Automated TripleO upgrades

Upgrading TripleO can be a hard task. While there are instructions on how to do it manually, having a set of playbooks that automate this task can help.
With this purpose, I've created the TripleO upgrade automation playbooks (https://github.com/redhat-nfvpe/tripleo-upgrade-automation).
Those are a set of playbooks that allow to upgrade an existing TripleO deployment, specially focused on versions from 8 to 10, and integrated with local mirrors (https://github.com/redhat-nfvpe/rhel-local-mirrors)

In case you want to know more, please visit the tripleo-upgrade-automation project on github, and you'll get instructions on how to properly use this repo to automate your upgrades.

Deploying and upgrading TripleO with local mirrors

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 file when deployi…

Automating local mirrors creation in RHEL

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 Networkprepare the system to host mirrorscreate the specified mirrorsschedule 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.gitThis playbook expects a group of servers called

Build and use security hardened images with TripleO

Starting to apply since Pike Concept of security hardened images Normally the images used for overcloud deployment in TripleO are not security hardened. It means, the images lack all the extra security measures needed to accomplish with ANSSI requirements. These extra measures are needed to deploy TripleO in environments where security is an important feature.
The following recommendations are given to accomplish with security guidelines:
ensure that /tmp is mounted on a separate volume or partition, and that it is mounted with rw,nosuid,nodev,noexec,relatime flagsensure that /var, /var/log and /var/log/audit are mounted on separates volumes or partitions, and that are mounted with rw,relatime flags.ensure that /home is mounted on a separate partition or volume, and that it is mounted with rw,nodev,relatime flags.include extra kernel boot flag to enable auditing: add audit=1 to GRUB_CMDLINE_LINUX settingdisable kernel support for USB via bootloader configuration: add nousb to GRUB_CMD…
