docker
`client.containers.run()` doesn't exist
Hi there,
Today I decided to look into docker-py for a project I will be working on in the coming months. After a fresh install of docker and docker-py today, I must say that, somehow, docker-py doesn't quite work. The getting started examples show this code:
>>> import docker
>>> client = docker.from_env()
>>> client.containers.run("ubuntu", "echo hello world")
'hello world\n'
But when I run this, I see
In [1]: import docker
In [2]: client = docker.from_env()
In [3]: client.containers.run("ubuntu", "echo hello world")
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-3-5336699d83c5> in <module>
----> 1 client.containers.run()
AttributeError: 'function' object has no attribute 'run'
I also tried to manually create an instance of the docker.Client as detailed in the docs
In [1]: import docker
# Note: The following line from the docs fails to execute... :-(
In [2]: client = docker.DockerClient(base_url='unix://var/run/docker.sock')
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-2-a0131c4bce50> in <module>
----> 1 client = docker.DockerClient(base_url='unix://var/run/docker.sock')
AttributeError: module 'docker' has no attribute 'DockerClient'
In [3]: client = docker.Client(base_url='unix://var/run/docker.sock')
In [4]: client.containers.run("hello-world")
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-4-a00eac6bdc71> in <module>
----> 1 client.containers.run("hello-world")
AttributeError: 'function' object has no attribute 'run'
Calling docker through the CLI works as expected
$ docker run hello-world
Hello from Docker!

Here's some info on my system:

I'd be grateful for any help and/or pointers to a possible cause...
You probably installed docker-py from PyPi which is an old version from 2016.
Remove it and install docker instead from PyPi.
Both modules are imported as import docker but the old one doesn't have the run() method.
I just ran against this issue myself.
