Chapter 2 - Deploy me an OpenStack!

Bring up rest of interfaces

For Ubuntu (also install python)

ansible -m raw -i multinode  -a "apt-get -y install python" all
ansible -i ./multinode -m shell -a "ifconfig ens4 up && dhclient ens4" all
ansible -i ./multinode -m shell -a "ifconfig ens5 up && dhclient ens5" all

For Centos (also disable selinux)

ansible -i ./multinode -m shell -a "ifconfig eth1 up" all
ansible -i ./multinode -m shell -a "ifconfig eth2 up && dhclient" all
ansible -i ./multinode -m shell -a "setenforce 0" all

Install docker and other requirements

Let's start by installation and configuration of Docker, few packages needed by Kolla and preparation of host files. To do that simply run

kolla-ansible -i ./multinode bootstrap-servers

Check if everything is in order

Let's do some preflight checks

kolla-ansible -i ./multinode prechecks

Mark disks for Ceph

We need to point which disks we want to use for Ceph deployment. To do that we need to run this command on storage nodes

parted $DISK -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP 1 -1

Or make Ansible do it!

ansible -i ./multinode -m shell -a "parted /dev/vdb -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP 1 -1" storage

Deploy whole thing

kolla-ansible -i ./multinode deploy
