Vagrant file to deploy Ceph on OpenShift

vagrant + libvirt hostconfig

Install vagrant + vagrant-libvirt:

sudo yum install -y qemu libvirt libvirt-devel ruby-devel gcc qemu-kvm python-pip
sudo rpm -i https://releases.hashicorp.com/vagrant/2.0.1/vagrant_2.0.1_x86_64.rpm
vagrant plugin install vagrant-libvirt

Make sure your vagrant-libvirt net interface as the same content (will do the dns resolution):

sudo virsh net-dumpxml vagrant-libvirt
<network connections='3' ipv6='yes'>
  <name>vagrant-libvirt</name>
  <uuid>becf31bb-45c8-401e-b68a-cba0962dad3a</uuid>
  <forward mode='nat'>
    <nat>
      <port start='1024' end='65535'/>
    </nat>
  </forward>
  <bridge name='virbr1' stp='on' delay='0'/>
  <mac address='52:54:00:f1:e1:c7'/>
  <domain name='example.com' localOnly='yes'/>
  <ip address='192.168.121.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.121.1' end='192.168.121.254'/>
    </dhcp>
  </ip>
</network>

The line to add is: <domain name='example.com' localOnly='yes'/>

Then:

sudo virsh net-edit vagrant-libvirt
sudo virsh net-destroy vagrant-libvirt
sudo virsh net-start vagrant-libvirt
sudo systemctl restart libvirtd

Vagrant up!

Close OS repo:

git clone https://github.com/openshift/openshift-ansible/
cd openshift-ansible
git checkout release-3.11
git clone https://github.com/leseb/oc-ceph
mv oc-ceph/* .
pip install -r requirements.txt

Simply run:

vagrant up

Note that vagrant provision --provision-with can be useful to run only a subset of sequence:

  • prereq-oc -> node pre-requisite to run OpenShift
  • deploy-oc -> deploy OpenShift
  • deploy-ceph - pending upstream

Wait wait wait until you see:
