Vagrant – another tool from Hashicorp – provides easy to configure, easily reproducible and portable work environments that are built on top of industry standard technology. Vagrant helps enforce a single consistent workflow to maximise the flexibility of you and your team. The learning curve is quite high for those who are unfamiliar with puppet, and the ruby DSL may seem unfamiliar for users who have no development experience. The Code First Girls +Masters is a four-week intensive course that will provide learners with additional skills and knowledge across DevOps & Cloud, Mobile App Development or Analysis & Product Management.

Gradle is an open source build automation tool that builds upon the concepts of Apache Ant and Apache Maven and introduces a Groovy-based DSL instead of the XML form used by Maven. Its terminology can seem a little arcane and new to novices. Revert, for instance, has a very different meaning in Git than it does in SCM and CVS. However, it rewards that investment curve with increased development speed once mastered. Collectd helps you collect and visualise data about your servers, and thus make informed decisions. It’s useful for working with tools likeGraphite, which can render the data that collectd collects. Consul is a tool for discovering and configuring services in your infrastructure.


DevOps is a set of practices that combines software development and IT operations. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality. DevOps is complementary to Agile software development; several DevOps aspects came from the Agile methodology. Over time, we’ve built a workflow that helps our engineers ship product faster than ever before. I’ve got my DevOps hat on today and so I would like to share with you the evolution of our continuous integration pipeline and the little quick wins you can make in terms of speed and cost. Containers are amazingly useful development tools, but their biggest long-term impact may be as a platform for running applications in production. Achieving this will require advancements in container operations, infrastructure and orchestration.

Docker for DevOps Lessons

Moving your application into a container and deploying it to production is a great first step towards taking advantage of containerization. This gets you past “works on my machine”, and Docker makes this easy. But the real value of containers — fast immutable deployments, maximizing resource utilization, and bare-metal performance — comes from an architecture optimized for containers. Rarely, however, is there a technology that enables the practice of DevOps. The advent of the cloud and disposable infrastructure is one example.


You could install Git, 72Zip, Ruby, or even Microsoft Office! The catalogue is now incredibly complete – you really can install a wide array of apps using Chocolatey. The main downside of AWS is that all of your servers are virtual.

If you make changes, you can send a notification called a “pull request” to the original owner. The user can then merge your changes with the original repo. CoreOS gives you a stack of systemd, etcd, Fleet, Docker and rkt with very little else. It’s useful for spinning up a large cluster where everything is going to run in Docker containers. Security Monkey– searches out security weaknesses, and ends the offending instances. It also ensures that SSL and DRM certificates are not expired or close to expiration. Latency Monkey– simulates a degradation of service and checks to make sure that upstream services react appropriately.

Cisco Professional Services

This basically means that every job execution is isolated in a container. You can check out the pros and cons between the executor typeshere. Checkpoint/Restore is a technology that makes it possible to take snapshots of running Linux processes and restore them at any other place and time. This opens up exciting possibilities including live migration, keeping HPC tasks safe from hardware problems, cloud services and dynamic load balancing. Containers are great for the stateless applications, but what about applications that rely on persistance of data? Ryan will talk about how to handle storage for your containers and. Why running stateful services in containers can make a lot of sense.

Ansible and Puppet for Large Infrastructures

Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. The Jump is based in London, UK, but Docker for DevOps Lessons all our training is delivered remotely so that our students can learn to become software engineers, from anywhere. We will start by defining how Docker influences the DevOps process. We will then design and build simple containers, with a clear outline of how applications are involved in the process. Then we will define the key highlights when setting up multiple containers while setting up a number using docker-compose, Docker’s tool for running multi-container applications.
