Kubernetes is the gold standard in the world of container orchestration. It was originally created by Google, based on their experience of building and managing containers at scale ( at Google Scale). However its now driven by Cloud Native Compute Foundation ( CNCF), an open body, which also offers the official certification i.e. "Kubernetes Certified Administrator". Kubernetes comes with mind boggling features, is very reliable, and extremely sophisticated container orchestration engine. It can let you convert your infrastructure into a Container as a Service (Platform), brining in some of the awe inspiring features such as Zero Down Time Deployments, Fault Tolerance, Auto Scaling, Cloud and Storage integrations, which were extremely difficult to implement. And it brings it to the masses with its truly open, lock in free eco system.

Jupyter x Docker

Deploy a Jupyter Notebook Server using Docker Containers on Heroku.

"]

Students: 6462, Price: Free

Learn to create a Python Jupyter Notebook Server with Docker & Heroku. This series builds gives you a step-by-step reference to deploy an interactive notebook to allow your projects to be more literal while making it easier for non-technicals to run your code.

Jupyter is a tool for running interactive notebooks; basically add Python with Markdown and you've got Jupyter. if you haven't used it before, I recommend you do.

Docker is a tool that gives us control over our application's OS environment. Think of it like a recipe for your OS that you can share almost anywhere. In this one, we'll be covering deploying this project to Heroku but using Docker means we can deploy this nearly anywhere.

In this series, I'm going to show you how to deploy a Jupyter Notebook server on Heroku using Docker step-by-step.

The big caveat

Jupyter has the ability to create new notebooks and they will 100% save on your deployed docker-based Jupyter server... but they will disappear as soon as you deploy a new version. That's because containers, by their very nature, are ephemeral by default.

This caveat doesn't mean we shouldn't do this... it just means it is a HUGE consideration when using this guide over something like Google Colab.

  • Scalability

  • Load Balancing

  • Service Discovery

  • High Availability

  • Auto replication

  • Auto restart

  • Security and much more.

But there are some differences as well which make us confused to choose between them. Docker, Docker Swarm, and Kubernetes are tools that make life easier for technology professionals. To make use of these amazing resources, you need to understand their relative strengths and capabilities. In this course, you'll learn all the fundamental concepts, strength, capabilities, difference and much more with lots of  hands on practical implementation of Kubernetes and Docker Swarm.

Both of them are powerful and popular now it's your choice to choose them according to the requirement.

Containers are everywhere and making developer's life easy that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.

In this course, you are going to learn about Docker, the containerization platform, and Kubernetes, the container orchestration platform.

Docker is an open source platform for building, deploying, and managing containerized applications in mission to solve the 'it works on my machine' headache. Kubernetes, also known as K8s, is an open-source container orchestration tool for automating deployment, scaling, and management of containerized applications.

In this learning path, you'll learn all the fundamental concepts of Docker and Kubernetes in pragmatic style. First and foremost you'll learn how to use docker image and then how to build custom docker image for any application using Dockerfile. Then you'll explore and practice all important commands as important skills to quality for the DCA certification.

After it you'll learn how to push docker image into docker hub and Docker compose to manage multiple containers.

Docker Compose runs on a single host, whereas Kubernetes typically uses multiple nodes, which can be added or removed dynamically. So you'll also learn how to manage containers using Kubernetes and how to make application scalable and fault tolerant.

You'll have lots and lots of detailed hands on various commands and writing YAML.

Docker and Kubernetes are the crucial skill set for anyone who wants to start a new career or switch to new company.

This course is fully based on pragmatic approach without any kind of bogus content. A short, precise and practical oriented course for IT pros just like you.

In this learning track, you are going to learn about popular container orchestration tool, Openshift.

So what is Openshift?

Containerization enables companies to become more agile and scalable. Docker enables you to pack your code with required dependencies/lib to make your application to run anywhere. To manage docker containers or any container orchestration tool is used. Openshift is one of them.

Openshift is Kubernetes with some additional addons which makes Openshift more then K8s. It removes the complexity of Kubernetes into sorted manner.

To make you more confident with Openshift, this course is design in such a manner that will help you to build strong foundation and practically fit to deploy applications into it.

This tutorial covers topics like

  • Building single node cluster with Minishift

  • Creating multi cluster environment

  • Creating YAML file to deploy Pod, Replication Controller, Replica Set, Deployment, Deployment Config, ImageStream, Configmap, secrets and much more

  • Using Openshift web console to manage Pod, Replication Controller, Replica Set, Deployment Config, Deployment and much more.

  • Scaling the application according to workload

  • Creating high availability(HA) and auto scaling applications

  • Creating projects and managing users

  • Accessing containers running inside pod

  • Debugging and monitoring running objects

  • Understanding all the commands of oc and Minishift

  • Using catalogue to build applications and much more.

Lectures backed by practical exercises makes it easy to understand without wasting time in doing troubleshooting. This is the only course that provides 90% practical hands on with 10% theory to support the topic.

Beyond Jupyter Notebooks

Build your own Data science platform with Docker & Python

Interactive notebooks like Jupyter have become more and more popular in the recent past and build the core of many data scientist’s workplace. Being accessed via web browser they allow scientists to easily structure their work by combining code and documentation. Yet notebooks often lead to isolated and disposable analysis artefacts. Keeping the computation inside those notebooks does not allow for convenient concurrent model training, model exposure or scheduled model retraining.

Those issues can be addressed by taking advantage of recent developments in the discipline of software engineering. Over the past years containerization became the technology of choice for crafting and deploying applications. Building a data science platform that allows for easy access (via notebooks), flexibility and reproducibility (via containerization) combines the best of both worlds and addresses Data Scientist’s hidden needs.
