Ansible Convert2RHEL Collection

Overview

This collection provides Ansible roles you can use to perform conversion using the Convert2RHEL framework. Use these roles as the foundation of your conversion automation solution.

Please check the release section of the repository to find information about the latest updates and publication to the Ansible Galaxy.

Roles

These are the roles included in the collection. Follow the links below to see the detailed documentation and example playbooks for each role.

• analysis - executes the convert2rhel analysis phase
• common - used for local logging, mutex locking, and common vars
• handle_c2r_report - reads convert2rhel results and checks for inhibitors
• convert - executes the convert2rhel OS conversion

Example playbooks

Example playbooks can be found here.

Installing the collection from Ansible Galaxy

You can install the collection from Ansible Galaxy by running ansible-galaxy collection install infra.convert2rhel.

You can also include it in a requirements.yml file and install it with ansible-galaxy collection install -r requirements.yml, using the format:

---
collections:
  - name: infra.convert2rhel

Note that if you install the collection from Ansible Galaxy, it will not be upgraded automatically when you upgrade the ansible package. To upgrade the collection to the latest available version, run the following command:

ansible-galaxy collection install infra.convert2rhel --upgrade

You can also install a specific version of the collection, for example, if you need to downgrade when something is broken in the latest version (please report an issue in this repository). Use the following syntax to install version 1.0.0:

ansible-galaxy collection install infra.convert2rhel:==1.0.0

See Using Ansible collections for more details.

Testing

For testing, you have two options. Use manually provisioned machine and run the playbook manually or use the automated way using Makefile and molecule plugin.

Manually provisioned machine

• Provision machine (e.g. using vagrant). This can be done by vagrant init eurolinux-vagrant/centos-7 or by using Vagrantfile. Capture it's IP and directory where you are running this command.
• Move to infra.convert2rhel and create needed folders for ansible by running make create-folder-for-test. This will create structure of directories ansible needs. Remember, you need to run this command each time you change something in the project.
• Run export ANSIBLE_COLLECTIONS_PATH=$(pwd) to set where should ansible look for the expected dir structure.
• Create file in which you will specify hosts to run the ansible playbook. E.g. the file is created in playbook/ called hosts and contain:

[testing]
<IP-of-the-machine> ansible_python_interpreter=/usr/bin/python2.7

Note: the specified ansible_python_interpreter is mainly for easier debugging if you have the correct version of ansible-core (2.16.11), without this you can get a bit confusing error message. Note: if you want to subscribe the system, you can replace the config file by credentials you have in the analysis/tasks/analysis-c2r.yml or convert/tasks/main.yml

• Run the ansible playbook you want using:

ansible-playbook --private-key <path-where-vagrant-was-called>/.vagrant/machines/default/libvirt/private_key -i <specified-hosts> <playbook-path> -u root -vv

e.g.

ansible-playbook --private-key ~/vagrant-box/vagrant/.vagrant/machines/default/libvirt/private_key -i playbooks/hosts playbooks/analysis.yml -u root -vv

Automated way

TBD

Reporting issues

Please open a new issue for any bugs or security vulnerabilities you may encounter. We also invite you to open an issue if you have ideas on how we can improve the solution or want to make a suggestion for enhancment.
