The age of orchestration: from Docker basics to cluster management
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 Machine & Docker Swarm
This document provides an agenda and overview of Docker Machine and Docker Swarm. It discusses how Docker Machine allows managing Docker hosts on various platforms and distributions. It then explains how Docker Swarm exposes multiple Docker engines as a single virtual engine with built-in service discovery and scheduling. The document demonstrates how to set up a Docker Swarm cluster using the hosted discovery service and covers Swarm scheduling strategies, constraints, and container affinities.
Docker swarm introduction
Docker Swarm allows managing multiple Docker hosts as a single virtual Docker engine. The presenter demonstrates setting up a traditional Docker Swarm cluster with an external key-value store and load balancer. SwarmKit provides the core components of Docker Swarm as standalone binaries. Docker Swarm Mode is integrated directly into Docker Engine 1.12 and later, providing built-in orchestration without external components. The presenter then demonstrates a tutorial using Docker Swarm Mode to deploy a multi-container voting application across 3 Docker hosts and scale the service.
Docker Swarm Introduction
Docker Swarm allows managing Docker clusters remotely. The key components are swarm managers, swarm nodes, and a scheduler. Swarm managers oversee nodes in the cluster using Docker APIs. The scheduler uses strategies and filters to determine where to place containers on nodes. Discovery services help register and discover nodes in the cluster.

Docker Online Meetup #28: Production-Ready Docker Swarm
presented by Alexandre Beslic (@abronan)
Swarm v1.0 is now ready for running your apps in production!
Swarm is the easiest way to run Docker applications at large scale on a cluster. It turns a pool of Docker Engines into a single, virtual Engine. You don’t have to worry about where to put containers, or how they’re going to talk to each other - it just handles all that for you.
We’ve spent the last few months tirelessly hardening and tuning it, and in combination with multi-host networking and the new volume system in Docker Engine 1.9, we can confidently say that it’s ready for running your apps in production. In our tests, we’ve been running Swarm on EC2 with 1,000 nodes and 30,000 containers and it keeps on scheduling containers in less than half a second. Not even breaking a sweat! Keep an eye for a blog post soon with the full details.

Commands like "docker ps" are available in-game. The mod aims to simplify container management and visualization, as well as teach Docker concepts to young players. It's open source on GitHub where the creator welcomes feedback to improve the project.
Swarm - A Docker Clustering System
This document discusses Docker Swarm, a native clustering service for Docker that allows scheduling of container workloads across multiple hosts. It describes how to set up a Swarm cluster by labeling multiple machines and joining them to a Swarm manager node. The Swarm manager then uses scheduling options like filters and strategies to distribute containers across hosts based on constraints, affinity, ports, dependencies, health checks, and node labels. While the Swarm API is mostly compatible with Docker's API, it currently has some missing endpoints and differences related to TLS support for secure communication in the cluster.
Introduction to docker and docker compose
Docker allows packaging applications and dependencies into virtual containers that can run on any Linux server. This provides flexibility and portability. Docker images are lighter than virtual machines and use less storage. Docker Compose is a tool that defines and runs multi-container Docker applications using a YAML file to automate building, running, and linking containers together. It handles dependencies and startup order of containers to simplify running complex applications with multiple services.
Docker Container As A Service - March 2016
This document discusses Docker Containers as a Service (CaaS). It begins by showing how Docker can be used to build a software layer on top of the internet hardware layer. It then discusses how Docker can be used with different cloud platforms and orchestration tools. It presents Docker CaaS as addressing the needs of both developers and IT operations by supporting the full application lifecycle across any infrastructure or operating system. Key characteristics of Docker CaaS include open APIs, pluggable architecture, and broad ecosystem support.

Load Balancing Apps in Docker Swarm with NGINX
On-demand webinar recording: http://bit.ly/2mRjk2g
Docker and other container technologies continue to gain in popularity. We recently surveyed the broad community of NGINX and NGINX Plus users and found that two-thirds of organizations are either investigating containers, using them in development, or using them in production. Why? Because abstracting your applications from the underlying infrastructure makes developing, distributing, and running software simpler, faster, and more robust than ever before.
But when you move from running your app in a development environment to deploying containers in production, you face new challenges – such as how to effectively run and scale an application across multiple hosts with the performance and uptime that your customers demand.
The latest Docker release, 1.12, supports multihost container orchestration, which simplifies deployment and management of containers across a cluster of Docker hosts. In a complex environment like this, load balancing plays an essential part in delivering your container-based application with reliability and high performance.
Join us in this webinar to learn:
* The basic built-in load balancing options available in Docker Swarm Mode
* The pros and cons of moving to an advanced load balancer like NGINX
* How to integrate NGINX and NGINX Plus with Swarm Mode to provide an advanced load-balancing solution for a cluster with orchestration
* How to scale your Docker-based application with Swarm Mode and NGINX Plus

