- Understanding the concept of containerization, grasping its essence, problem-solving nature, and differentiation from virtual machines.
- Application of Docker as a containerization tool and awareness of alternatives like Podman.
- Familiarity with Docker's configuration elements (such as storage and logging drivers).
- Proficiency in creating and managing images, comprehending the structure of a Dockerfile, and adopting best practices for image creation.
- Knowledge of "Multi-stage builds" and their significance.
- Utilization of Docker Registry.
- Competence in using volumes.
- Understanding of Docker-related networking issues.
- Proficient management of running containers, monitoring their real-time status.

Audience profile
The training is intended for programmers, system engineers, and architects who want to build, run and manage containerized applications.
RequirementsBasic command-line navigation skills are required. In case you bring your own laptop, please ensure that ssh client is installed.
During the training, we will be creating/editing files on the server. Editors such as 'nano' and 'vim' will be available for editing purposes. Additionally, participants will have the option to mount a directory with tasks locally via ssh (e.g., VSCode offers suitable extensions for this purpose) and use their favorite editor from their local machine.
