Overview

Docker SDK for Python

A Python library for the Docker Engine API. It lets you do anything the docker command does, but from within Python apps – run containers, manage containers, manage Swarms, etc.

Installation

The latest stable version is available on PyPI. Either add docker to your requirements.txt file or install with pip:

pip install docker

If you are intending to connect to a docker host via TLS, add docker[tls] to your requirements instead, or install with pip:

pip install docker[tls]

Usage

Connect to Docker using the default socket or the configuration in your environment:

import docker
client = docker.from_env()

You can run containers:

>>> client.containers.run("ubuntu:latest", "echo hello world")
'hello world\n'

You can run containers in the background:

>>> client.containers.run("bfirsh/reticulate-splines", detach=True)
<Container '45e6d2de7c54'>

You can manage containers:

>>> client.containers.list()
[<Container '45e6d2de7c54'>, <Container 'db18e4f20eaa'>, ...]

>>> container = client.containers.get('45e6d2de7c54')

>>> container.attrs['Config']['Image']
"bfirsh/reticulate-splines"

>>> container.logs()
"Reticulating spline 1...\n"

>>> container.stop()

You can stream logs:

>>> for line in container.logs(stream=True):
...   print(line.strip())
Reticulating spline 2...
Reticulating spline 3...
...

You can manage images:

>>> client.images.pull('nginx')
<Image 'nginx'>

>>> client.images.list()
[<Image 'ubuntu'>, <Image 'nginx'>, ...]

SSL: CERTIFICATE_VERIFY_FAILED error with boot2docker

Using the latest versions of docker-py and boot2docker I'm unable to make simple requests, receiving an SSL: CERTIFICATE_VERIFY_FAILED error.

Given the following test case.

> cat test.py
from docker.client import Client
from docker.utils import kwargs_from_env

kwargs = kwargs_from_env()

client = Client(**kwargs)
print client.version()

I get the following error:

Looking further, kwargs_to_env does appear to have picked everything up correctly:

And the referenced certs exist:

ls /Users/garethr/.boot2docker/certs/boot2docker-vm/
ca.pem   cert.pem key.pem

I'm using Python 2.7.9 on OSX.

Add device requests
Another take on #2395: while the Docker CLI adds a --gpus parameter, it is in fact syntatic sugar for the DeviceRequests argument in a container's host config. This PR adds support for any kind of device request, as it seems the API was designed to handle more in the future than just GPUs.

It would still be possible to support another gpus=... argument in a way similar to #2465, that could handle the previous nvidia runtime and set the environment variables itself or use the new device requests.

For example, with NVIDIA's test image, the equivalent of --gpus all would be:

client.containers.run( 'nvidia/cuda:9.0-base', 'nvidia-smi', device_requests=[ docker.types.DeviceRequest(count=-1, capabilities=[['gpu']]) ] )

The equivalent of --gpus 2 would be DeviceRequest(count=2, capabilities=[['gpu']]).

And for something like --gpus device=GPU-c6e298ba-aa33-4083-8ae3-db4e27037475,driver=nvidia,capabilities="utility,display":

client.containers.run( 'nvidia/cuda:9.0-base', 'nvidia-smi', device_requests=[ docker.types.DeviceRequest( driver='nvidia', device_ids=['GPU-c6e298ba-aa33-4083-8ae3-db4e27037475'], capabilities=[ ['gpu', 'utility', 'display'] ] ) ] )

tlsv1 alert protocol version on 1.7.1 and 1.7.2 but not on 1.7.0
Similar to #949 I'm discovering issues with latest versions of docker-py running against docker 1.10.2 instance. I'm using docker.utils.kwargs_from_env(assert_hostname=False). Things work fine with version 1.7.0.

Docker client is initialized via

client = docker.Client( version='auto', **docker.utils.kwargs_from_env(assert_hostname=False))

with docker environment variables being set to the following (via docker-machine)

DOCKER_HOST=tcp://192.168.156.137:2376 DOCKER_MACHINE_NAME=dev2 DOCKER_TLS_VERIFY=1 DOCKER_CERT_PATH=/Users/benjixx/.docker/machine/machines/dev2

docker-py 1.7.1 and 1.7.2 now raise the following exception:

DockerException: Error while fetching server API version: [Errno 1] _ssl.c:507: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

Any idea what's happening here?

Fix lost data & hangs when reading chunked streams
I managed to track down a hang when calling build() to a problem handling streams.

strace proved that the problem was somewhere in the python client and I manage to create a test harness for this issue.

This is not the most elegant fix, I could do with some advice:

I've changed the return value of attach_socket

In _stream_helper it creates a new fileobj, when we just threw away the one which had our data buffer in it, we could just keep the old one.

Fix to enable streaming container logs reliably

This patch is based on @kevinastone 's code in: https://github.com/docker/docker-py/issues/300#issuecomment-55320544

Started a ubuntu container that just runs "ping 8.8.8.8" and tried the sample code in https://gist.github.com/dims/c3327f633c526847c8e5 to recreate the problem mentioned in: https://github.com/docker/docker-py/issues/300

To debug the problem i printed the byte array read in recvall when reading STREAM_HEADER_SIZE_BYTES and realized that the data being read was far ahead of the actual start of the header documented in the vnd.docker.raw-stream of the docker remote api. This is possibly because the requests/urllib3 is reading ahead a bit more and we shouldn't be trying to hack the internals of those projects. So just using the documented file-like response.raw is good enough for us to get the functionality we need which is being able to read for exactly where the stream header starts. With this change i can reliably stream the logs just like "docker logs --follow".

