How is the Docker image distributed among teams or in the repository?

Distribution of Docker images among teams or in repositories occurs through Docker Registry — a centralized storage for images.

The process typically involves:

1. Building the image: a developer or CI/CD system builds the Docker image locally.
2. Tagging the image: the image is assigned a tag, usually indicating the registry address and repository name, for example registry.example.com/project/app:tag.
3. Publishing (push): the image is uploaded to the Docker Registry using the docker push command.
4. Access and download (pull): other team members or systems can download the image using docker pull.

Example commands:

docker build -t registry.example.com/project/app:1.0 .
docker push registry.example.com/project/app:1.0
docker pull registry.example.com/project/app:1.0

For public images, Docker Hub is often used; for private images, corporate registries (e.g., Harbor, GitLab Container Registry, AWS ECR) are used. This ensures centralized access, version control, and security.
