Ansible playbook that creates a three-node OpenStack lab environment according to OpenStack Installation Guide for RHEL, CentOS, and Fedora

Bootstraping networking

Before we can run the OpenStack playbook on the nodes, we must prepare the networking on the nodes.

A few minimal manual steps has to be done before bootstraping the networking in the machines:

1. Ensure eth0 comes up; i.e.

   echo '' > /lib/udev/rules.d/75-persistent-net-generator.rules

   echo '' > /etc/udev/rules.d/70-persistent-net.rules

2. Disable SELINUX; i.e. sed -ie 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

3. Disable firewall; i.e. chkconfig iptables off; chkconfig ip6tables off

4. root is able to ssh using a private key; i.e. the public key is added to /root/.ssh/authorized_keys

Once the machines are ready and running, edit the bootstrap-network-inventory.ini file and update the current DHCP-assigned IPs. This allows the bootstrap-network.yml playbook to hit each box and configure the network automatically for you.

% ansible-playbook -i bootstrap-network-inventory.ini bootstrap-network.yml

Few other things

• % yum install -y libselinux-python

Running the OpenStack playbook

Before running the playbook, copy the passwords.yml.template file to passwords.yml and update the passwords and other information in that file.

To run the playbook, run the following command:

  % ansible-playbook -i open-stack-inventory.ini open-stack-playbook.yml --extra-vars @passwords.yml --ask-vault-pass
