【问题描述】：
我正在尝试使用 Docker 映像“postgis/postgis:latest”作为 GitLab CI 中的服务，但该服务无法启动。
这是 CI 日志的开头，最后一行是最重要的：

无法将主机名“postgres”转换为地址：名称或服务未知
在我看来，主机“postgres”是错误的。但是 GitLab 的文档说主机名将是别名：https://docs.gitlab.com/ce/ci/docker/using_docker_images.html#accessing-the-services
我的 .gitlab-ci-yml 的摘录：
image: node:lts-stretch
services:
- name: redis:latest
- name: postgis/postgis:latest
alias: postgres
variables:
NODE_ENV: production
REDIS_HOST: redis
POSTGRES_DB: postgres
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
PGHOST: postgres
PGUSER: postgres
PGPASSWORD: postgres
我还尝试删除别名并根据文档使用“postgis-postgis”或“postgis__postgis”作为主机名，但每次都出现相同的错误。我也尝试使用 docker 镜像“mdillon/postgis”，因为我经常看到它，但也出现同样的错误。