Support for .dockerignore
According to https://docs.docker.com/reference/builder/#dockerignore you can have a .dockerignore file that prevents items from being ADDed. Mine looks like this:

.git

And then in my Dockerfile I have

ADD . /root/mycodes/

Unfortunately I still see /root/mycodes/.git in my container, which is sad because it's almost 300M. Is there any way to support this?

WIP: Adding nvidia-docker support
Currently just a proof of concept for nvidia-docker support, as discussed in docker/compose#4657

TL;DR;

It's working at least. Automatically used nvidia-docker mounts when starting a container with GPU support

There's a number of things I'm not 100% happy with yet.

Where I had to put the code (at the very least I should put it in its own function)

It's pretty fragile right now.

If you don't have nvidia on your host, it'll probably fail because devices don't exist

If you specify a bad GPU with NV_GPU it will fail. But this is the same behavior as nvidia-docker, this this is perhaps ok

If you want to disable the nvidia-docker support feature, there's nothing to do that with.

I'd like some guidance to these issues and what direction you would like me to go in.

Add utility to create a build context from a git repository.
The reason is because it won't work if you pass a private git repository as the build URL.

See docker/compose#2856 for more information, including a simple test-case by @zkf.

Instead, docker-py should follow the same steps as docker: if the build URL is a git repository, it should clone the repo locally and pass as a tarball to the daemon.

I believe the problem is caused by how docker-py performs a build (here) instead of following the same steps as docker.

Please let me know if I'm misunderstanding the problem or if there's any other way I can help.

hi,all! I ofen bind host files into containers by using "-v /path/to/host/file:/container/file:ro", when I using command line client. But now, I need to use docker-py to manage my containers. And I also need to do the same work:bind some host files into containers. And my code is like this (for example)

Weird behavior with follow=True blocking execution when running container exits
Environment:

OS: Ubuntu 22.04.1 LTS Docker Engine: 20.10.21 Python version: 3.10.6 docker-py: 6.0.1

Context

The Python script below runs wrapped by a GitLab runner process that is a CLI application written with Typer. The logging driver of Docker is journald

GitLab Runner: 15.6.1 Typer: 0.7.0

Question

I am trying to print logs from a running container. (it's execution is very fast)

import docker cli = docker.from_env() container = cli.containers.run(image=image, detach=True, remove=False) for cl in container.logs(stream=True, follow=True): typer.secho(cl.strip(), fg=typer.colors.BLUE) container.remove()

For a reason, container.logs(stream=True, follow=True) is acting weirdly whenever the detached container exits. Sometimes the execution of my program resumes and finishes properly and very often, the underlying container exits and my program get stuck in the for loop, doing nothing.

This has for consequence that jobs running in GitLab are timeouting due to no exit code of my cli.

It seems most likely system related since I can run the cli from my laptop without trouble. Any ideas from where the problem could come?

Add `network_driver_opt` to client.containers run and create

This pull request adds an additional parameter to client.containers.run and client.containers.create called network_driver_opt.

This parameter allows to specify a dict which allows to pass to the driver some custom values, and it is the same already present in Network.connect.

I requested this feature in #2896, but it was never implemented.

I think it could be useful to also export other parameters of networking_config.

Examples

Hi, it would be great if you guys could provide more example scripts for building specific images, automating docker container builds and running multiple commands inside a single container. Apologies if there are examples already, I haven't seemed to find many. I know in the documentation there are some line by line examples, but I didn't find them explanatory enough and I am struggling a fair bit with docker.

Can't start container. Unsure why

I’m trying to run docker at the moment from the python api. I’m just trying to make a container and then run commands using the exec_run command, however, my container seems to exit immediately after using the following:

import docker from docker.types import Mount

import os

client = docker.from_env() source_directory = "C:\Users\usr\data" target="/data" volume=os.getcwd() + "/data"

image_selected='openfoam/openfoam7-paraview56' container=client.api.create_container(image_selected) container=client.containers.get(container['Id']) print(container) container.start()

I’ve tried to add in a pause command with the following: container=client.api.create_container(image_selected, command="while true; do sleep 10000000; done")

and this doesn’t have any effect and the container still exits immediately.

I don’t suppose you would have any idea on how to troubleshoot. As far as I’m aware there are no errors that are outputted.

Here is the terminal output. I tried to use container.start() 2 times so that is why there are 3 of the initial messages:

Do you have any ideas?

6.0.0(Aug 18, 2022)
ℹ️ Upgrade Notes

Minimum supported Python version is 3.7+

When installing with pip, the docker[tls] extra is deprecated and a no-op, use docker for same functionality (TLS support is always available now)

Native Python SSH client (used by default / use_ssh_client=False) will now reject unknown host keys with paramiko.ssh_exception.SSHException

Short IDs are now 12 characters instead of 10 characters (same as Docker CLI)

Version metadata is now exposed as __version__

✨ Features

Python 3.10 support

Automatically negotiate most secure TLS version

Add platform (e.g. linux/amd64, darwin/arm64) to container create & run

Add support for GlobalJob and ReplicatedJobs for Swarm

Add remove() method on Image

Add force param to disable() on Plugin

🐛 Bugfixes

Do not accept unknown SSH host keys in native Python SSH mode

Use 12 character short IDs for consistency with Docker CLI

Ignore trailing whitespace in .dockerignore files

Fix IPv6 host parsing when explicit port specified

Fix ProxyCommand option for SSH connections

Do not spawn extra subshell when launching external SSH client

Features

Added support for multiplexed streams (for attach and exec_start). Learn more at https://docker-py.readthedocs.io/en/stable/user_guides/multiplex.html

Added the use_config_proxy parameter to the following methods: APIClient.build, APIClient.create_container, DockerClient.images.build and DockerClient.containers.run (False by default). This parameter will become True by default in the 4.0.0 release.
