Utility to assist cloning an existing Satellite 6 server to a new host

Satellite-clone

Easily setup a Satellite 6.1, 6.2, or 6.3 server with restored backup data.

Getting Started

Throughout this documentation, ensure that you understand the following terminology:

• Source server: Existing Satellite server.
• Target server: new server, to which Satellite server is being cloned.

What you need:

• A blank (vanilla install) RHEL 7 server (target server). You will run the setup commands here.
• A backup from a 6.1, 6.2, or 6.3 Satellite server (source server) created with katello-backup. This backup can be with or without pulp-data, and can be from a RHEL 6 or 7 machine.
• You will need a Satellite 6 subscription for the cloned machine. With the new Satellite Infrastructure subscription model you should have multiple Satellite subscriptions available.

Setup

On the target server:

1. git clone this project.

     # git clone https://github.com/RedHatSatellite/satellite-clone.git

2. Install ansible package. Ansible should be installed from extras channel.

     # subscription-manager repos --enable rhel-7-server-extras-rpms
     # yum install -y ansible

Now you can proceed to performing the cloning process. Please check our FAQ section for frequently asked questions.

Fact caching

In order to have the functionality of start-at-task and interactive mode, we cache facts so they can be re-used if someone wants to start the playbook at a certain step. The syntax for this looks something like:

- name: Check for config tar file
  stat:
    path: '{{ backup_dir }}/config_files.tar.gz'
    get_checksum: False
    get_md5: False
  register: config_data

- name: set fact - config_data
  set_fact:
    clone_config_data_exists: "{{ config_data.stat.exists }}"
    cacheable: True

Any variable-type data should be stored as a fact and made cacheable. Note that cacheable: True should be set for every fact.
