Docker Network
Docker networking allows containers to communicate with each other and with external systems, providing isolation, security, and the ability to scale applications. It uses a pluggable architecture for networking, which means you can choose the best networking driver for your needs.
There are three common Docker network types:
Bridge networks: Used within a single host.
Overlay networks: For multi-host communication.
Macvlan networks: Used to connect Docker containers directly to host network interfaces.
Docker Volume
A Docker volume is a persistence mechanism for data generated by a running container. It's a file system that's mounted on a container, allowing the container to read and write data to the volume. The volume is stored on the host machine, outside of the container, so it persists even after the container is stopped or deleted.
Here are some of the benefits of using Docker volumes:
Persistent data: Data stored in a volume is persistent outside of the container, so it can be accessed even after the container is stopped or deleted.
Shared data: Volumes can be shared between multiple containers, allowing them to access the same data.
Backed up data: Volumes can be backed up, so you can restore the data if it's lost or corrupted.
There are a few different types of Docker volumes:
Host volumes:
Host volumes are directories on the host machine that are mounted on containers.
Named volumes:
Named volumes are volumes that are given a name, so they can be easily referenced and managed.
Anonymous volumes:
Anonymous volumes are volumes that are not given a name, so they are not persistent and are created and destroyed each time a container is created or stopped.
To create a Docker volume, you can use the docker volume create command
