Docker Training Course

About

Docker has been acclaimed as a revolution for the IT world. This open source project is already making a lot of changes on how developers and system administrators setup new server and web environments. If you never heard about Docker, I’ll try to explain it in a couple of lines with Wikipedia’s help:

Docker is an open-source project that automates the deployment of applications inside software containers, providing that way an additional layer of abstraction and automatization of operating system–level virtualization on Linux.Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent “containers” to run within a single Linux instance, avoiding the overhead of starting virtual machines.

We have two courses on Docker...
Docker Fundamentals
Number of Day - 1
This course covers the foundations of the Docker platform, including an overview of the platform components, images, containers and repositories.

Docker Advance and Operations 
Number of Day - 2
This also course covers topics to help you operate a Dockerized application environment. From understanding Docker Orchestration with Machine, Swarm and Compose, to security best practices and troubleshooting Docker containers. Private repository and registry concepts are also explained in this course. This two day course is designed to help new and experienced systems administrators learn to use Docker to control the Docker daemon, security, Docker Machine, Swarm, and Compose.
