Swarm in a nutshell
• Exposes several Docker Engines as a single virtual Engine
• Serves the standard Docker API
• Extremely easy to get started
• Batteries included but swappable
At DockerCon EU we introduced Docker Swarm: a Docker-native clustering system. It allows you to connect to a single Docker endpoint and run containers on an entire cluster.
Docker Swarm comes with a simple discovery service, for an easy setup. If you already have a discover service within your infrastructure like consul or etcd, you can use those instead.

The age of orchestration: from Docker basics to cluster managementNicola Paolucci
The container abstraction hit the collective developer mind with great force and created a space of innovation for the distribution, configuration and deployment of cloud based applications. Now that this new model has established itself work is moving towards orchestration and coordination of loosely coupled network services. There is an explosion of tools in this arena at different degrees of stability but the momentum is huge.
On the above premise this session we'll delve into a selection of the following topics:
- Two minute Docker intro refresher
- Overview of the orchestration landscape (Kubernetes, Mesos, Helios and Docker tools)
- Introduction to Docker own ecosystem orchestration tools (machine, swarm and compose)
- Live demo of cluster management using a sample application.
A basic understanding of Docker is suggested to fully enjoy the talk.
Docker 1.12 is on everyone's lips these day. With built in Swarm mode, we can achieve orchestration out of the box with simplicity, reliability, and effective scalability. I had the pleasure of presenting Docker 1.12 and Swarm at a DevOps meetup held at SA Home Loans.

Infrastructure Deployment with Docker & AnsibleRobert Reiz
This is an introduction to Docker & Ansible. It shows how Ansible can be used as orchestration too for Docker. There are 2 real world examples included with code examples in a Gist.
Title: Ansible, best practices.
Ansible has taken a prominent place in the configmanagement world. By now many people involved in DevOps have taken a look at it, or done a first project with it. Now it is time to step back and look at quality and craftmanship. Bas Meijer, Ansible ambassador, will talk about Ansible best practices, and will show tips, tricks and examples based on several projects.
About the speaker
Bas is a systems engineer and software developer and wasted decades on latenight hacking. He is currently helping out 2 enterprises with continuous delivery and devops.
My talk from the Mountain View Docker Meetup on Feb 24, 2016. It covers what Docker Swarm is, how to create a cluster, and then walks you through a sample app. Embedded links point to the public Github repo containing the sample app, as well as a series of Youtube videos showing how to reproduce the demo on your own.

www.nitim.eu is Ph.D. network on Network, Information Technology and Innovation Management
Objectives: reflecting upon which incentives social marketing and health education are based on, and their differences
and interconnections becomes essential to promote healthy lifestyles and ensure a free and sustainable future.
Methods: in order to promote health, it is necessary to use all the incentives that contribute to achieving this end.Health education, social marketing and laws (expression of the policy) are to be considered the functional medium
of health promotion to be used generally or individually, according to the targets/contexts.
Results: the methods used to promote health are work in progress, the Community Based Prevention Marketing is
such an expression.
Conclusions: considering health as a resource for everyday life means externalizing it from what is seen as the sole
responsibility of the health system. Health should become the purpose of actions which, through cross-sector
synergies, concern the different components of civil society, particularly political agendas.
Introducing Docker Swarm - the orchestration tool by DockerRamit Surana
Swarm is native clustering for Docker containers. It pools together several Docker Engines into a single, virtual host. Point a Docker client or third party tool (e.g., Compose, Dokku, Shipyard, Jenkins, the Docker client, etc.) at Swarm and it will transparently scale to multiple hosts.
In addition to authorization policies that control what a user can do, OpenShift Container Platform gives its administrators the ability to manage a set of security context constraints (SCCs) for limiting pods and securing their cluster.
Default security context may be too restrictive for containers pulled down from DockerHub, thorugh this talk we'll explore the various steps to execute for enabling required permissions on selected OpenShift's pods.
A guide to deploying an initial Docker Swarm mode network and then incorporating Asterisk into that swarm. Commands, a discussion of host mode vs overlay networking, and the basics of a deployable Docker Swarm mode Stack file are all covered.
Overview of Docker 1.11 features(Covers Docker release summary till 1.11, runc/containerd, dns load balancing ipv6 service discovery, labels, macvlan/ipvlan)
Since its first 1.12 release on July 2016, Docker Swarm Mode has matured enough as a clustering and scheduling tool for IT administrators and developers who can easily establish and manage a cluster of Docker nodes as a single virtual system. Swarm mode integrates the orchestration capabilities of Docker Swarm into Docker Engine itself and help administrators and developers with the ability to add or subtract container iterations as computing demands change. With sophisticated but easy to implement features like built-in Service Discovery, Routing Mesh, Secrets, declarative service model, scaling of the services, desired state reconciliation, scheduling, filters, multi-host networking model, Load-Balancing, rolling updates etc. Docker 17.06 is all set for production-ready product today. Join me webinar organised by Docker Izmir, to get familiar with the current Swarm Mode capabilities & functionalities across the heterogeneous environments.
Get hands-on with security features and best practices to protect your containerized services. Learn to push and verify signed images with Docker Content Trust, and collaborate with delegation roles. Intermediate to advanced level Docker experience recommended, participants will be building and pushing with Docker during the workshop.

What is Docker and why should you care? A Docker container is like a
lightweight Virtual Machine. It gives you the benefits of a virtual machine,
isolation of your application, without the drawbacks, having to ship an entire
operating system with your application, slow startup time, and difficult
interaction with the host.
In this presentation you will learn why Docker and containerization is the
future of DevOps and how to use it efficiently. You will learn how to build,
run, and link containers, and what volumes are and what they are used for.
You will also learn about some of the many orchestration solutions that exists
for managing a cluster of containers, both locally and in the cloud.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.
