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.

Osquery & Kolide Fleet Architecture Diagram

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

cd /opt
git clone https://github.com/openstack/openstack-ansible-ops

Copy the env.d file into place

cd /opt/openstack-ansible-ops/osquery
cp env.d/fleet.yml /etc/openstack_deploy/env.d/

Copy the conf.d file into place

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

vi /etc/openstack_deploy/conf.d/fleet.yml

Create the containers

cd /opt/openstack-ansible/playbooks
openstack-ansible lxc-containers-create.yml --limit fleet_all

Update the /etc/hosts file (optional)

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.

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.

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.

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
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

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

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.

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.

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.
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.

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.
