测试容器：忽略来自Dockerfile的父“EXPOSE”指令

我正在尝试通过具有固定公开端口的测试容器运行 Couchbase v.5.1.1 docker 容器以进行测试，例如：

trait CouchbaseTestEnvironment extends ForAllTestContainer {
  this: Suite =>

  def couchbaseContainer: FixedHostPortGenericContainer = {
    val consumer = new Slf4jLogConsumer(LoggerFactory.getLogger(getClass))

    /*
     * Couchbase should know which ports are exposed for client, because this is how it exposes services.
     * E.g. client ask only for on port - say 8091. And query service port is 8093. So client, won't ask for every port,
     * instead CB will tell client on which port query service exposed, that's why CB should be aware about port mapping.
     * That's why we need to give CB port mappings
     *
     * See for more details:
     * /sf/ask/4149420551/
     */

    def randomPort: Int = {
      val (from, to) = (32768, 35000) //linux private port range
      from + Random.nextInt(to - from)
    }

    val random8091Port = randomPort
    val random8092Port = randomPort
    val random8093Port = randomPort
    val random8094Port = randomPort
    val random11210Port = randomPort

    val container = FixedHostPortGenericContainer(
      imageName = "couchbase:community-5.0.1",
      exposedHostPort = random8091Port,
      exposedContainerPort = random8091Port,
      env = Map(
        "COUCHBASE_RANDOM_PORT_8091" -> random8091Port.toString,
        "COUCHBASE_RANDOM_PORT_8092" -> random8092Port.toString,
        "COUCHBASE_RANDOM_PORT_8093" -> random8093Port.toString,
        "COUCHBASE_RANDOM_PORT_8094" -> random8094Port.toString,
        "COUCHBASE_RANDOM_PORT_11210" -> random11210Port.toString
      )
    )

    container.container.withFixedExposedPort(random8092Port, random8092Port)
    container.container.withFixedExposedPort(random8093Port, random8093Port)
    container.container.withFixedExposedPort(random8094Port, random8094Port)
    container.container.withFixedExposedPort(random11210Port, random11210Port)

    container.container.withLogConsumer(consumer)

    container
  }
}

如您所见，应该公开 5 个 FIXED 端口。但是，当我运行测试时，我实际上可以看到，而是使用随机端口公开的其他端口：

docker ps

f4fc1ce06544   couchbase:community-5.0.1   "/entrypoint.sh /opt…"   59 seconds ago   Up 1 second    0.0.0.0:55264->8091/tcp, 0.0.0.0:55263->8092/tcp, 0.0.0.0:55262->8093/tcp, 0.0.0.0:55261->8094/tcp, 0.0.0.0:55260->11207/tcp, 0.0.0.0:55259->11210/tcp, 0.0.0.0:55258->11211/tcp, 0.0.0.0:55257->18091/tcp, 0.0.0.0:55256->18092/tcp, 0.0.0.0:55255->18093/tcp, 0.0.0.0:55254->18094/tcp   unruffled_mendel
03b491ac2ea8   testcontainersofficial/ryuk:0.3.0

所以你可以看到另一个端口被暴露，并映射到随机端口而不是固定的。

据我了解，测试容器会忽略我提供的端口，而是从 Couchbase Dockerfile 公开端口：https : //github.com/couchbase/docker/blob/master/community/couchbase-server/5.1.1/Dockerfile# L74

EXPOSE 8091 8092 8093 8094 8095 8096 11207 11210 11211 18091 18092 18093 18094 18095 18096

我可以以某种方式强制测试容器忽略EXPOSE指令吗？

部分帮助的问题：用于集成测试的 docker 中的 Couchbase：使端口 8092、8093、8094 和 8095 可配置为能够使用 docker 的随机端口
