Docker: doesn't work with requests-2.32.1

[ollie1]

A new version of the requests library has been released on pypi - https://pypi.org/project/requests/2.32.1/ . This seems incompatible with the docker molecule plugin. When trying to run molecule converge on a project using the docker plugin, I get a message as follows:

INFO     Sanity checks: 'docker'
CRITICAL Unable to contact the Docker daemon. Please refer to https://docs.docker.com/config/daemon/ for managing the daemon

Downgrading to a version of the requests library <2.32 resolves the issue and molecule works as normal:

python -m pip install 'requests<2.32'

Output of molecule --version

Same here with:

Please make sure to install community.docker 3.10.2 or newer (right now that's the latest version). It contains a fix for this issue.

I believe

molecule-plugins/src/molecule_plugins/docker/driver.py

Lines 270 to 273 in b48ead5

	def required_collections(self) -> dict[str, str]:
	"""Return collections dict containing names and versions required."""
	# https://galaxy.ansible.com/community/docker
	return {"community.docker": "3.4.11", "ansible.posix": "1.4.0"}

is still a problem however.

[felixfontein]

Ouch, yes, if it forces community.docker to 3.4.11, then well, you're totally out of luck. Then you need to stick to requests < 2.32.0.

Installing the community.docker collection at 3.10.2 manually before running molecule seems to work around the issue. Molecule doesn't force downgrade thankfully.

[MaxBidlingmaier]

manually updating community.docker did not fix it for me, had to downgrade requests to 2.30.0 (2.31.0 did not work either)
So working config for me:
pip:

• molecule==24.2.1
• molecule-plugins[docker]== 23.5.3
• requests==2.30.0
  Collections:
• community.docker-3.10.2

Also tried:
pip:

• molecule==24.6.0
• molecule-plugins[docker]== 23.5.3
• requests==2.31.0
  Collections:
• community.docker-3.10.3

After updating above config to requests 2.32.0 issue reoccured

[felixfontein]

@MaxBidlingmaier which parts of community.docker are you using (and which aren't working for you)? If you are using the Swarm modules, you must upgrade Docker SDK for Python as well.

Also I have never heard of problems with requests 2.31.0 so far. What are the exact problems you have with it?

(Also note that requests 2.32.0 has been yanked from PyPI. You should either use a version before that, or after that.)

@felixfontein : Just "normal" docker part (no swarm), see my molecule.yml below
