Ansible can be installed directly in your system, but I do not recommend it.
From my perspective, the best idea is to install Ansible in Virtualenv.
This is giving the possibility to use different version of Ansible, what can be
very useful sometimes. Also, this gives a possibility to install all needed
packages in closed environment.
So, let's prepare the Virtualenv.
First, create the file requirements.txt with all needed packages.
Packages can be just like in our example, and this mean that the newest
version will be installed. Other way is to keep the package version:
boto==2.49.
Put into this file two packages:
ansible
boto
Ansible is obvious, I hope, boto is the Python library for working with
AWS.
In case you don't have virtualenv installed you can install it via pip install virtualenv
Now, copy the setupenv.sh file to your project directory, and run it.
So, now the environment should be ready, with Ansible and boto installed (with all needed dependencies).
How to run this environment?
Simply run . ansible/bin/activate. You should see the (ansible) before
your prompt.
In order quit, execute deactivate.
You should run all commands related to this tutorial from this virtualenv.
Ansible can use three locations for config file.
- /etc/ansible/ansible.cfg
- /home/$USER/ansible.cfg
- /your_project_root_dir/ansible.cfg
So, let's create the config file specific for this the project in the project
root directory.
Referring to example from this Chapter, there are two sections:
- defaults
- ssh_connection
Defaults section is most common, and in ssh_connection is responsible for
making Ansible faster. In theory. I'll back to it later.
(There is known issue with creating a $HOME directory by Ansible. You can
simply delete it.)
