使用Maven在gitlab中运行（Docker）测试容器

我在gitlab ci/cd管道中工作。此管道使用maven和docker执行其所有命令（不包括部署）。在本例中，我尝试运行集成测试（由maven启动），它使用一个测试容器（用于mysql数据库）。这些测试在本地运行时运行良好。然而，当我试图从gitlab运行它们时，遇到了一些问题。我相当确定我的问题是我没有访问docker的权限（但是，在本例中，我需要我的映像同时具有docker和maven）

以下是gitlab文件的适用部分：

#This phase is only run when merging (to master) 
merge_tests:
 image: maven:latest
 stage: mvn_build_and_test
 #TODO can remove services if this does not work    without docker image as base image
  services:
  - docker:stable-dind
 #set variables for use later when running maven in script section
variables:
  MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
  MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"  
script: 
  #ONLY RUN WHEN MERGE REQUEST IS TO MASTER BRANCH
  #if ["$CI_MERGE_REQUEST_TARGET_BRANCH_NAME" == "master"]; then 
  #check docker is installed and running
  #- docker --version #this fails if uncommented
  - mvn $MAVEN_CLI_OPTS clean install -Pintegration-test-profile
  #; fi   
#only:
 #- merge_requests

以下是gitlab上的错误堆栈跟踪：

 org.testcontainers.containers.ContainerLaunchException: Container startup failed
1958 Caused by: org.testcontainers.containers.ContainerFetchException: Can't get Docker image: RemoteDockerImage(imageNameFuture=java.util.concurrent.CompletableFuture@21baa903[Completed normally], imagePullPolicy=DefaultPullPolicy(), dockerClient=LazyDockerClient.INSTANCE)
1959 Caused by: java.lang.IllegalStateException: Could not find a valid Docker environment. Please see logs and check configuration

在任何人建议之前，这种测试在本地工作（并且在本地工作了很长时间）。以下是示例输出的一部分：

我该如何解决这个问题？我是否应该创建自己的基础映像，其中安装了maven和docker？我可以轻松地修改容器以在容器中使用apt get吗？欢迎提出任何建议，但我希望docker和maven都能提供，因为它们都在我的技术堆栈中，并且正在工作——只是gitlab配置问题。 以下是gitlab上的项目位置：

虽然我当然欢迎对项目其他部分的评论，但这些评论应该通过电子邮件发送给我，以保持此页面的整洁（不要放在这里）

对于任何想知道的人：您可以通过在CI/CD配置中添加一些变量来解决此问题

我补充的是：

MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"  
#these were added to try and get test containers to work -- if it doesnt, can remove below two
DOCKER_HOST: "tcp://docker:2375"
DOCKER_DRIVER: "overlay2"

没关系，我可以通过添加几个变量来解决我自己的问题：）没关系，我可以通过添加几个变量来解决我自己的问题：）
