Hello everyone, I am having some troubles with volume mounts (FileSystemBinds and ClassPathResourceMapping) on Gitlab CI. My container: OMN_WEB = new GenericContainer<>(DockerImageName.parse(OMN_WEB_API_IT_IMAGE_NAME))
.withExposedPorts(OMN_WEB_PORT)
.withNetwork(network)
.withNetworkAliases(OMN_WEB_ALIAS)
.dependsOn(LDAP, DB)
.withEnv("CATALINA_OUT", DEV_STDOUT) // log to stdout
.withEnv("TOMCAT_STDOUT", DEV_STDOUT) // log to stdout
.withClasspathResourceMapping("config",
OMN_CONFIG_FOLDER,
BindMode.READ_ONLY) // read only copies files and in result leaves already existing ones
.withClasspathResourceMapping(DB_PROPERTIES_FILE_SOURCE,
OMN_CONFIG_FOLDER + "/" + DB_PROPERTIES_FILE_TARGET,
BindMode.READ_ONLY)
.withClasspathResourceMapping(OMN_WEB_CONF,
OMN_ETC_FOLDER + "/" + OMN_WEB_CONF,
BindMode.READ_ONLY)
.withClasspathResourceMapping("libs/",
OMN_PLUGINS_FOLDER,
BindMode.READ_WRITE) // read write mounts folder and therefore overwrites existing folder
.withClasspathResourceMapping("jdbc",
OMN_JDBC_DRIVER_FOLDER,
BindMode.READ_WRITE)
.withFileSystemBind("logs", OMN_WEB_LOG_FOLDER) // logs are in omn4-api-app/logs for debug purposes
.withFileSystemBind(DockerClientFactory.instance().getRemoteDockerUnixSocketPath(), "/var/run/docker.sock", BindMode.READ_WRITE)
.withLogConsumer(new Slf4jLogConsumer(LoggerFactory.getLogger(OMN_WEB_ALIAS)))
.waitingFor(Wait.forHttp(OMN_API_VERSION_ENDPOINT).forPort(OMN_WEB_PORT).forStatusCode(403)
.withStartupTimeout(Duration.ofMinutes(4)));
OMN_WEB.start();My Gitlab CI yml: image: maven:3.5.3-jdk-8

Hi @shomeier, For the volume binds to work, you need to make sure that tests' file system matches Docker's. See https://www.testcontainers.org/supported_docker_environment/continuous_integration/dind_patterns/ Also, have you considered using the copy API instead of mounting files? It is generally preferred and recommended, as it works with any Docker, not only with local one |

Hi @bsideup, at first thx for your answer. Regarding the tests' filesystem: Regarding the copy API: |
