简而言之，有一个额外的容器作为测试运行器，它不能到达selenium-hub。因此，测试失败。
添加此容器用于使用云构建在云上运行测试。
我创建的docker-compose如下:
version: "3"
services:
selenium-hub:
image: selenium/hub:4.0.0-rc-1-prerelease-20210804
container_name: selenium-hub
ports:
- "4444:4444"
expose:
- 4444
chrome:
image: selenium/node-chrome:4.0.0-rc-1-prerelease-20210804
shm_size: 2gb
depends_on:
- selenium-hub
environment:
- SE_EVENT_BUS_HOST=selenium-hub
- SE_EVENT_BUS_PUBLISH_PORT=4442
- SE_EVENT_BUS_SUBSCRIBE_PORT=4443
ports:
- "6900:5900"
chrome_video:
image: selenium/video:ffmpeg-4.3.1-20210804
volumes:
- /Users/videos:/videos
depends_on:
- chrome
environment:
- DISPLAY_CONTAINER_NAME=chrome
- FILE_NAME=chrome_video.mp4
容器开始工作成功后，当我运行npm run test运行selenium js测试时，我得到了成功的结果，并在预期的目录中录制了视频。但它也应该是自动化的。npm run test应该被触发。
在我们的CI/CD过程中，cloudbuild。为在云上运行添加了Yaml文件。
steps:
- name: 'docker/compose:1.29.2'
args: ['run','test']
- name: 'docker/compose:1.29.2'
args: ['stop']
timeout: 60s
云构建应该触发下面添加到docker-compose文件中作为测试运行器的新容器:
test:
image: node:16-alpine
entrypoint:
- sh
- -c
- |-
cd /test
npm install
sleep 3
npm run test
volumes:
- .:/test
depends_on:
- selenium
network_mode: host
但是对于测试容器，测试失败并得到以下错误:

关于当前网络:
>> % docker network inspect -v host

测试节点似乎无法到达127.0.0.1:4444
我该怎么做才能解决这个问题?如果能听到其他的解决方案就好了。
提前感谢。
在运行测试之前需要等待网格准备好。我在项目的README中记录了一些方法，请查看https://github.com/seleniumhq/docker-selenium/#waiting-for-the-grid-to-be-ready
