AIL-framework/ansible

AIL-framework-ansible

This Ansible role can be used to deploy the AIL-Framework on a host.

Usage

• Create a folder called inventories
• In this folder, create an inventory called develop with the following content:

[ail]
<Your server IP(s) separated by newlines>

[ail:vars]
ansible_ssh_private_key_file=<Path to your private SSH key for the server(s)>

• Grab the latest bin/packages/config.cfg.sample file from the AIL repository and modify it to so it fits your needs. Then, place it in roles/ail-host/files/config.cfg.
• Make sure the SSH service is reachable and that python is installed on the remote host(s) for Ansible to work
• Run deploy.sh

Starting/Stopping AIL

All AIL components are available as systemd services.

Use systemctl {start, stop} ail-redis ail-leveldb ail-logging ail-queues ail-scripts ail-flask to start/stop specific services.

To start the AIL components manually, the remote scripts in /opt/AIL-scripts can also be used. They will be present after using the AIL role.

Remote user

By default, this Ansible project requires remote root access. However, if you want to use the become directive of Ansible, you can edit the required files as follows:

• In deploy.sh add --ask-become-pass
• In deploy.yml add:

become: yes
become_user: root

• In group_vars/ail.yml change the remote_user to the user that will escalate privileges on the remote host(s) using sudo.

Updating thirdparty libraries

To deploy AIL, the thirdparty files in the folder var/www/static are shipped along with this project to minimize the risk of unavailable or unexpected files. If you need to update all these dependencies, you can use the script update_thirdparty.sh which is being shipped along with AIL.

Testing

It's possible to test the AIL role locally in a docker environment which is also provided in this repository. Please note that as of this version, this tests the playbook until the systemd services are being activated. To also test the deployment of the systemd services you might use an ubuntu image with systemd support (systemd has to have PID 1).

To test this Ansible playbook, execute these commands:

• Start the testing process: sudo docker build --rm -f Dockerfile.testing -t ail-testing .
