Kubernetes-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.

Kubernetes is a tool born in the laboratories of Google, which donated it to the CNCF (Cloud Native Computing Foundation) a few years ago. Designed by Google to enable the deployment of their applications in their data centers scattered around the world, Kubernetes is today the major infrastructure software in the implementation of a large number of distributed applications.

Having become the de facto standard for large-scale deployment of containerized applications, this course addresses the structuring elements of the tool, the understanding and mastery of which will allow you to operate applications that require high elasticity.

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

• Basic Linux commands
• Knowledge of Docker (containers, images, Dockerfile)
• 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.
