2. Why ARA and How it differs from others?
2.1 Why ARA?
- ARA is a Open Source project and it’s relatively simple application that is very easy to install and configure.
- ARA works by configuring the callback in
ansible.cfg, run a playbook and it’ll be recorded, wherever it is.
- No need of inventory management.
- It just record data and provide an intuitive interface for it.
- ARA stores data locally and browsed locally, no need of central server or upload your data elsewhere.
2.2 How it differs from others?
- Ansible Tower is currently a product from Ansible and has not been open sourced.
- Other tools such as Ansible Tower, Semaphore and Rundeck wants to control the whole workflow from end-to-end.
- The above application need to be hosted and maintained “centralized”.
- ARA does not require any changes to your setup or workflow, it adds itself in transparently and seamlessly.

config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides

3.2 Configuring ansible.cfg
- To use ARA we need to configure
ansibleto know about ARA Installation
- We can use Environmental variables or ansible .cfg file in current directory
- Let’s use ansible.cfg file in current directory
- Add content to
ansible.cfgfile by running the following command
cat > ansible.cfg <<EOF [defaults] # callback_plugins configuration is required for the ARA callback callback_plugins = $ara_location/plugins/callbacks
action_plugins and library configuration is required for the ara_record and ara_read modules action_plugins = $ara_location/plugins/actions library = $ara_location/plugins/modules EOF `
Note: Before adding the above lines to
ansible.cfg just export the variable
export ara_location=$(python -c "import os,ara; print(os.path.dirname(ara.__file__))")
3.3 Configuring Web Server
- ARA comes with embedded web server, set-up environmental variable for
$ export ARA_DATABASE="sqlite:////tmp/ara.sqlite"
$ ara-manage runserver -h 0.0.0.0 -p 8080
- Visit the web-interface page at
host-ip:8080and you could see its not started recording, so we need to run
ansible-playbookat-least once to make ARA to start recording.
- Create a ansible role to install cowsay and configure inventory file for hosts.
- Now run ansible-playbook with configure.yml and inventory file.
- After running ansible-playbook we need to run
ara-manage runserverto start web-interface again.
- We could see the lovely interface of ARA with data collected of playbook-reports
- A complete installation of ARA and for a small demo, just watch the
