InfraRed for deploying OpenStack

InfraRed is tool that allows to install/provision OpenStack. You can find the documentation for the project at http://infrared.readthedocs.io.

Also, developers and users are online in FreeNode at #infrared channel.

Why InfraRed?¶

Deploying OSP with OSP-d (TripleO) requires several setup steps for preparation, deployment, etc. InfraRed simplifies them by automating with ansible most of those steps and configuration.

It allows to deploy several OSP versions
Allows to ease connection to installed vm roles (Ceph, Computes, Controllers, Undercloud)
Allows to define working environments so one InfraRed-running host can be used to manage different environments
and much more…

Setup of InfraRed-running host¶

Setting InfraRed is quite easy, at the moment the version 2 (branch on github) is working pretty well.

We’ll start with:

Clone GIT repo: git clone https://github.com/redhat-openstack/infrared.git
Create a virtualenv so we can proceed with installation, later we’ll need to source it before each use. cd infrared ; virtualenv .venv && source .venv/bin/activate
Proceed with upgrade of pip and setuptools (required) and installation of InfraRed
pip install --upgrade pip
pip install --upgrade setuptools
pip install .

Remote host setup¶

Once done, we need to setup the requirements on the host we’ll use to virtualize, this includes, having the system registered against a repository providing required packages.

Register RHEL7 and update:
subscription-manager register (provide your credentials)
subscription-manager attach --pool= (check pool number first)
subscription-manager repos --disable=*
for canal in rhel-7-server-extras-rpms rhel-7-server-fastrack-rpms rhel-7-server-optional-fastrack-rpms rhel-7-server-optional-rpms rhel-7-server-rh-common-rpms rhel-7-server-rhn-tools-rpms rhel-7-server-rpms rhel-7-server-supplementary-rpms rhel-ha-for-rhel-7-server-rpms;do subscription-manager repos --enable=$canal; done

NOTES¶

OSP7 did not contain RPM packaged version of images, a repo with the images needs to be defined like:
time infrared tripleo-undercloud --version $VERSION --images-task import --images-url $REPO_URL

!!! note “Check the parameter values” —images-task import and --images-url

Ceph failed to install unless --storage-backend ceph was provided (open bug for that)

Error reporting¶

IRC or github

RFE/BUGS¶

Some bugs/RFE on the way to get implemented some day:

Allow use of localhost to launch installation against local host
Multi env creation, so several OSP-d versions are deployed on the same hypervisor but one launched
Automatically add --storage-backend ceph when Ceph nodes defined

Using Ansible to deploy InfraRed¶

This is something that I began testing to automate the basic setup, still is needed to decide version to use, and do deployment of infrastructure VM’s but does some automation for setting up the hypervisors.

- hosts: all
  user: root

  tasks:
    - name: Install git
      yum:
        name:
          - "git"
          - "python-virtualenv"
          - "openssl-devel"
        state: latest

    - name: "Checkout InfraRed to /root/infrared folder"
      git:
        repo: https://github.com/redhat-openstack/infrared.git
        dest: /root/infrared

    - name: Initialize virtualenv
      pip:
        virtualenv: "/root/infrared/.venv"
        name: setuptools, pip

    - name: Upgrade virtualenv pip
      pip:
        virtualenv: "/root/infrared/.venv"
        name: pip
        extra_args: --upgrade

    - name: Upgrade virtualenv setuptools
      pip:
        virtualenv: "/root/infrared/.venv"
        name: setuptools
        extra_args: --upgrade

    - name: Install InfraRed
      pip:
        virtualenv: "/root/infrared/.venv"
        name: file:///root/infrared/.

This playbook will do checkout of git repo, setup extra pip commands to upgrade virtualenv’s deployed pip and setuptools, etc.
