io.etcd.jetcd.launcher.EtcdContainer -- Error deleting directory when using jetcd-tests on unit-testing.

  • etcd: 3.5.10
  • jetcd: 0.7.7
  • java: 21

Describe the bug At the end of unit tests when using jetcd-tests, an error io.etcd.jetcd.launcher.EtcdContainer -- Error deleting directory is thrown. It doesn't prevent the test to run successfully, but I wonder if it's something wrong I'm doing.

To Reproduce

import io.etcd.jetcd.ByteSequence;
import io.etcd.jetcd.Client;
import io.etcd.jetcd.KV;
import io.etcd.jetcd.kv.GetResponse;
import io.etcd.jetcd.kv.PutResponse;
import io.etcd.jetcd.test.EtcdClusterExtension;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.RegisterExtension;

import java.nio.charset.StandardCharsets;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutionException;

public class SimpleTest {

    @RegisterExtension
    public static final EtcdClusterExtension cluster = EtcdClusterExtension.builder()
            .withNodes(1)
            .build();

    Client client = Client.builder().endpoints(cluster.clientEndpoints()).build();

    @Test
    public void testing() throws ExecutionException, InterruptedException {
        KV kvClient = client.getKVClient();
        CompletableFuture<PutResponse> put = kvClient.put(ByteSequence.from("a", StandardCharsets.UTF_8), ByteSequence.from("v", StandardCharsets.UTF_8));
        put.join();
        CompletableFuture<GetResponse> get = kvClient.get(ByteSequence.from("a", StandardCharsets.UTF_8));
        Assertions.assertEquals(get.get().getCount(), 1);
    }

Expected behavior It is expected that this AccessDeniedException don't appear at all.

Additional context

  • The tests are running successfully.
  • Using JUnit 5 with jetcd-tests and jetcd-launcher. Docker version is 25.0.1, as shown in the logs

  • I noticed this issue at https://github.com/apache/shardingsphere/pull/30003 when trying to convert org.testcontainers.containers.GenericContainer to io.etcd.jetcd.test.EtcdClusterExtension. Then I checked https://github.com/etcd-io/jetcd/blob/jetcd-0.7.7/jetcd-launcher/src/main/java/io/etcd/jetcd/launcher/EtcdContainer.java .

  • The default value of shouldMountDataDirectory of io.etcd.jetcd.launcher.EtcdContainer is true. Once shouldMountDataDirectory is true, io.etcd.jetcd.launcher.EtcdContainer.configure() will start mounting files to the actual directory.

if (shouldMountDataDirectory) {
    dataDirectory = createDataDirectory(node);
    addFileSystemBind(dataDirectory.toString(), Etcd.ETCD_DATA_DIR, BindMode.READ_WRITE, SelinuxContext.SHARED);
}

  • To be honest, I can't think of a reason why the directory needs to be mounted by default. Because using the Docker Image of quay.io/coreos/etcd does not require this.

  • Of course, there is an option for io.etcd.jetcd.test.EtcdClusterExtension to modify all subcontainers. So here's my thinking.

@RegisterExtension
public static final EtcdClusterExtension CLUSTER = EtcdClusterExtension.builder()
            .withNodes(1)
            .withMountDirectory(false)
            .build();
  • @lburgazzoli I noticed recently that it's you who changed https://github.com/etcd-io/jetcd/blob/jetcd-0.7.7/jetcd-launcher/src/main/java/io/etcd/jetcd/launcher/EtcdContainer.java , can we change the default value of the shouldMountDataDirectory property to false? Because when unit tests are executed under GraalVM Native Image, the permissions of external files are usually designed not to be changed, see https://github.com/oracle/graal/issues/7860 .

This is something that has nothing to do with the requirement of the container image but it is something implemented for our test suite which for some tests requires to manipulate the content of the data dir.

* @lburgazzoli I noticed recently that it's you who changed https://github.com/etcd-io/jetcd/blob/jetcd-0.7.7/jetcd-launcher/src/main/java/io/etcd/jetcd/launcher/EtcdContainer.java , can we change the default value of the `shouldMountDataDirectory` property to `false`? Because when unit tests are executed under GraalVM Native Image, the permissions of external files are usually designed not to be changed, see [`java.nio.file.Files#setPosixFilePermissions` cannot be used under Native Image oracle/graal#7860](https://github.com/oracle/graal/issues/7860) .

Before changing the behavior, you need to check what the current test suite is doing.

In any case, this does not solve the issue but just hide it so it would be nice to find out if there is a way to make it working regardless of the flag.
