我有在docker容器中运行的测试。为此，我使用docker-dind服务，即.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，因此我添加了ES服务，但无法从运行测试的容器连接到ES群集。 当CI运行时，在装有跑步机的机器上我拥有：

598c019aa28c-一个带有跑步者的容器，我可以进入此容器运行curl "http://elasticsearch:9200"，它有效
57472d0300ad-垃圾容器，对吗？我可以进入该容器，但是curl "http://elasticsearch:9200"不起作用，docker ps显示：
/ # docker ps

如何将具有测试（252f0588a41d）的容器从ES连接到具有ES的容器？ 谢谢。
