Docker volumes
Don't use the constructor directly. Instead use
from python_on_whales import docker
my_docker_volume = docker.volume.inspect("my-volume")
# or
my_docker_image = docker.volume.create()
from python_on_whales import docker, Volume
def print_file(my_volume: Volume):
print(
docker.run(
"ubuntu",
["cat", "/some_volume/some_file"],
volumes=[(my_volume, "/some_volume/some_file")]
)
)
Attributes
It attributes are the same that you get with the command line:
docker volume inspect ...
To get a complete description of those attributes, you can take a look at the daemon api reference page and click on "200 No error".
An example is worth many lines of descriptions.

Methods
Volume
clone
clone(new_volume_name=None, driver=None, labels={}, options={})
Creates a new volume and copy all the data inside.
See the docker.volume.clone command for
information about the arguments.
exists
exists()
Returns True if the docker volume exists and False if it doesn't exists.
If it doesn't exists, it most likely mean that it was removed.
See the docker.volume.exists command for information about the arguments.
