2. Explanation of Common Terms in Docker:

● Project (Docker Compose): Docker Compose is a tool for Docker specifically used to define and manage multi-container Docker applications, simplifying the deployment and management of complex applications. In short, it allows you to describe multiple services, networks, storage spaces, and other configurations of an application through a YAML file, and then start all services with a single command.
● Container: A container is a running image, which is the running entity of Docker. Through containers, you can run applications, with each container running independently in a relatively isolated environment, ensuring that multiple containers do not interfere with each other.
● Image: An image is the foundation of Docker containers, similar to a template for an application, containing the files and environment required for the application to run. Each time a container is created, it is generated based on an image. Images are read-only, and you can obtain various images from public repositories like Docker Hub or create your own images.
● Network (Network Mode): Docker supports multiple network modes. You can configure the container's network to share the network with the host as needed, or isolate the container from external networks through bridge mode.
