"Can not connect to Ryuk" on macOS with Docker for Mac 2.4.0.0 #3166
Description
I've seen this exact error come and go a fair bit on here, but it's just today started happening for me.
I'm using testcontainers-java 1.12.0, but updating to the latest version has no impact at all.
When running my test, I get the following:
2020-08-28 17:19:18.778,INFO ,[main]:,o.t.d.DockerClientProviderStrategy,,,,,Loaded org.testcontainers.dockerclient.UnixSocketClientProviderStrategy from ~/.testcontainers.properties, will try it first

And then a seemingly infinite amount of the following:

This is running with Java 1.8.0_222 from Amazon Corretto, running on macOS 10.15.6.
This definitely worked yesterday. I did have an update to the Docker Engine today, and I'm assuming that's relevant, but everything else I'm doing with Docker is all working fine - including a different project that uses the Rust version of TestContainers. (Though I notice that doesn't use Ryuk, which might be relevant)

@sazzer Have you found a solution in the meantime? I have the same issue after updating Docker Engine today.
Edit: "Downgraded" from Docker Desktop Edge to Docker Desktop Stable and the issue has gone. Looks like a problem in combination with Docker 2.3.6.0.
gesellix commentedon Sep 7, 2020
For the recent Docker Desktop 2.4.x Release on macOS, see #3159.

I'm on MacOS 10.14.6 (Mojave).
Both TestContainers v1.12.3 and the latest (v1.14.3) have ceased to work with the latest update of Docker that I received today. The exact same symptoms as the OP happen.
Version 2.4.0.0 (48506) from the "stable" Channel.
Engine is: 19.03.13
Anyone found this and/or have a workaround, short of downgrading/rolling back the version of Docker Desktop (Community)?

I'm also experiencing the same issue

Docker for Mac 2.4.0.0 was released yesterday, pushing this issue into the stable version.
We released 1.15.0-rc2 which includes a fix (#3159) for compatibility - please upgrade.
telapo commentedon Oct 1, 2020
No-one has asked me, but I confirm that 1.15.0-rc2 works ;-)
tmohme commentedon Oct 1, 2020
Same here: 1.15.0-rc2 solves the problem.
Thanks for the fast reaction 👍

I have the same issue.
Using 1.15.0-rc2 could be a workaround. It's available in maven central.

schophil commentedon Oct 1, 2020
1.15.0-rc2 works for me to.
I do have some questions regarding this topic:
When will 1.15.0 be released?
What is the impact of not using ryuk?

Containers will not terminated.

This issue is about Docker for Mac 2.4.0.0 only. The error message ("can not connect to <...>") itself does not mean that you're having the same issue.
Consider creating a new issue if you're having issues with 1.15.0-rc2.
For those who are searching for a fix, see this comment:

One further update: 1.15.0 was released today including the fix (the same as the previous RC builds)
