conversations.value: Containerization with LXC
  Let's demonstrate a Sensu deployment with an agent inside the LXC container first, then move on to an agentless monitoring.
  At a minimum, we need five configuration files, one for the Sensu API endpoint, two that specify what transport we are using - RabbitMQ in this case - the Redis config file for Sensu, and a client config file, for the Sensu client running on the same server. The following config files are pretty much self-explanatory - we specify the IP addresses and ports of the RabbitMQ and Redis servers, along with the API service:
  In the configuration file, we specify the address and port of the Sensu API service - localhost and port `4567` \- and the port Uchiwa will be listening on - `3000` \- in this case:
  With the Sensu server now fully configured, we need to attach to a container on the host and install the Sensu agent:

conversations.value: It's time to install the Nova packages that will provide the API, the conductor, the console, and the scheduler services:
  Since we are going to use a single node for this OpenStack deployment, we need to install the `nova-compute` service. In production, we usually have a pool of compute servers that only run that service.
  Use the following minimal configuration file, which will allow running `nova-compute` and the rest of the Nova services on the same server:

conversations.value: In this chapter, we saw examples on how to deploy containers with alternative technologies to LXC such as OpenVZ and Docker.
  OpenVZ is one of the oldest container solutions, and as of this writing it's being rebranded to Virtuozzo. The main difference between LXC and OpenVZ is the custom Linux kernel that OpenVZ runs on. It's based on the Red Hat kernels and soon will be shipped as a single installation ISO as compared to the packaged kernel and userspace tools we used in the earlier examples.
  Docker is the de-facto standard and an adoption leader in the containerized world. Being one of the newer containerization technologies, its ease of use, and available API makes it an ideal solution for running microservices in a mass scale. Docker does not need a patched kernel to work, and the availability of centralized registries to store container images makes it a great choice in many scenarios.
  We ended the chapter by showing an example of how to run unprivileged LXC containers. This feature is relatively new, and it's a step in the right direction when it comes to container security.
