insidegroup.ocp_iso_customize

⭐ Star us on GitHub — it motivates us a lot!

Role to manage automatic rhcoreos or coreos creation with kargs and livekargs for Openshift/OKD installations. It has been made to iterate over inventory using bootstrap, masters and workers groups

Platforms Supported:

Platform	Versions
Ubuntu	focal, jammy
Fedora	all

⚠️ Requirements

Ansible >= 2.9.

Due to coreos-installer usage:

• openssl1.1-1.1 (for Fedora)
• libssl1.1 (for Ubuntu)

Ansible role dependencies

None.

⚡ Installation

Install with Ansible Galaxy

ansible-galaxy install insidegroup.ocp_iso_customize

Install with git

If you do not want a global installation, clone it into your roles_path.

git clone https://github.com/InsideCommunity/ocp_iso_customize.git  insidegroup.ocp_iso_customize

But I often add it as a submodule in a given playbook_dir repository.

git submodule add https://github.com/InsideCommunity/ocp_iso_customize.git roles/insidegroup.ocp_iso_customize

As the role is not managed by Ansible Galaxy, you do not have to specify the github user account.

✏️ Example Playbook

Basic usage is:

- hosts: all
  roles:
    - role: insidegroup.ocp_iso_customize
      vars:
        ocp_iso_customize_coreos_img_url: ''
        ocp_iso_customize_coreos_installer_type: podman
        ocp_iso_customize_coreos_installer_url: http://mirror.openshift.com/pub/openshift-v4/x86_64/clients/coreos-installer/latest/coreos-installer
        ocp_iso_customize_dest: /var/www/html/example/images/coreOS
        ocp_iso_customize_dest_device: sda
        ocp_iso_customize_domain: example.com
        ocp_iso_customize_extra_live_karg: ''
        ocp_iso_customize_filer: http://file.example.com/ocp4
        ocp_iso_customize_filer_ignition_path: '{{ ocp_iso_customize_filer }}/example/'
        ocp_iso_customize_kargs: {}
        ocp_iso_customize_output_type: minimal
        ocp_iso_customize_primary_dns: 10.0.10.250
        ocp_iso_customize_role: worker
        ocp_iso_customize_secondary_dns: 8.8.8.8
        ocp_iso_customize_source_iso_url: https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/37.20230122.3.0/x86_64/fedora-coreos-37.20230122.3.0-live.x86_64.iso

⚙️ Role Variables

Variables are divided in three types.

The default vars section shows you which variables you may override in your ansible inventory. As a matter of fact, all variables should be defined there for explicitness, ease of documentation as well as overall role manageability.

The context variables are shown in section below hint you on how runtime context may affects role execution.

Default variables

Role default variables from defaults/main.yml.
