ansible-galaxy init $role_name
mv $role_name while_true_do.$role_name
# Step 2: Review and Modify all "TODO" steps
grep -r "TODO" while_true_do.$role_name
Testing is key for new roles. You want to get comfortable with the Ansible Testing Convention.
This repository is not tested.
