docker - GitLab CI，从 docker dind 连接到 Elastic Search 服务

Question

我有在 docker 容器中运行的测试。为此，我使用 docker-dind 服务，我的 .gitlab-ci：

image: "docker:17"

variables:
  DOCKER_DRIVER: overlay2

services:
  - docker:dind
  - name: docker.elastic.co/elasticsearch/elasticsearch:5.5.2
    alias: elasticsearch
    command: [ "bin/elasticsearch", "-Expack.security.enabled=false", "-Ediscovery.type=single-node" ]

stages:
  - test

before_script:
  - apk --update add py2-pip python3 bash zip ansible openssh git docker-py curl
  - pip3 install docker-compose
  - docker info
  - docker-compose --version
    # Login to registry.gitlab.com
  - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com

test:
  script:
    - curl "http://elasticsearch:9200" # this works
    - docker-compose docker-compose.test.yml build --pull
    - docker-compose docker-compose.test.yml run app
  stage: test

我的测试为此使用 ES 我添加了 ES 服务，但我无法从运行测试的容器连接到 ES 集群。当 CI 工作时，在我的带有跑步者的机器上，我有：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                  PORTS                NAMES

598c019aa28c - 一个带有跑步者的容器，我可以进入这个容器运行curl "http://elasticsearch:9200"并且它可以工作

57472d0300ad - dind 容器，对吧？我可以进入这个容器但curl "http://elasticsearch:9200"不起作用，docker ps 显示：

/ # docker ps
CONTAINER ID        IMAGE                   COMMAND                  CREATED             STATUS              PORTS               NAMES

如何从带有测试（252f0588a41d）的容器连接到带有 ES 的容器？谢谢。
