Continued from http://teknoarticles.blogspot.com.es/2017/08/automating-local-mirrors-creation-in.html In the previous blogpost, I explained how to automate the RHEL mirror creation using https://github.com/redhat-nfvpe/rhel-local-mirrors . Now we are going to learn how to deploy and upgrade TripleO using those. Deploying TripleO Undercloud To use local mirrors in the undercloud, you simply need to get the generated osp<version>.repo that you generated with the rhel-local-mirrors playbook, and copy it to /etc/yum.repos.d/ , in the undercloud host: sudo curl http://<local_mirror_ip>/osp<version>_repo/osp<version>.repo \ -o /etc/yum.repos.d/osp.repo Then proceed with the standard instructions for deploy. Overcloud Each node from the overcloud (controllers, computes, etc...) needs to have a copy of the repository file from our server where we host the local mirrors. To achieve it, you can include an script that downloads the osp<version>.repo fi...

Sometimes there is a need to consume RHEL mirrors locally, not using the Red Hat content delivery network. It may be needed to speed up some deployment, or due to network constraints. I create an ansible playbook, rhel-local-mirrors ( https://github.com/redhat-nfvpe/rhel-local-mirrors ), that can help with that. What does rhel-local-mirrors do? It is basically a tool that connects to the Red Hat CDN, and syncs the repositories locally, allowing to populate the desired mirrors, that can be accessed by other systems via HTTP. The playbook is performing several tasks, that can be run together or independently: register a system on the Red Hat Network prepare the system to host mirrors create the specified mirrors schedule automatic updates of the mirrors How to use it? It is an Ansible playbook, so start by installing it, in any prefered format. Then continue by cloning the playbook: git clone https://github.com/redhat-nfvpe/rhel-local-mirrors.git This playbook exp...
