Quarkus / Testcontainers and Docker 29 not working

[ontec-xrail]

I use Rancher Desktop in my Windows Environment and I am pretty happy with it - in the latest version it upgraded to docker 29:

• Rancher Desktop: 1.22.0
• docker version: Docker version 29.1.4-rd, build 3c6914c
• Quarkus version 3.33.1 (comes with testcontainers 2.0.3)

I know its not really a Quarkus issue but I am struggling getting testcontainers working with docker 29 - I always need to downgrade to testcontainers 1.21.4.

I get the following error although docker is running fine:

Is there any fix for that? Except downgrading docker to 28?

Thanks Max

Seems like we are unable to recongize this setup. I don't use windows myself. @gastaldi, are you able to check?

[gastaldi]

I don't have a Windows environment, only in a VM (which doesn't work with Docker containers very well). @gsmet 's suggestion in #53544 (comment) makes sense as this does not seem to be really specific to Quarkus itself

[gsmet]

I think the first step is to isolate the issue and see if it's reproducible with pure Testcontainers outside of Quarkus.

If it is then I would suggest to open an issue on the Testcontainers side. If it's not then we will have to dig on our side.

[itidelch]

I faced same issue on windows, with Rancher Desktop and Docker desktop
