Topics

•Hardware •OpenStack Repository •Bare-metal Provisioning •Packstack •Questions

Hardware

•IBM x3455 •1 x Provisioning Node

•3 x Controllers

•6 x Hypervisors

•Cisco Switch

Yum repositories

•Use reposync to sync repos •Main repos used for Open-source

•CentOS Updates

•CentOS Extras

•EPEL

•RDO OpenStack (icehouse, juno & kilo)

•Also use reposync for rhel

Sync’ing Repos

•Create /etc/reposync.d/yum.conf •Create repo files similar to the ones for yum for all the repos

•For Red Hat •Register machine to RHN

•Then use reposync to sync the following repos •rhel-7-server-openstack-5.0-rpms

•rhel-7-server-openstack-6.0-rpms

•rhel-7-server-rpms

•rhel-ha-for-rhel-7-server-rpms

•rhel-7-server-optional-rpms

reposync

•-t •Use a temp dir for storing/accessing yum-cache.

•-d •Delete local packages no longer present in repository.

•-n •Download only newest packages per-repo.

•-p •Path to download packages to: defaults to current directory.

•-r •Specify repo ids to query, can be specified multiple times (default is all

enabled).

•-c •Config file to use (defaults to /etc/yum.conf).

Reposync example

yum -c /etc/reposync.repos.d/yum.conf clean all

reposync -t -d -n -c /etc/reposync.repos.d/yum.conf

-p /install/post/otherpkgs/repos/ -r epel-7 -r

foreman-7 -r rdo-openstack-icehouse-epel-7 -r rdo-

openstack-kilo-epel-7 -r updates-7 -r rdo-openstack-

juno-epel-7 -r rdo-openstack-kilo-el-7

For each of the repos downloaded, we then need to run

createrepo, to enable the directory for yum download

Bare-metal provisioning (xCAT)

•eXtreme Cluster/Cloud Administration Toolkit •Management of clusters (Clouds, HPC, Grids)

•Open-Source (EPL License)

•IPMI (Inventory, HW Control, SOL, LEDs, etc…)

•Discovery

•Multiple Installation Methods

•Wide system and OS support

Packstack

•Deploy of OpenStack •Puppet

•Requires pre-installed machines with SSH access

•No HA support •PoC
