java.lang.IllegalStateException: Could not connect to Ryuk at localhost:49167

Question

I am using test containers library to launch a container. It worked for a while but currently running into this

java.lang.IllegalStateException: Could not connect to Ryuk at localhost:49167

    at org.testcontainers.utility.ResourceReaper.start(ResourceReaper.java:201)
    at org.testcontainers.DockerClientFactory.client(DockerClientFactory.java:205)
    at org.testcontainers.LazyDockerClient.getDockerClient(LazyDockerClient.java:14)
    at org.testcontainers.LazyDockerClient.authConfig(LazyDockerClient.java:12)
    at org.testcontainers.containers.GenericContainer.start(GenericContainer.java:310)

I looked at the resource reaper code and it seems like it is failing here

public synchronized void performCleanup() {
    this.registeredContainers.forEach(this::stopContainer);
    this.registeredNetworks.forEach(this::removeNetwork); //FAILS HERE
    this.registeredImages.forEach(this::removeImage);
}

which Testcontainers version are you using and can you please add the code for your failing test? — rieckpil, May 06 '21 at 04:38
When I restarted docker the problem went away but that is me shooting blind. May I know what is causing this issue? Because this problem persisted for a while — user1870400, May 06 '21 at 11:27
Without being able to reproduce the issue again it's quite hard to say what issue caused this. What's your Docker version? — rieckpil, May 07 '21 at 06:17

I tried everything mentioned here but nothing worked.

If anyone is still facing the issue they can give this one a try... this worked for me.

This works for windows:

open you PowerShell in administrator mode.
run net stop winnat
run net start winnat

Doing this resolved this issue on my setup. Hope this helps someone.

I can confirm that this is resolved by updating testcontainers to 1.16.0 version

Was facing the same exception with testcontainers 1.15.3

Windows 10, Docker desktop 4.0.0

I ran into the same issue. Same Docker-for-Mac version.

Solution for me was to disable "Use gRPC FUSE for file sharing" in Preferences:

For me, restarting the local docker engine solved the problem

indeed: "sudo service docker restart" solved the problem. – reencode Apr 26 '22 at 07:07

I am using colima and stopping starting colima did the trick: `colima stop` `colima start` – Sahil Jain Jun 21 '23 at 21:14

I'm on a Windows 11 machine with the same issue:

It turned out that a vast number of ports were allocated by the service "IP helper" (relates to ipv6 support), i.e. ports prior allocated by testcontainers, or other services. They were allocated for weeks by Ip helper but never, or rarely, released. By permanently disabling service Ip helper all issues were resolved and the set-up works great since then without any observed side effects that I am in need of.

Setting: Windows11 + Rancher Desktop

Restarting Rancher Desktop did not help. However, restarting my computer did the job.

For me was helpful this comment: https://github.com/testcontainers/testcontainers-java/issues/3609#issuecomment-769615098

In file testcontainer.properties at your user folder add:

ryuk.container.privileged=false

Set environment variable for your user:

TESTCONTAINERS_RYUK_DISABLED=true
