There are several playbooks within that will setup hosts for use in OpenStack Cloud. The playbooks will enable LXC on hosts and provides the ability to deploy LXC containers for use within openstack.
- Plays:
setup-hosts.yml
Performs host setup for use with LXC in the OpenStack hosts.setup-infrastructure.yml
Performs all of the setup for all infrastructure components.setup-openstack.yml
Performs all of the setup for all of the OpenStack components.
- If you dont want to run plays individually you can simply run
setup-everything.yml
which will perform all of the setup and installation for you.
- Basic Setup:
- If you have any roles that you'd like to have pulled in that are outside the scope and or replace modules within this repository please add them to the
ansible-role-requirements.yml
file. In this file you will want to fill in the details for the role you want to pull in using standard ansible galaxy format.
- name: SuperAwesomeModule src: https://github.com/super-user/SuperAwesomeModule version: master
- Run the
./scripts/bootstrap-ansible.sh
script, which will install, pip, ansible 1.9.x, all of the required python packages, and bring in any third party ansible roles that you may want to add to the deployment. - Copy the
etc/openstack_deploy
directory to/etc/openstack_deploy
. - Fill in your
openstack_deploy/openstack_user_config.yml
,openstack_deploy/user_secrets.yml
andopenstack_deploy/user_variables.yml
files which you've just copied to your/etc/
directory. - Generate all of your random passwords executing
scripts/pw-token-gen.py --file /etc/openstack_deploy/user_secrets.yml
. - Accomplish all of the host networking that you want to use within the deployment. See the
etc/network
directory in this repository for an example network setup. - When ready change to the
playbooks/
directory and execute your desired plays. IE:
openstack-ansible setup-everything.yml
- If you have any roles that you'd like to have pulled in that are outside the scope and or replace modules within this repository please add them to the
- If you run the
./scripts/bootstrap-ansible.sh
script a wrapper script will be added to your system that wraps the ansible-playbook command to simplify the arguments required to run openstack ansible plays. The name of the wrapper script is openstack-ansible. - The lxc network is created within the lxcbr0 interface. This supports both NAT networks as well as more traditional networking. If NAT is enabled (default) the IPtables rules will be created along with the interface as a post-up processes. If you ever need to recreate the rules and or restart the dnsmask process you can bounce the interface IE:
ifdown lxcb0; ifup lxcbr0
or you can use thelxc-system-manage
command. - The tool
lxc-system-manage
is available on all lxc hosts and can assist in recreating parts of the LXC system whenever its needed. - Inventory is generated by executing the
playbooks/inventory/dynamic_inventory.py
script. This is configured in theplaybooks/ansible.cfg
file. - If you don't use the pw-token-gen.py script you will want to ensure the permissions on /etc/openstack_deploy/user_secrets.yml are more secure.
chmod 0600 /etc/openstack_deploy/user_secrets.yml
