如何将卷映射到嵌入式 MariaDB 容器 - Java TestContainers with Spring

问题描述

我正在使用以下库从 Java Spring 应用程序启动嵌入式 maria DB 容器：

com.playtika.testcontainers.embedded-mariadb

https://mvnrepository.com/artifact/com.playtika.testcontainers/embedded-mariadb

第三方的这个类用于作为Spring bean启动容器：

@Slf4j
@Configuration
@ConditionalOnExpression("${embedded.containers.enabled:true}")
@AutoConfigureAfter(DockerPresenceBootstrapConfiguration.class)
@ConditionalOnProperty(name = "embedded.mariadb.enabled",matchIfMissing = true)
@EnableConfigurationProperties(MariaDBProperties.class)
public class EmbeddedMariaDBBootstrapConfiguration {
    @Bean(name = BEAN_NAME_EMBEDDED_MARIADB,destroyMethod = "stop")
    public MariaDBContainer mariadb(ConfigurableEnvironment environment,MariaDBProperties properties) throws Exception {
        log.info("Starting mariadb server. Docker image: {}",properties.dockerImage);

        MariaDBContainer mariadb =
                new MariaDBContainer<>(properties.dockerImage)
                        .withEnv("MYSQL_ALLOW_EMPTY_PASSWORD","yes")
                        .withUsername(properties.getUser())
                        .withPassword(properties.getPassword())
                        .withDatabaseName(properties.getDatabase())
                        .withCommand(
                                "--character-set-server=" + properties.getEncoding(),"--collation-server=" + properties.getCollation(),"--max_allowed_packet=" + properties.getMaxAllowedPacket())
                        .withExposedPorts(properties.port)
                        .withCreateContainerCmdModifier(cmd -> cmd.getHostConfig().withCapAdd(Capability.NET_ADMIN))
                        .withInitScript(properties.initScriptPath);
        mariadb = (MariaDBContainer) configureCommonsAndStart(mariadb,properties,log);
        registerMariadbEnvironment(mariadb,environment,properties);
        return mariadb;
    }

    private void registerMariadbEnvironment(MariaDBContainer mariadb,ConfigurableEnvironment environment,MariaDBProperties properties) {
        Integer mappedPort = mariadb.getMappedPort(properties.port);
        String host = mariadb.getContainerIpAddress();

        LinkedHashMap<String,Object> map = new LinkedHashMap<>();
        map.put("embedded.mariadb.port",mappedPort);
        map.put("embedded.mariadb.host",host);
        map.put("embedded.mariadb.schema",properties.getDatabase());
        map.put("embedded.mariadb.user",properties.getUser());
        map.put("embedded.mariadb.password",properties.getPassword());

        String jdbcURL = "jdbc:mysql://{}:{}/{}";
        log.info("Started mariadb server. Connection details: {}," +
                "JDBC connection url: " + jdbcURL,map,host,mappedPort,properties.getDatabase());

        MapPropertySource propertySource = new MapPropertySource("embeddedMariaInfo",map);
        environment.getPropertySources().addFirst(propertySource);
    }
}

这个类创建了 MariaDBContainer 类。

MariaDBContainer 扩展 GenericContainer，从 GenericContainer 类可以使用以下代码进行卷映射：

new GenericContainer(...)
        .withClasspathResourceMapping("redis.conf","/etc/redis.conf",BindMode.READ_ONLY)

问题是我无法修改EmbeddedMariaDBBootstrapConfiguration，它是com.playtika.testcontainers.embedded-mariadb 3rd 方的一部分。

您知道如何将卷映射到 maria db 嵌入式容器吗？