Java Garbage Collectors – Moving to Java7 Garbage First (G1) Collector
One of the key strengths of JVM is automatic memory management (Garbage Collection). Its understanding can help in writing better applications. This becomes all the more important as enterprise server applications have large amount of live heap data and significant parallel threads. Until recently, main collectors were parallel collector and concurrent-mark-sweep (CMS) collector. This presentation introduces the various Garbage Collectors and compares the CMS collector against its replacement, a new implementation in Java7 i.e. G1. It is characterized by a single contiguous heap which is split into same-sized regions. In fact if your application is still running on the 1.5 or 1.6 JVM, a compelling argument to upgrade to Java 7 is to leverage G1.

Plumbing tips
This document provides several tips for common plumbing issues:
1) Use pipe insulation to prevent sprayer hoses from catching on shutoff valves.
2) Use a shop vacuum to remove hard objects like toys that are clogging drains, rather than using a plunger which may push them deeper.
3) Wrap pipes in adhesive-backed felt to reduce noise from expanding pipes rubbing against hangers.

How to build a Distributed Serverless Polyglot Microservices IoT Platform us...
When people aren't talking about VMs and containers, they're talking about serverless architecture. Serverless is about no maintenance. It means you are not worried about low-level infrastructural and operational details. An event-driven serverless platform is a great use case for IoT.
In this session at @ThingsExpo, Animesh Singh, an STSM and Lead for IBM Cloud Platform and Infrastructure, detailed how to build a distributed serverless, polyglot, microservices framework using open source technologies like:
OpenWhisk: Open source distributed compute service to execute application logic in response to events
Docker: To run event driven actions 6. Ansible and BOSH: to deploy the serverless platform
MQTT: Messaging protocol for IoT
Node-RED: Tool to wire IoT together
Consul: Tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.
Kafka: A high-throughput distributed messaging system.
StatsD/ELK/Graphite: For statistics, monitoring and logging

Docker swarm-mike-goelzer-mv-meetup-45min-workshop 02242016 (1)
Swarm allows multiple Docker hosts to be clustered together into a single virtual Docker host. The document discusses how to set up a Swarm cluster in three steps: 1) Create a key-value store, 2) Run the Swarm manager container, and 3) Configure Docker daemon arguments on hosts. It also provides an example of running a microservices voting application on Swarm and references additional example repositories.
Docker
Docker provides tools for building and running containerized applications. The Docker Engine manages Docker objects like images, containers, networks and volumes. Docker Desktop is for Mac/Windows and includes Docker Engine and other tools. Docker Compose defines multi-container apps. Docker Hub is a public registry and Docker Swarm manages clusters of Docker Engines.
Orchestration of docker containers at scale
The document discusses orchestrating docker containers at scale using docker swarm. It begins with an introduction to docker and containers versus VMs. It then covers clustering docker containers using swarm, including creating a swarm master, joining nodes, and using the docker remote API. Finally, it briefly demonstrates these concepts.
Building Bizweb Microservices with Docker
This document discusses using Docker to build and deploy microservices for a Bizweb application. It proposes using Docker Swarm mode for orchestration along with Netflix OSS components like Eureka, Zuul and Ribbon to provide service discovery, API gateway functionality and load balancing between microservices. Continuous integration is achieved using Jenkins to build Docker images from code commits, tag them and push to a private Docker registry. When code is committed, Jenkins triggers deployment of updated services to a Docker Swarm cluster for testing or production. This approach aims to reduce delivery time, simplify deployment and scaling of microservices.

This document discusses using Docker for testing by simplifying Selenium grid and containerizing tests. Docker allows running multiple browser versions and OSes easily for automation testing. Selenium grid is simplified using Docker images for the hub and nodes, eliminating the need for VMs. Tests are containerized using a Dockerfile to build a test image that can access the application using Docker networking and volumes. Docker compose is used to define and scale the grid and test containers.
What's New in Docker 1.12?
Docker Engine 1.12 can be rightly called ” A Next Generation Docker Clustering & Distributed System”. Though Docker Engine 1.12 Final Release is around corner but the recent RC3 brings lots of improvements and exciting features. One of the major highlight of this release is Docker Swarm Mode which provides powerful yet optional ability to create coordinated groups of decentralized Docker Engines. Swarm Mode combines your engine in swarms of any scale. It’s self-organizing and self-healing. It enables infrastructure-agnostic topology.The newer version democratizes orchestration with out-of-box capabilities for multi-container on multi-host app deployments.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
