Could you try Docker for Windows?

Couldn't get it working on a colleagues laptop with Windows and Docker Toolbox (Docker-Machine) last week as well, so might be a new compatibility issue with Docker Java Client and Docker Toolbox on Windows?

Try to enable following:

Thanks, that sounds like the solution for my colleague ;)

@alex120fantom Please provide further information if the problem persist, I'll close this issue for now.
The current usage instruction for Testcontainers on Windows are in the docs: https://www.testcontainers.org/usage/windows_support.html

Same problem here with similar errors:

Are you running Docker for Windows (Hyper-V) or Docker Toolbox (with VirtualBox)?

[DynamicBit]

Hi,
Iam running Docker for Windows (Hyper-V)

Is there a way to resolve this without exposing TCP, obviously don't want to be sitting with vulnerabilities on my end?? Did test that if i turn on the exposed option it does connect and seems to work.

[bsideup]

@WPanayides which version of Testcontainers are you using?

[mcpanayides]

@bsideup not sure about Testcontainers but using docker desktop

[bsideup]

@WPanayides I needed the Testcontainers version :)

[mcpanayides]

@bsideup I'm not using TestContainers i know this is a TC thread, but the issue i was having is exactly the same for Pycharm and the expose option can resolve it.

[bsideup]

@WPanayides I would suggest to discuss that in Pycharm's community then.

Testcontainers supports npipe and does not require exposing the TCP port.

[mcpanayides]

Cool thanks :-)
