How do you assess your level of knowledge and experience with Docker?

The assessment of knowledge level and work experience with Docker depends on several factors:

• Understanding of basic concepts: containers, images, Dockerfile, application containerization.
• Ability to create and optimize Dockerfile for various applications.
• Experience with Docker Compose for orchestrating multiple containers.
• Skills in deploying containers in different environments (locally, on a server, in the cloud).
• Knowledge of Docker CLI commands and debugging containers.

For example, for a junior level, it is enough to be able to create simple Dockerfiles and run containers, while for a middle level — work with Docker Compose, optimize images, and integrate Docker into CI/CD processes.

If you can independently prepare a container for a PHP application, set up an environment with a database, and debug containers — this is already a good level for a middle.
