Attempting to deploy with DeploymentImage results in "RuntimeError: This error is often thrown because Docker is not running." about prefect HOT 5 CLOSED

Did you by chance start using requests==2.32.0? I'm seeing the same thing when upgrading to that version. In my case, pinning to requests=2.31.0 resolved the issue for now.

See:

• psf/requests#6707

This seems to be an issue after requests was updated to 2.32.2. I also succeeded by installing any version below 2.32.2. In my case 2.31.0.

Hi there, I believe this can be closed by #13538. If not, feel free to comment and I can reopen it.

@ConstantinoSchillebeeckx this stems from a requirement of prefect - apprise

apprise has an unpinned/unbounded requirement for requests in their requirements.txt

Do you think this should be handled within the prefect requirements?

I encountered this issue as well and downgrading to requests==2.31.0 fixed the problem for me as well. However, can someone more knowledgable than me confirm that the prefect-docker python package doesn't accidentally inherit >2.31.0? If I take a look at my python dependency tree I can see the following:

prefect-docker==0.5.2
├── docker [required: >=6.1.1, installed: 6.1.3]
│   ├── packaging [required: >=14.0, installed: 24.0]
│   ├── requests [required: >=2.26.0, installed: 2.31.0] <------------ I manually installed 2.31.0 because 2.32 got automatically installed

To me it appears that it does indeed inherit whatever version pip decides to install (latest?) through the docker lib. It might be good to add a maximum allowed version of 2.31 to ensure that nobody else runs into this issue. Either way the issue is resolved for me now. Thanks for your help!
