I am using test containers and it used to work fine until now. I recently updated docker and IntelliJ, but I do not know if this is the cause of the following issue.

This are the dependencies I used:

testCompile 'org.testcontainers:testcontainers:1.12.3' testCompile 'org.testcontainers:oracle-xe:1.12.3'

This is the stacktrace:

Does anyone know how to solve this issue?

Thank you in advance.

  • Can you add the result of docker ps and docker images command in the question? Commented Oct 12, 2020 at 14:48
  • @wak786 I found the answer. Looks like there is a problem in docker 2.4.0 for mac Commented Oct 12, 2020 at 15:03

The issue was caused by the new docker version. In case you updated docker to 2.4.0 then there are a few options you can try.

  1. switch the "Use gRPC FUSE for file sharing" option off in docker preferences.
  2. update the testcontainers to 1.15.0-rc2
  3. downgrade docker to 2.3.x

I tried the first option and it worked for me.

I use a mac. I do not know if there is a similar issue on other platforms.

@Andrey it worked for me too, but I have the impression it runs slower. Do you experience such issues?
Just FYI - in newer docker version for mac, switch from "gRPC FUSE" to "osxfs (Legacy)" to fix that issue.

I had the same issue on Mac OS X with testcontainers for Java and Colima. This solved it for me:

sudo ln -sf $HOME/.colima/default/docker.sock /var/run/docker.sock export TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE=/var/run/docker.sock
