Containers in OpenStack

Working with Container Orchestration Engines

In this chapter, we will be looking at the Container Orchestration Engine (COE). Container Orchestration Engines are tools which help in managing many containers running on multiple hosts.

In this chapter, we will be covering the following topics:

  • Introduction to COE
  • Docker Swarm
  • Apache Mesos
  • Kubernetes
  • Kubernetes installation
  • Kubernetes hands-on

Introduction to COE

Containers provide users with an easy way to package and run their applications. Packaging involves defining the library and tools that are necessary for a user's application to run. These packages, once converted to images, can be used to create and run containers. These containers can be run anywhere, whether it's on developer laptops, QA systems, or production machines, without any change in environment. Docker and other container runtime tools provide the facility to manage the life cycle of such containers.

Using these tools, users can build and manage images, run containers, delete containers, and perform other container life cycle operations. But these tools can only manage one container on a single host. When we deploy our application on multiple containers and multiple hosts, we need some kind of automation tool. This type of automation is...

Docker Swarm

Docker Swarm is a native orchestration tool from Docker itself. It manages a pool of Docker hosts and turns them into a single virtual Docker host. Docker Swarm provides a standard Docker API to manage containers on the cluster. It's easy for users to move to Docker Swarm if they are already using Docker to manage their containers.

Docker Swarm follows a swap, plug, and play principle. This provides pluggable scheduling algorithms, a broad registry, and discovery backend support in the cluster. Users can use various scheduling algorithms and discovery backends as per their needs. The following diagram represents the Docker Swarm architecture:

Docker Swarm components

The following sections explain the various...

Apache Mesos

Apache Mesos is an open source, fault-tolerant cluster manager. It manages a set of nodes called slaves and offers their available computing resources to frameworks. Frameworks take the resource availability from the master and launches the tasks on the slaves. Marathon is one such framework, which runs containerized applications on the Mesos cluster. Together, Mesos and Marathon become a container orchestration engine like Swarm or Kubernetes.

The following diagram represents the whole architecture:

Apache Mesos and its components

Here is a list of Apache Mesos components:

Master

Kubernetes

Kubernetes is a container orchestration engine created by Google, designed to automate the deployment, scaling, and operating of containerized applications. It is one of the fastest developing COEs because it provides a reliable platform to build distributed applications on a massive scale. Kubernetes automates your application, manages its life cycle, and maintains and tracks resource allocation in a cluster of servers. It can run application containers on physical or virtual machine clusters.

It provides a unified API to deploy web applications, databases, and batch jobs. It comprises of a rich set of complex features:

  • Auto-scaling
  • Self-healing infrastructure
  • Configuration and updating of batch jobs
  • Service discovery and load balancing
  • Application life cycle management
  • Quota management
...

Kubernetes installation

Kubernetes can run on various platforms, from laptops and VMs on a cloud provider to a rack of bare metal servers. There are multiple solutions today to install and run Kubernetes clusters. Read the Kubernetes documentation to find the best solution for your particular use case.

In this chapter, we will use kubeadm to bring up a Kubernetes cluster on Ubuntu 16.04+. kubeadm can be used to easily bring up a cluster with a single command per machine.

In this installation, we will use a tool called kubeadm, which is a part of Kubernetes. The prerequisites for installing kubeadm are:

  • One or more machines running Ubuntu 16.04+
  • Minimum of 1 GB or more of RAM per machine
  • Full network connectivity between all machines in the cluster

All of the machines in the cluster need the following components to be installed:

  1. Install Docker on all of the machines. As per...

Description

Containers are one of the most talked about technologies of recent times. They have become increasingly popular as they are changing the way we develop, deploy, and run software applications. OpenStack gets tremendous traction as it is used by many organizations across the globe and as containers gain in popularity and become complex, it’s necessary for OpenStack to provide various infrastructure resources for containers, such as compute, network, and storage. Containers in OpenStack answers the question, how can OpenStack keep ahead of the increasing challenges of container technology? You will start by getting familiar with container and OpenStack basics, so that you understand how the container ecosystem and OpenStack work together. To understand networking, managing application services and deployment tools, the book has dedicated chapters for different OpenStack projects: Magnum, Zun, Kuryr, Murano, and Kolla. Towards the end, you will be introduced to some best practices to secure your containers and COE on OpenStack, with an overview of using each OpenStack projects for different use cases.

This book definitely hits the spot.There's quite a bit of depth and time given to all aspects of the topic. The authors have been active contributors to the OpenTable projects that they write about, and that shows!All in all, I would highly recommend this book to anyone working towards containers and the private cloud.

It is a quick and easy read, however missing (hopefully in 2nd revision to be covered);(1) machine containers (LXC/LXD) for both deploying openstack with containers and deploying workloads on openstack with nova-lxd hypervisor,(2) totally skipping Helm (no mention on openstack-helm as well) and no reference on kolla-kubernetes dependency on helm,(3) most of the use for containers on openstack is for CI/CD pipelines and no relevant usecase mentioned,(4) no mention on telemetry for container workloads ...ps: I am giving 5 stars still to encourage authors as writing a book is not a easy job...

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
