Mount of volume-subpath which is available in Docker version 26.0.0, build 2ae903e using Python SDK for docker

Hi ,

I found a docker volume option “volume-subpath” in the Docker version 26.0.0. This could be used to mount a sub-directory or a sub-path inside a host docker volume to a container without mounting the entire host volume.

But while using Python SDK for docker, I am not able to use this volume option. Only source and target options were seen for docker volume configuartion using Python.

Is there any way to tackle this issue? I need this feature as part of a project developement. Please provide me some solution to implement this concept using Python.

We are developing in Linux 6.2.0-39-generic Ubuntu 22.04.1 with Python 3.10.12

Thanks in advance,

You should probably create an issue on Github.

Do you mean Docker SDK for Python? The latest version was released in december, 2023. SubPath was introduced in the engine API v1.45

  • POST /containers/create now supports VolumeOptions.Subpath which allows a subpath of a named volume to be mounted.

The current default API version in the SDK is 1.44 and default engine version is 25.0.

The SDK supports specifying the API version

https://docker-py.readthedocs.io/en/stable/client.html?highlight=version#docker.client.from_env

Parameters:

  • version (str) – The version of the API to use. Set to auto to automatically detect the server’s version. Default: auto

You can try that, but I wouldn’t be surprised if it didn’t work as Docker 26.0.0 is two weeks old and I don’t know how fast they make the SDK compatible with the latest versions.

Thanks for the information. We will look into it
