The `lstrip` and `rstrip` functions take a set of characters to remove, not a prefix/suffix. Thus `rstrip('-x86_64')` will remove any trailing characters in the string `'-x86_64'` in any order (in effect it strips the suffix matching the regex `[-_x468]*`). So with `18.09.4` it removes the `4` suffix resulting in trying to `int('')` later on: Traceback (most recent call last): File "/src/scripts/versions.py", line 80, in <module> main() File "/src/scripts/versions.py", line 73, in main versions, reverse=True, key=operator.attrgetter('order') File "/src/scripts/versions.py", line 52, in order return (int(self.major), int(self.minor), int(self.patch)) + stage ValueError: invalid literal for int() with base 10: '' Since we no longer need to check for the arch suffix (since it no longer appears in the URLs we are traversing) we could just drop the `rstrip` and invent a local prefix stripping helper to replace `lstrip('docker-')`. Instead lets take advantage of the behaviour of `re.findall` which is that if the regex contains a single `()` match that will be returned. This lets us match exactly the sub-section of the regex we require. While editing the regex, also ensure that the suffix is precisely `.tgz` and not merely `tgz` by adding an explicit `\.`, previously the literal `.` would be swallowed by the `.*` instead.

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'>, ...]
