TripleO Manual Setup

Intro

Manually setup TripleO on a single baremetal by running Quickstart to create the environment and following TripleO docs for the manual installation.

Quickstart is ONLY used for creating the environment and emulate the baremetal servers.

Disclaimers:

  • This doc includes quick steps to deploy tripleo manually in a single baremetal server using virtual nodes
  • This is not intended to replace official documentation
  • It should work with current master commit 7e834e1 of https://github.com/openstack/tripleo-quickstart

Prep

Environment

  • Deployer machine (where you run quickstart from): deployer@$VIRTHOST
  • Undercloud server: undercloud (libvirt guest)
  • Overcloud controller: control_0 (libvirt guest)
  • Overcloud compute: compute_0 (libvirt guest)

User management

On $VIRTHOST:

  • Create non-root user: sh $ useradd deployer
  • Create /etc/sudoers.d/deployer with: deployer ALL=(ALL) NOPASSWD:ALL
  • Log in as depoyer: sh $ su - deployer
  • Create ssh key, add to root's authorized_keys and ensure you can: ssh [email protected] 'uname -a'

Create Environment

  • Clone quickstart: 
    $ git clone https://github.com/openstack/tripleo-quickstart.git
$ cd tripleo-quickstart
  • Install deps 
    $ bash quickstart.sh --install-deps
  • Run quickstart to only create libvirt guests (TripleO won't be configured) on localhost (use loopback address 127.0.0.2) 
    $ bash quickstart.sh --tags all --playbook quickstart.yml 127.0.0.2

Check Environment

  • Check libvirt guests created for stack user: 
    $ ssh -i ~/.quickstart/id_rsa_virt_host [email protected]
$ virsh list --all
Id    Name                           State
----------------------------------------------------
1     undercloud                     running
-     compute_0                      shut off
-     control_0                      shut off

✅ Environment is ready for configuring TripleO in the libvirt guests created.

Undercloud Installation

Steps include:

  • Access undercloud VM
  • Set up undercloud hostaname
  • Configure repositories
  • Generate undercloud config
  • Install undercloud

Access the undercloud

ssh -F $HOME/.quickstart/ssh.config.ansible undercloud

Set up hostname

sudo hostnamectl set-hostname undercloud.localdomain
sudo hostnamectl set-hostname --transient undercloud.localdomain

Add it to /etc/hosts:

127.0.0.1   undercloud.localdomain undercloud

Set up repository

:squirrel: Note: Use latest stable branch

Access https://trunk.rdoproject.org/centos7/current/ and configure repos for the desired release. For Pike:

sudo yum install -y https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-<version>.el7.centos.noarch.rpm
sudo tripleo-repos -b pike current
sudo yum install -y python-tripleoclient

Generate config

Generate ~/undercloud.conf using this tool: http://ucw-bnemec.rhcloud.com/. Use default settings.

Install undercloud

Install the undercloud:

$ openstack undercloud install

You should see at the end of the installation the following message:

#############################################################################
Undercloud install complete.

Overcloud Installation

Steps include:

  • Build Images
  • Upload images
  • Set up DNS
  • Create and start a virtual BMC for each domain
  • Introspect nodes
  • Make nodes available to deploy
  • Deploy overcloud

Source undercloud credentials

$ source stackrc

Build Image (ignore cached images)

export DIB\_YUM\_REPO\_CONF="/etc/yum.repos.d/delorean\*"
export STABLE\_RELEASE="pike"
mv overcloud-full\* /tmp
mv ironic-python-agent\* /tmp

openstack overcloud image build --no-skip

Upload images

(undercloud) [stack@undercloud ~]$ openstack overcloud image upload

Create a virtual BMC for each domain

[deployer@rdo-ci-fx2-02-s5 ~]$ ssh [email protected]

sudo yum install -y https://trunk.rdoproject.org/centos7/current/python2-tripleo-repos-0.0.1-0.20171116021457.15e17a8.el7.centos.noarch.rpm
sudo tripleo-repos -b pike current

sudo yum install -y python-virtualbmc ipmitool

 -     control_0                      shut off

Start virtual BMCs

[stack@rdo-ci-fx2-02-s5 ~]$ vbmc start compute_0
[stack@rdo-ci-fx2-02-s5 ~]$ 2017-11-15 08:26:22,833.833 74245 INFO VirtualBMC [-] Virtual BMC for domain compute_0 started
