Docker-en

• La formation se compose de travaux pratiques (mises en situation, débats, exercices).
• Une évaluation quotidienne de l'acquisition des connaissances de la veille est effectuée.
• Une synthèse est proposée en fin de formation.
• Une évaluation à chaud sera proposée au stagiaire à la fin du cours.
• Un support de cours (version électronique) sera remis à chaque participant comprenant les slides sur la théorie, les exercices.
• Une feuille d'émargement par demi-journée de présence est fournie en fin de formation ainsi qu'une attestation de fin de formation si le stagiaire a bien assisté à la totalité de la session.

Containerization is becoming a must-have in modern computing. Docker is one of the most widespread implementations, simplifying its use.

Docker is first used by developers to speed up the implementation of their development environment and obtain an easier installation of different servers or databases. Then, it became a major element in modern IT infrastructures. Ubiquitous, it is revolutionizing the way we think about today's IT activities: setting up CI/CD pipelines, deploying infrastructures on runtime platforms (Kubernetes).

Objectives

Understanding the Principle of Containerization

Know how to install and use Docker

Build Docker images with a Dockerfile

Leverage different registries: Docker Hub or private registries

Outsource container data with volumes

Setting up the network layer of a container with networks

Orchestrate your containers with docker-compose

Docker and runtimes: Kubernetes, Docker Swarm

• Understand the principle of containerization
• Build Docker images with a Dockerfile
• Use Docker registries (Docker Hub, private registries)
• Manage data persistence with volumes
• Configure container networking

Le formateur est un expert du domaine qui intervient sur le sujet depuis plusieurs années en formation mais aussi en conseil.

• Basic Linux commands
• In order to validate the skills and prerequisites of each participant, prior to the training, the trainer organizes a phone interview. He then confirms that the participant has the required level and that the content meets their expectations.
