Jesse Pretorius 954f8ff8cb Add AIO diagnostics and better gate scripts consistency

Implements extra diagnostic information for gate check failure analysis and
also appends DNS settings instead of replacing them for the AIO bootstrap.

Some extra settings are added to the DNS to try to catch edge cases for DNS
resolution. The DNS `resolv.conf` was being overwritten on every run using
google name servers however we need to add google name servers to the existing
resolver not overwrite the whole conf so a conditional was added.

The gate scripts were attempting to create a symlink to logs on every run.
While this is fine for the gate which is creates a new node on every run
the link will cause failures on recheck when doing more local testing.

The ansible log entry was being appended to the `ansible.cfg` file on every
run which should also be limited to one entry. The conditional added is
helpful when doing local testing with the gate scripts.

OpenStack Ansible Deployment

date: 2015-02-02 22:00
tags: lxc, openstack, cloud, ansible
category: *nix

Playbooks

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 part 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 and openstack_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

Notes

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 the lxc-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 the playbooks/ansible.cfg file.

Bugs and Blueprints

Everything we do is in launchpad and gerrit. If you'd like to raise a bug, feature request, or are looking for ways to contribute please go to "https://launchpad.net/openstack-ansible".

Documentation

While no os-ansible-deployment community documentation exists (yet), other than the .rst files present in this repository, comprehensive installation guides for Rackspace Private Cloud (an opinionated version of os-ansible-deployment) are available at "http://www.rackspace.com/knowledge_center/getting-started/rackspace-private-cloud".

Note:: These docs may not be up-to-date with the current release of this repository however they are still a good source of documentation.
