What are the main commands and tools used when working with Docker?

The most commonly used commands and tools when working with Docker are:

• docker build — creating an image from a Dockerfile.
• docker run — running a container from an image.
• docker ps — viewing running containers.
• docker images — viewing local images.
• docker stop and docker rm — stopping and removing containers.
• docker pull and docker push — downloading and uploading images to/from a registry.
• docker exec — executing commands inside a running container.

Tools:

• Docker CLI — the main command-line interface.
• Docker Compose — for describing and running multi-container applications via a YAML file.

Example of running a Python container:

docker run -it --rm python:3.9 python

This will start an interactive Python session inside the container.
