Docker Containers

In the course Docker Containers participants learn how to use Docker containers in application development.

Docker Intro

The course Docker Containers starts with an explanation of how Docker containers work. The participants learn to create and run Docker containers. Unlike virtual machines, Docker uses resource isolation so that several independent containers can run in an operating system instance. The containers can be created, started, and stopped just like processes.

Docker Commands

The various Docker commands such as run, pull, push, build and search are covered. Attention is also paid to hosting Docker containers, such as hosting in the registry or hosting in web applications

Docker Images

Next attention is paid to Docker Images, in which the difference between Base and Child images is discussed, among other things. A Docker image is a runtime environment and the image is created with the instructions in a Dockerfile. The content of a Docker file is also explained.

Cloud Deployment

Cloud Deployment on various cloud platforms such as AWS, Azure and Google App Engine is also on the program of the course Docker Containers. Docker machines are local or remote computers with an IP address on which the Docker service runs. Typically these are also present in cloud environments such as AWS, Amazon Web Services.

Multi Container Environments

Finally attention is paid to the use of Docker containers in a Microservices Architecture, the use of multiple containers side by side and in a cluster in combination with the Kubernetes cluster orchestration system.

Audience Course Docker Containers

The course Docker Containers is intended for developers who want to use Docker containers for application development.

Prerequisites Course Docker Containers

To participate in the course Docker Containers the participants should have experience with the development of applications and related matters.

Realization Training Docker Containers

The theory is explained on the basis of presentations. The concepts are illustrated with demos. The theory is interspersed with exercises. The course times are from 9.30 to 16.30.
