rhel-repo-sync

Is an ansible playbook allowing you to host multiple Red Hat version repositories all on one (or more) servers. By retrieving and refactoring the SSL certificates and repository information from a given subscribed server(s) thus allowing the host or hosts to be able to syncronise with Red Hat CDN as if it was a subscribed host.

The example below uses two existing Red Hat servers, one RHEL6 and one RHEL7. Both machines have a valid subscription for the repositories we want to host.

Simply configure in the vars the variable servers describing the FQDN and what Red Hat release the server is, and finally a list of the repos you are wanting to to syncronise with Red Hat CDN.

    servers:
      rhel7.internal.lan:
        release: 7Server
        repos:
          - rhel-7-server-rpms
          - rhel-7-server-optional-rpms
          - rhel-7-server-extras-rpms
          - rhel-7-server-supplementary-rpms
          - rhel-ha-for-rhel-7-server-rpms
          - rhel-rs-for-rhel-7-server-rpms
          - rhel-server-rhscl-7-rpms
      rhel6.internal.lan:
        release: 6Server
        repos:
          - rhel-6-server-extras-rpms
          - rhel-6-server-optional-rpms
          - rhel-6-server-rpms
          - rhel-6-server-supplementary-rpms
          - rhel-server-rhscl-6-rpms

You can control the destination location of the repositories base directory by setting the repo_base variable. By default it is set to /var/www/html/repos

A sample redacted structure post execution is:

All configurations used by the reposync command are generated and placed in a directory which is configurable by editing the config_path variable. The default is set to config_path: /etc/reposync and contains a custom yum.conf file, the refactored .repo files, and the SSL certificates. An example:

/etc/reposync/

└── yum.conf

Each .repo file is generated by extracting the INI section and refactoring it from the original redhat.repo file present on the subscribed server. Changes made are that we point the SSL certificates and key to the new path. Hardcode the releasever and set the basearch to x86_64 (May add other architecture options if requested).
