Security, too, is handled through the interface. Much like Docker Datacenter which is also an official Docker product , Docker Cloud offers a GUI, browser-based console for managing all aspects of your Docker deployments. This includes administration for your host nodes running in public clouds.

The big difference is that, unlike Datacenter, the Docker Cloud administration service is hosted from the cloud. Docker Cloud organizes resources into node clusters, which are groups of individual nodes being managed as part of a single service, all dedicated to a unified deployment goal. I think that part of the reason Docker continues to promote two such similar services Datacenter and Cloud goes a couple of years back to when Docker purchased a company called Tutum and renamed their web-based product Docker Cloud.
Tutum already had a happy customer base and a fairly successful business model, so there was no reason to shut it down. In any case, both work, so just pick whichever one rings your bell. To be honest, figuring out how all the many ECS pieces fit together can be a tough task. Elastic Beanstalk effectively sits on top of ECS, allowing you to deploy your application across all the AWS resources normally used by ECS, but with virtually all of the logistics neatly abstracted away.
Effectively, all you need in order to launch a fully scalable, complex microservices environment is a declarative JSON-formatted script in a file called Dockerrun. You can either upload your script to the GUI or, from an initialized local directory using the AWS Beanstalk command line interface, run it using:. I should mention that Dockerrun. The idea is that you can designate one of your servers known as a node as a manager:.
And to say that Kubernetes is popular is like saying rain is wet. Kubernetes organizes resources into pods, which themselves are made up of interconnected containers running individual microservices. You should think of a pod as being entirely disposable, its function instantly replaceable by others awaiting their chance to enter this world. In fact, pods are created and destroyed according to the needs defined on the Master node by things like schedulers and replication controllers, all of which can, in turn, be managed by the kubectl program. Pods - and their containers - run on servers known as worker nodes running their own instances of Docker Engine.
How to choose the right container orchestration and how to deploy it

David Clinton Oct Beating the technology learning curve monster. The whole idea of Docker is for developers to easily develop applications, ship them into containers which can then be deployed anywhere. In this course students will get the foundational concepts and practices of containerization on a single Docker node, then learn the foundations of orchestration and scale out with Docker across multiple nodes in a swarm and this course is a prerequisite for all other Docker courses. Docker fundamentals includes concepts and configurations like how to create Dockerfiles, build, manage and distribute Docker images and configure Containers.
By the time you finish this course you'll know everything you need to start using Docker on your own applications. The Docker Fundamentals training course features the foundational concepts and practices of containerization on a single Docker node. The course offers students the opportunity to assimilate basic container orchestration and how to scale Docker across multiple nodes in a simple swarm cluster.
This course provides essential foundational knowledge for subsequent Docker courses. Understand and managing Docker Container Volumes Gain a thorough knowledge about the networking in Docker Understanding and working with Docker Compose Deploying multi-layered Applications Understand how Swarm works and Deploy a swarm application. Dockers Advanced Administration In this course you will see Docker under the hood and discover in depth knowledge which helps the developers to become more confident and efficient.
This course will also help students to learn how to deploy, setup UCP and manage DTP by creating public and private repositories. By this course completion, students will be able to deploy Docker engine on Linux and Windows environments and perform advanced Docker functions.
How to choose the right container orchestration and how to deploy it
Perform basic monitoring, logging, and health checks to the cluster. Kubernetes Administration Containers are not a new thing, but implementing them was always a little more complicated than it needed to be. Docker made great leaps in simplification of container. Docker makes it possible to get far more apps running on the same old servers and it also makes it very easy to package and ship programs. Docker is a transcendent tool for those who transfer, install, and manage software applications on a regular basis.
The advent of Kubernetes, however, has somehow made containerizing and automating applications even easier. Kubernetes is an open source orchestration system for container based distributed applications. Originally created by Google based on principles from its internal orchestration system, Kubernetes is now developed on GitHub, it provides several level of fault-tolerance, scalability and useful primitives that go beyond the single container concept.

In this course students will get an understanding of Docker and its concepts, and become a master of automating deployment, scaling, and management of containerized applications using Kubernetes. The course will explain you how to setup your cluster on your desktop, or on the cloud using AWS, Kubernetes desktop installation.

You will also learn how to build apps in containers using docker and how to deploy those on a Kubernetes cluster using native OS tools such as Ubuntu, set up a cluster, and create container registry. The course will also help you learn components in the Kubernetes architecture and useful commands for deploying and managing a cluster.
OpenShift Enterprise by Red Hat, Red Hat's platform-as-a-service PaaS offering, provides pre-defined deployment environments for applications of all types through its use of container technology.

This enables an environment that supports DevOps principles such as reduced time to market and continuous delivery. This course is part of a series of DevOps courses that center around the use of OSE to enable continuous delivery a key goal in the DevOps philosophy.
At the end of this course, you will be able to: Describe the features and architecture of the Red Hat OpenShift Enterprise product Install Red Hat OpenShift Enterprise and configure a master and node Execute commands using the command line interface Create, build, and deploy applications to a OpenShift Enterprise instance Use OpenShift components to manage deployed applications Customize resources and processes used by OpenShift Enterprise.
Jenkins Fundamentals Jenkins is the de facto standard for continuous integration server. Jenkins plays a vital role in DevOps tool chain through automating the flow in DevOps continuous delivery process. Jenkins has the largest plugins community, covering almost all popular tools and is the leading open source automation server providing hundreds of plugins to support building, deploying and automating any project. Gain the expertise to implement a continuous build environment with Jenkins. Learn to effectively set up production-grade instances of a Jenkins server, complete with automated builds, tests, code quality audits and reports.
In this course you will learn everything you need to know to get started on Jenkins and setup your first continuous integration server.
