Testcontainers-java: Could not connect to Ryuk at localhost:49154

[MaxWeinhart]

Hi,

I am using Docker Desktop on Windows 10.

Version 3.0.0 (50684)
Engine: 20.10.0
Compose: 1.27.4
Kubernetes: v1.19.3
Notary: 0.6.1
Credential Helper: 0.6.3
Snyk: v1.432.0

When running my test I see that the docker container for Ryuk is created and running.
But my test tells me "Could not connect to Ryuk at localhost:49154".

Can somebody help?

Thanks!

Hey, had the same issue with my projects, for some reason Ryuk started failing and I was only able to get my project to build by disabling ryuk via environment vars in Maven failsafe. e.g.

`

org.apache.maven.plugins

                 <artifactId>maven-failsafe-plugin</artifactId>
                 <executions>
                     <execution>
                         <goals>
                             <goal>verify</goal>
                             <goal>integration-test</goal>
                         </goals>
                         <configuration>
                             <argLine>@{argLine}</argLine>
                             <systemPropertyVariables>
                                 <java.security.egd>file:/dev/./urandom</java.security.egd>
                             </systemPropertyVariables>
                             <environmentVariables>
                                 <TESTCONTAINERS_RYUK_DISABLED>true</TESTCONTAINERS_RYUK_DISABLED>
                             </environmentVariables>
                             <trimStackTrace>false</trimStackTrace>
                         </configuration>
                     </execution>
                 </executions>
             </plugin>`

Also, supposedly using version 1.15.1 of test containers fixes this issue, but I didn't try that out yet.

Hi @abe546 ,

Disabling it via environment variable TESTCONTAINERS_RYUK_DISABLED did the trick.
At least the tests run again.

I also had to put the ip of registry-1.docker.io in /Windows/System32/drivers/etc/hosts file:

52.4.20.24 registry-1.docker.io

Still, it looks like a bug.

[MaxWeinhart]

Additional info: After running my test once with TESTCONTAINERS_RYUK_DISABLED=true i was able to run the tests again without this environment variable.

I don´t know why but now it works also without TESTCONTAINERS_RYUK_DISABLED=true.

[wallysoncarvalho]

Just started out with TestContainer and got the same error on my first run. Really disappointed. 😢

[almde89]

May I add something, as the issue still open? I've come to the same problem on Windows and Docker Desktop versions.
The thing is: localhost address was resolving to the IPV6, but the ports were accessable only through IPV4. Although the problem persisted only for the random port ranges. So, any given port, i.e. 49156, would not respond, even though I'd started the docker containers myself.

As a workaround - because disabling Ryuk would not resolve it at all, once ports still needed to test my API - I used an etc/hosts entry, forcing 127.0.0.1 address so I could point TESTCONTAINERS_HOST_OVERRIDE env to it and go ahead with my integration tests.

The only observations I have are that I'm using WSL2 plus MicroShed Test Framework and that I do not know if the first is interfering in some way.

[fb33]

Hello,

I've got the same issue : "Can not connect to Ryuk at localhost:xxxxx" due to a java.net.ConnectException: Connection refused

I'm on :

• Windows 10
• Docker Desktop 3.0.0 with WSL2
• Test Container Version 1.15.1

I'm running my tests with IntelliJ on windows not in WSL2

My workaround : disable WSL2 and switch back to hyper V

@fb33 , same situation here.
After my post, I didn't work on my code again. When I ran it today it worked, no change.

[bsideup]

Can somebody try adding -Djava.net.preferIPv4Stack=true to the JVM options and check whether it helps or not?

[fb33]

@wallysoncarvalho same here ! ;-)
I re-switched to WSL2 yesterday because I didn't use testportainer for the rest of the day.
And this morning I ran the tests using testportainer, it works !!...
Nothing change but it works fine today... weird...

Man... some kind of voodoo. Same @fb33 and @wallysoncarvalho here. I was trying to test your approach, @bsideup. It worked. But then I tried without it and it worked too.

My project was working some weeks before the problem came. It stopped suddenly.

If I could bet... Windows Updates. There are a lot of Windows Defender updates history amidst the time I was hit by the problem and now. I tested without Windows Firewall, but I did not disabled Defender for the tests in the past days. My bad.... apologies.

But the IPV6 and 4 tests I did It for real setting and unsetting TESTCONTAINERS_HOST_OVERRIDE to check my hypothesis. I tested the port ranges too. Running myself the containers with the random port ranges, i.e. 49154, and 18080. The latest worked and the earliest did not.

But, for sure, It is not a framework problem at all. I did test by that time on a Linux Virtual Machine and it worked too.

Same here. Thinks mentioned above does not help. It worked great few days ago. I also tried -Djava.net.preferIPv4Stack=true and disabling windows defender without luck.
Thx,
Ivos

edit: seems it is related to changed dynamic port range reservation by some windows update, see https://stackoverflow.com/a/64959783/535560

SOLUTION: after running netcfg -d from https://github.com/docker/for-win/issues/3171#issuecomment-731096674 and rebooting computer, testcontainers works again. windows woodoo detected :)

I have tested with pgsql container and it looks like that somethink have changed after some win-update.

edit 2:
I want just to note, that I am having this issue kind of regularly.

This does not work

docker ps
CONTAINER ID   IMAGE           COMMAND                  CREATED         STATUS         PORTS                     NAMES

with compose

    ports:
      - 5432

This works correctly

docker ps

with compose

    ports:
      - 5432:5432

when I choose large port range, i got error

    ports:
      - 49159:5432

Thanks bedla that worked great for me! Scary seeing all the network interfaces deleted but luckily it left my TAP adapters alone :)

I have the same problem with Docker Desktop 3.x on Windows 10 20H2 with WSL2.

I noticed that I always must start Docker containers with explicitly exposed ports, e.g., docker run -p 8080:8080....

Although it is not recommended, I tried to run my test container with fixed port-binding and deactivated Ryuk container - and it works:

In file testcontainer.properties:

ryuk.container.privileged = false

Environment variable:

TESTCONTAINERS_RYUK_DISABLED=true

In java test code (here Elasticsearch):

Consumer<CreateContainerCmd> cmd = e -> e.withPortBindings(new PortBinding(Ports.Binding.bindPort(9200), new ExposedPort(9200)));
elasticsearch = new ElasticsearchContainer(
    DockerImageName
        .parse(ELASTICSEARCH_CONTAINER_PROXY)
        .asCompatibleSubstituteFor(ELASTICSEARCH_CONTAINER)
    ).withExposedPorts(9200).withCreateContainerCmdModifier(cmd);

elasticsearch.start();

I suppose that this also may work with dynamic ports. Maybe you could solve this problem in the code by adding an option to use explicitly exposed (random) ports when starting the containers (and for the Ryuk container too)?

As for me, a restarted my Docker Desktop, and the issue has gone.

Yes, it works. But restarting docker several times a day isn't optimal solution.

[bsideup]

@0Prime please consider reporting to the Docker project as it seems to be something with Docker.

As it seems to be related to https://github.com/docker/for-win/issues/3171 (as @bedla pointed out), I will close this issue since there isn't something we can do about it.
