Ansible Datasaker Role

The Ansible Datasaker role installs and configures the Datasaker Agent and integrations.

Setup

Requirements

• Requires Ansible v2.6+.
• Supports most Debian Linux distributions.
• Supports most RedHat Linux distributions.
• Supports Amazon Linux 2 distributions.

Installation

Install the [Datasaker role] from Ansible Galaxy on your Ansible server:

ansible-galaxy install dsk_bot.datasaker

To deploy the Datasaker Agent on hosts, add the Datasaker role and your API key to your playbook:

*** When installing dsk-log-agent, fluent-bit is automatically installed. ***
