Общ преглед

Docker is an open-source platform for building, shipping and running applications inside containers. Kubernetes goes one step further by providing the tools needed to deploy and manage containerized applications at scale in a clustered environment.

In this instructor-led, live training (onsite or remote), participants will learn how to deploy a collection of sample servers inside containers, then automate, scale, and manage their containerized servers within a Kubernetes cluster. The training goes on to more advanced topics, walking participants through the process of securing, networking and monitoring a Kubernetes cluster.

By the end of this training, participants will be able to:

Set up and run a Docker container.
Deploy containerized databases and servers.
Set up a Docker and Kubernetes cluster.
Use Kubernetes to deploy and manage different environments under the same cluster.
Secure, scale and monitor a Kubernetes cluster.

Format of the course

Part lecture, part discussion, exercises and heavy hands-on practice.

Notes

Different Docker images can be used as demos in this training (e.g., Nginx, MongoDB, Tomcat, etc.).

Chris Stent - Volkswagen Financial Services U.K.

Excellent knowledge and experience of Kubernetes and how to get the best out of it and to work with Docker. For me personally, although Docker experience was a pre-requisite, I found that Kamil really helped me embed that knowledge with real examples.

Lakshmi is such a kind person and an absolute professional. I really learned useful information about Docker and Kubernetes!

Lucian Gheorghe - eMAG IT Research SRL

The course is very well structured. It also has exercises and examples for everything that is presented.

Marius Ilina - eMAG IT Research SRL

The fact that he took the time to explain everything in great detail

eMAG IT Research SRL

I like >workshop< approach, that we learned something in theory and moved to example done together and then alone. I really liked common exercises when one person was sharing the screen and rest of the group was trying to help, to do the exercise. But sometimes not everything was clear enough, like something was missing in configuration and we were expected to point it out. From my point of view it would be nice to know in advance that something is missing and we should find solution for such problem, because in such cases, I wasn't sure if something is wrong only in my config, should I search the internet for solutions or what.

The subjects were modified based on our knowledge. People with less knowledge and people with more knowledge equally learned something.
