Study Notes
Containerization in Docker
- A container includes an application, its dependencies, and settings, but not a full-fledged operating system.
- The purpose of a container image is to provide a lightweight, stand-alone, and executable package of software that includes everything an application needs to run.
- Docker uses a standardized format, the Dockerfile, which is used by both developers and operation teams.
Roles of Operating Systems
- The operating system running in the container provides a minimal set of services and libraries, and is not a full-fledged operating system.
- The operating system running on the host provides underlying services, such as process scheduling, memory management, and networking.
Docker Images
- The main purpose of Docker images is to provide a template for containers, including the application code, libraries, dependencies, and settings.
- Docker images are not containers, but rather a blueprint for creating containers.
Software, Packages, and Images
- Software refers to the application code, including dependencies and settings.
- Packages are libraries and dependencies required by the application.
- Images are templates that include software, packages, and settings, and are used to create containers.
Test your knowledge on how Docker images work and the differences between software, packages, and images in Docker. Improve your understanding of containerization and distribution of applications.
