Docker Objects are the discrete entities or resources that the Docker Daemon manages. These are the building blocks of Docker.
Images: A read-only template with the instructions for creating a container. A snapshot of your app — like a recipe.
Containers: A runnable instance of an image. A live app built from the image — like a dish cooked from a recipe.
Volumes: Persistent storage used by containers to store data outside of the container’s filesystem. Think of it as a hard drive for containers — survives restarts or rebuilds.
Networks: Allow containers to communicate with each other and with the outside world. Docker creates a default bridge network, but you can define your own.
Plugins: Plugins allow you to extend Docker's capabilities. you might use a Storage Plugin to connect your containers directly to AWS EBS or an S3-backed filesystem, or a Logging Plugin to stream your Node.js logs directly to CloudWatch or ELK.
