Update conditionals and namespaced options
This change implements namespaced variables and conditionals in needed
services. This will ensure systems running these playbooks are able to
be deployed in isolation without making osa specific assumptions.

Install OSQuery and Kolide fleet
################################
:tags: openstack, ansible
About this repository
---------------------
This set of playbooks will deploy osquery and kolide-fleet. If this is being
deployed as part of an OpenStack all of the inventory needs will be provided for.
**These playbooks require Ansible 2.4+.**
Highlevel overview of Osquery & Kolide Fleet infrastructure these playbooks will
build and operate against.

OpenStack-Ansible Integration
-----------------------------
These playbooks can be used as standalone inventory or as an integrated part of
an OpenStack-Ansible deployment. For a simple example of standalone inventory
see ``inventory.example.yml``.
Setup | system configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Clone the osquery-osa repo
.. code-block:: bash
cd /opt
git clone https://github.com/openstack/openstack-ansible-ops
Copy the env.d file into place
.. code-block:: bash
cd /opt/openstack-ansible-ops/osquery
cp env.d/fleet.yml /etc/openstack_deploy/env.d/
Copy the conf.d file into place
.. code-block:: bash
cp conf.d/fleet.yml /etc/openstack_deploy/conf.d/
In **fleet.yml**, list your logging hosts under fleet-logstash_hosts to create
the kolide fleet cluster in multiple containers and one logging host under
`fleet_hosts` to create the fleet container
.. code-block:: bash
vi /etc/openstack_deploy/conf.d/fleet.yml
Create the containers
.. code-block:: bash
cd /opt/openstack-ansible/playbooks
openstack-ansible lxc-containers-create.yml --limit fleet_all
Update the `/etc/hosts` file *(optional)*
.. code-block:: bash
cd /opt/openstack-ansible/playbooks
openstack-ansible openstack-hosts-setup.yml
Create an haproxy entry for kolide-fleet service 8443
Add the following configuration item to the `haproxy_extra_services` variable
within a **user** defined variable file.
.. code-block:: yaml
haproxy_extra_services:
- service:
haproxy_service_name: kolide-fleet
haproxy_ssl: False
haproxy_backend_nodes: "{{ groups['kolide-fleet_all'] | default([]) }}"
haproxy_port: 6443 # This is set using the "kolide_fleet_port" variable
haproxy_check_port: 443 # This is set using the "kolide_fleet_port" variable
haproxy_backend_port: 443 # This is set using the "kolide_fleet_port" variable
haproxy_balance_type: tcp
With the appropriate haproxy configuration in place, setup haproxy to begin
load balancing the traffic.
.. code-block:: bash
cd /opt/openstack-ansible/playbooks/
openstack-ansible haproxy-install.yml
Deploying | Installing with embedded Ansible
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If this is being executed on a system that already has Ansible installed but is
incompatible with these playbooks the script `bootstrap-embedded-ansible.sh` can
be sourced to grab an embedded version of Ansible prior to executing the
playbooks.
.. code-block:: bash
source bootstrap-embedded-ansible.sh
Deploying | Manually resolving the dependencies
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This playbook has external role dependencies. If Ansible is not installed with
the `bootstrap-ansible.sh` script these dependencies can be resolved with the
``ansible-galaxy`` command and the ``ansible-role-requirements.yml`` file.
* Example galaxy execution
.. code-block:: bash
ansible-galaxy install -r ansible-role-requirements.yml --roles-path=~/ansible_venv/repositories/roles
In the even that some of the modules are alread installed execute the following
.. code-block:: bash
ansible-galaxy install -r ansible-role-requirements.yml --ignore-errors --roles-path=~/ansible_venv/repositories/roles
Once the dependencies are set make sure to set the action plugin path to the
location of the config_template action directory. This can be done using the
environment variable `ANSIBLE_ACTION_PLUGINS` or through the use of an
`ansible.cfg` file.
Deploying | The environment
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Create some basic passwords keys that are needed by fleet
.. code-block:: bash
echo "kolide_fleet_db_password: $(openssl rand -base64 16)" >> /etc/openstack_deploy/user_secrets.yml
echo "kolide_fleet_jwt_key: $(openssl rand -base64 32)" >> /etc/openstack_deploy/user_secrets.yml
echo "kolide_fleet_admin_password: $(openssl rand -base64 16)" >> /etc/openstack_deploy/user_secrets.yml
# NOTICE: This may already be defined
echo "kolide_galera_root_password: $(openssl rand -base64 16)" >> /etc/openstack_deploy/user_secrets.yml
Install master/data Fleet nodes on the elastic-logstash containers,
deploy logstash, deploy Kibana, and then deploy all of the service beats.
.. code-block:: bash
cd /opt/openstack-ansible-ops/osquery
ansible-playbook site.yml -e@/etc/openstack_deploy/user_secrets.yml
If the `installOSquery.yml` playbook is executed with a limit, a single
kolide-fleet host must be part of the limit. This requirement exists because
the nodes running osquery require certificates to authenticate to the
kolide-fleet cluster. Should a node within the kolide-fleet cluster not be
part of the limit the playbooks will not be able to fetch the required
certificates.
.. code-block:: bash
ansible-playbook installOSquery.yml $USER_VARS --limit 'host1,host2,kolide-fleet_all[0]'
* The `openstack-ansible` command can be used if the version of ansible on the
system is greater than **2.5**. This will automatically pick up the necessary
group_vars for hosts in an OSA deployment.
* If required add ``-e@/opt/openstack-ansible/inventory/group_vars/all/all.yml``
to import sufficient OSA group variables to define the OpenStack release.
* Alternatively if using the embedded ansible, create a symlink to include all
of the OSA group_vars. These are not available by default with the embedded
ansible and can be symlinked into the ops repo.
.. code-block:: bash
ln -s /opt/openstack-ansible/inventory/group_vars /opt/openstack-ansible-ops/osquery/group_vars
The individual playbooks found within this repository can be independently run
at anytime.
Local testing
-------------
To test these playbooks within a local environment you will need a single server
with at leasts 8GiB of RAM and 40GiB of storage on root. Running an `m1.medium`
(openstack) flavor size is generally enough to get an environment online.
To run the local functional tests execute the `run-tests.sh` script out of the
tests directory. This will create a single node kolide-fleet cluster and install
osquery on the local host.
.. code-block:: bash
CLUSTERED=yes tests/run-tests.sh
To rerun the playbooks after a test build, source the `tests/manual-test.rc`
file and follow the onscreen instructions.
To clean-up a test environment and start from a bare server slate the
`run-cleanup.sh` script can be used. This script is disruptive and will purge
all `osquery` related services within the local test environment.
.. code-block:: bash
tests/run-cleanup.sh
