Training details

Description

This training is designed for developers who want to create or tune applications using Docker, for optimal integration into the Kubernetes ecosystem. You will gain a deep understanding of how the Docker daemon works and the main commands. You will explore the various Kubernetes resources needed to deploy applications. Through practical exercises, you will master how to package your applications in Docker containers before publishing them in a private registry. You'll learn how to deploy them in a Kubernetes environment, while following the 12-factor application patterns, to fully exploit the power of the orchestrator. Finally, you will be guided in learning how to monitor your applications and manage their complete lifecycle.

Objectives

• Building a Docker image
• Publishing a Docker image to a repository
• Managing a Docker Container
• Tuning an application for the Kubernetes environment
• Setting up an application deployment in Kubernetes
• Application monitoring
• Exploring advanced Kubernetes features

Target Audience

• Developer
• Architect

Prerequisites

Laptop with at least 8Gb of memory, IDE & linux installed whith basic practice of software programming. Strong understanding of the Linux ecosystem and web applications. During the training, you can use the programming language that you usually use.

Pedagogical method

Learning by doing. Practical training, aimed at acquiring know-how, based on a practical case as well as exchanges and feedback from the trainer's practical experience. An Event Storming session will be offered to participants to appropriate the business problems, and follow an implementation (in pairs or all together).

• Proportion of presentations: 60%
• Proportion of practical cases: 30%
• Proportion of experience sharing: 10%

Evaluation and follow-up mode

The evaluation of the acquired skills takes place throughout the session through workshops and practical implementations. A hot evaluation of the satisfaction of the trainees is systematically carried out at the end of the session and a training certificate is issued to the participants mentioning the objectives of the training, the nature, the program and the duration of the training action as well as the formalization of the acquired skills.
