初始任务
在我的 GitLab CI 构建中，我想要：
- 使用本地 AmazonDB 启动 Docker 容器。标准端口布局：端口
8000在码头工人，港口8000裸露。当然，一切都在本地运行，我可以连接（curl, awc-cli、Amazon DB 的 Java 代码，无论您想要什么）。
- 使用它进行测试，即连接到它
--endpoint-url http://localhost:8000（或任何其他映射的 IP，而不是localhost).
Problem
.gitlab-ci.yml看起来像这样：
image: docker:stable
build/test:
tags:
- gradle
- eu
stage: test
# doesn't work with or without it
# services:
# - docker:dind
script:
# display local running containers
- echo Displaying all running docker containers with "amazon/dynamodb-local" image...
- docker ps --filter ancestor=amazon/dynamodb-local
# stop all running docker containers with "amazon/dynamodb-local" image
- echo Stopping all Docker containers with "amazon/dynamodb-local" image...
- CONTAINERS=$(docker ps -q --filter ancestor=amazon/dynamodb-local)
- >
if [ "${CONTAINERS}" == "" ]; then
echo No docker containers with "amazon/dynamodb-local" image running. Nothing to stop.
else
docker stop $(docker ps -q --filter ancestor=amazon/dynamodb-local)
echo All Docker containers with "amazon/dynamodb-local" image stopped.
fi

fi
# display local running containers
- echo Displaying all running docker containers with "amazon/dynamodb-local" image...
- docker ps --filter ancestor=amazon/dynamodb-local
关键执行点（Gitlab-CI 日志）如下所示：
Docker 容器运行：
$ docker run --detach -p 8000:8000 amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb
c823489c22fffa603c1ae1b91d898cb7de4964774d54a08c9fdf0b891c2243b4
$ echo Displaying all running docker containers with "amazon/dynamodb-local" image...
Displaying all running docker containers with amazon/dynamodb-local image...
$ docker ps --filter ancestor=amazon/dynamodb-local

c823489c22ff amazon/dynamodb-local "java -jar DynamoDBL…" 1 second ago Up Less than a second 0.0.0.0:8000->8000/tcp peaceful_beaver
卷曲失败（尝试了所有可能的变化，这只是一个例子）：
$ curl localhost:8000 | true
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0

curl: (7) Failed to connect to localhost port 8000: Connection refused
Authenticating with credentials from $DOCKER_AUTH_CONFIG
ERROR: Job failed: exit code 7
我尝试过有和没有
services:
- docker:dind
尝试使用主机名localhost or docker or tcp://localhost, with http://前缀或不带前缀，带端口80, 8000 or 2375。什么都不起作用。
的价值${DOCKER_HOST} is unix:///var/run/docker.sock:
$ echo docker host is ${DOCKER_HOST}
docker host is unix:///var/run/docker.sock
/etc/hosts不包含别名docker
$ cat /etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.3 runner-H3HL9s9t-project-913-concurrent-0
问题
- 如何解决这个典型任务？
- 是否可以解决
docker run，或复杂的docker-compose需要使用。
- 有工作示例的链接吗？
- 有问题吗，没有
docker别名在/etc/hosts?
- Is
unix:///var/run/docker.sock有效值为${DOCKER_HOST}？这个变量的值不应该设置在variables of .gitlab-ci.yml（特别是对于tcp://localhost:2375)?
Links
我用谷歌搜索了多个链接。那里的解决方案目前对我没有帮助。
