What is Docker Volume? Getting started with Docker Volume. Basic Commands.

What is Docker Volume?
Docker volumes are widely used and useful tools for ensuring data persistence while working in containers. They are a better alternative than compiling additional writable layers, which increase Docker image size.

Getting Started With Docker Volumes
There are different ways to mount a Docker volume while launching a container. Users can decide between the -v and the --mount flags, which are added to the docker run command.

Basic Commands:

To create a Docker Volume use the command:
docker volume create [volume_name]
#Docker automatically creates a directory for the volume on the host under the /var/lib/docker/volume/ path.

docker volume create volume_test

Mounting a Host Directory as a Data volume
docker run -it --name=Container1 --mount source=volume_test,destination=/volume_test ubuntu
cd volume_test
touch welcome1.txt
exit
docker run -it --name=Container2 --mount source=volume_test,destination=/volume_test ubuntu
ls
cd volume_test
#welcome1.txt file is going to be avaliable in folder volume_text of another container(Container2)

Arguments --mount and --volume is similar:

docker run --volume "$(pwd)":[volume_name] [docker_image]

The "$(pwd)" attribute instructs Docker to mount the directory the user is currently in.

mkdir tmp
cd tmp

docker run -it -v "$(pwd)":/volume_test1 ubuntu
ls
cd volume_test1

To verify you have successfully created a Docker volume, prompt Docker to list all available volumes with:
docker volume list

It lists details of a volume, including its location on the host file (Mountpoint). Everything stored within the data volume can also be found in the directory listed under the mountpoint path.

Returns information about a volume. By default, this command renders all results in a JSON array.
docker volume inspect [volume_name]

Docker removes volumes only if they are not in use at the moment.
docker volume rm [volume_name]

To delete all unused Docker volumes with a single command:
docker volume prune
