• What is a Filesystem Mapping in Docker

  In Docker, a file system mapping refers to the process of associating a directory or a file from the host system with a directory or a file inside a Docker container.

• What is a Port Mapping (Forwarding) in Docker

  In Docker, port mapping (also known as port forwarding) is the process of associating a port on the host system with a port on a Docker container, allowing network traffic to be directed to and from the container through the host system's network interface.

• How to Create and Use a Private Docker Registry

  Using a private Docker registry offers several benefits: You can create a private Docker registry to host and distribute your own Docker container images within your organization or for specific projects.

• What are Docker Networks

  Docker networks are virtual networks that provide communication channels for Docker containers to communicate with each other and with the host system, allowing containers to communicate securely and efficiently. Docker networks are used to isolate containers from the host system and from other containers, providing a controlled and secure environment for containerized applications.

• What are Docker Volumes

  Docker volumes are a way to persist and manage data in Docker containers. A Docker volume is a directory or a named volume that is stored outside of the container’s file system and is used to store and share data between Docker containers and the host system.

• What is Docker Compose

  Docker Compose is a tool that allows you to define, configure, and run multi-container Docker applications using a YAML file. It provides an easy way to define the services, networks, and volumes for your Docker containers in a single configuration file, which can be version-controlled and shared across teams.

• What is Docker Swarm

  Docker Swarm is a native container orchestration solution provided by Docker for managing and scaling containerized applications across a swarm of Docker nodes.

• What are Docker Image Registries

  Docker image registries are central repositories that store and distribute Docker container images. Docker container images are the building blocks of Docker containers, containing all the necessary files, libraries, and dependencies to run a containerized application.
