09:50 CET

Immutable infrastructure, containers & the future of microservices

Many current trends in software development and deployment are based around the concept of microservices, small independent services interconnected via application programming interfaces (APIs).

The concept of immutable infrastructure is another area of application life cycle that’s gaining attention. In immutable infrastructure, we deploy immutable components that are replaced each time we deploy instead of in-place upgrades.

In this session, we’ll discuss the use of containers as a delivery mechanism for microservices following the immutable infrastructure paradigm. We’ll show this in the context of Project Atomic and OpenShift.

Hands-on introduction to docker for absolute beginners. You can come and watch the presentation, but you will get the most out of it if you bring your own laptop and do the steps on your own. In the meantime before the workshop you can have a look at this page to see how to get Docker on your computer.

This talk will focus on a roadmap for longer-term (1-2 years) changes to make to drive container awareness deeper into the traditional package distribution model. For example:

- Support for non-root containers using RPMs
- The role of systemd on the host and inside containers, particularly "microservices" vs systemd-in-container
- The role of SELinux policy
- How to maintain the advantages of packaging, such as system/cluster wide updates

Comparing Docker Orchestration Tools

Feedback Survey

As we scale to run containers from dev environment to multi-host production environment, we need tools to orchestrate the container deployment. Some of the tools are :-

- Docker Swarm
- Kubernetes
- Mesos

We would use pre-baked Vagrant VMs with the above tools installed on them and then deploy same apps on all of them one by one. After that we’ll do the comparative study.

For reference I have done a tutorial at LinuxCon EU’15 using Vagrant

A New Way to Use OpenStack - OpenStack in Containers

Feedback Survey

OpenStack is a fast growing and complicated project that can run into issues because of its immense complexion, but now, containers have arrived on the scene and they are levelling the playing field. About a month ago, the Kolla project, a newly adopted project in OpenStack, completed its stable release of a containerized OpenStack installer powered by Ansible.

In this session, I would like to discuss how containers improve OpenStack and introduce the Kolla project with the goal of reducing the confusion and malaise that can sometimes come when installing and using a complex tool like OpenStack.

Docker for Developers

Feedback Survey

Docker is not just for deployment. As a developer, there are many ways Docker can make you more productive, regardless of how your app gets deployed.

In this session, you will learn practical strategies for using Docker, including how to:

- Run unit tests locally in multiple environments with almost no overhead.
- Make your integration tests easy for anyone to run by distributing them in a Docker image.
- Simulate advanced network topologies, especially for a service-oriented architecture.
- Make a Docker image in 5 minutes or less that produces builds from a consistent environment.
- Isolate database state changes in your test suite by using a pool of disposable containers.

A Graybeard's Worst Nightmare - How Docker Containers are Re-Defining the Linux OS

Feedback Survey

OCI (aka Docker) containers are having a deep impact on the Linux operating system (OS) that goes well beyond DevOps and "cloud native" applications. The concepts of application-centric packaging, process isolation through Linux containers, and immutable infrastructure are shaking up the core traditions of today's GNU/Linux operating systems. These concepts are also challenging the assumptions and approaches derived from the past forty-plus years of work that originated with UNIX. The Linux distribution as we know it is coming to an end, and is being replaced by a new concept of containerized, multi-instance, multi-user applications, which can be deployed in scale-out environments. This presentation provides an assessment and outlook on this new OS environment and takes a deep look at the consequences that this new OS model has for both developers and operators.

Docker for Java EE developers

Feedback Survey

Containers are enabling developers to package their applications in new ways that are portable and work consistently everywhere! On your machine, in production, in your data center, and in the cloud. And Docker has become the de facto standard for those portable containers in the cloud. This lab offers developers an intro-level, hands-on session with Docker, from installation, to exploring Docker Hub, to crafting their own images, to adding Java apps and running custom containers. This is a BYOL (bring your own laptop) session, so bring your Windows, OSX, or Linux laptop and be ready to dig into a tool that promises to be at the forefront of our industry for some time to come.

Atomic, with and without Atomic

Feedback Survey

On Atomic Host, yum is not used to install software. Anything which is not in the base image needs to be deployed as container. That includes not just web applications or databases but system tools and daemons as well.

When we have such container / image, it is possible to deploy it on non-Atomic installation as well, taking advantage of the atomic command which simplifies the installation and configuration using metadata from the image. It is even possible to go back and forth between containerized and non-containerized daemon.

We will share our experience preparing SSSD for Atomic Host and how it can be tested and used in non-Atomic environment.

Demo will be part of the session
