ansible-role-odroid

Slightly modified hannseman/ansible-raspbian roles to be compatible with a Ordoird(Ubuntu 18.04) device. It should also work with any other Debian based system.

It will:

• Install specified system packages.
• Configure hostname.
• Configure locale.
• Mount tmpfs on write-intensive directories to increase the lifespan of SD-card.
• Change the password on default user.
• Set the default editor.
• Setup a secure SSH configuration.
• Configure Postfix to send email through an SMTP relay.
• Enable unattended-upgrades.
• Configure Logwatch to send weekly reports.

It will not:

• Update system packages.
• Run apt-get update. Please do this in a pre_task. See Example Playbook.
• Install security patches but unattended-upgrades should take care of that.

Setup

• Flash SD-card with odroid Ubuntu.
• Run playbook.
