Testcontainers-java: an not connect to Ryuk

[lburgazzoli]

I'm working on upgrading testcontainers to the latest version (1.12.0) in etcd-io/jetcd and after the upgrade I'm not more able to run tests because of:

I think @jonathanvila had the same issue, but not related to the upgrade.

Is it consistent and breaks only with 1.12.0, but works with 1.11.4?

[lburgazzoli]

I got it from ci so I assumed it was working before, let me try

[lburgazzoli]

same issue also on 1.11.4

@jonathanvila has reported a success after replacing "docker" package (2.5y.o., version 1.13.1) with "docker-ce" (the latest stable)

[lburgazzoli]

I have docker from fedora:

$ rpm -qa | grep docker
docker-1.13.1-67.git1185cfd.fc30.x86_64
docker-rhel-push-plugin-1.13.1-67.git1185cfd.fc30.x86_64
docker-common-1.13.1-67.git1185cfd.fc30.x86_64

[lburgazzoli]

I'm a little bit reluctant to install from docker itself as for example it does not list fedora 30 in the installation instructions:

 https://docs.docker.com/install/linux/docker-ce/fedora/

And they are quite slow to provide a package for the latest version, i.e. the version for fedora 30 is available only since a few days even if fedora 30 is out since some months

Thanks for confirming that it is not 1.12.0 specific 👍

I think your colleagues were having the same sort of conversation about "docker" vs "docker-ce" here, and came to the conclusion that "docker-ce" is fine. You may want to follow their conversation :)

[lburgazzoli]

so yeah, setting the property works

@lburgazzoli thanks again for confirming! 💯
