ansible-leapp

This Ansible role attempts to perform an automated in-place upgrade of EL based systems, primarily Red Hat Enterprise Linux.

It performs the following high level tasks:

• Validating prerequisites and requirements
• Preparing a system for the upgrade
• Generate leapp preupgrade report
• Remediate common upgrade issues (disabled by default)
• Performing the upgrade (disabled by default)
• Verifying the post-upgrade state (disabled by default)

By default, this role will not perform the actual upgrade. It is intended to prepare the system and generate a preupgrade report that should be reviewed. If you're feeling lucky, you can also have it attempt to perform the upgrade.

TODO

• Implement post-upgrade verification (tasks/verify.yml)

Dependencies

There are no dependencies to use this role, however, this role assumes you have implemented a standard operating environment that provides:

• Red Hat Enterprise Linux 7
• System Entitled with RHSM or Satellite
• Repositories configured and enabled for latest updates, specifically for rhel-7-server-rpms and rhel-7-server-extras-rpms

Additionally, you must also download the additional required data files (RPM package changes and RPM repository mapping) attached to the Knowledgebase Article and place it in the 'files' directory in the same directory as the playbook including this role.
