Google chrome 镀铬无头罐'；在docker compose中无法访问网络上的URL,google-chrome,docker,docker-compose,google-chrome-headless,Google Chrome,Docker,Docker Compose,Google Chrome Headless,问题的简要描述如下：我有docker compose设置和两个服务：app和test 我可以在test中获得chrome headless以访问公共URL 我可以让test成功卷曲到app 但是我无法让测试加载docker上用chrome headless组成网络的URL 我有一个docker compose文件，其中包含两个服务，如下所示： version: '3' services: app: build: context: . dock

问题的简要描述如下：

我有docker compose设置和两个服务：
```
app
```
和
```
test
```
我可以在
```
test
```
中获得chrome headless以访问公共URL
我可以让
```
test
```
成功卷曲到
```
app
```

但是我无法让

测试加载docker上用chrome headless组成网络的URL


我有一个docker compose文件，其中包含两个服务，如下所示：
version: '3'
services:
  app:
      build:
        context: .
        dockerfile: App.Dockerfile
      ports:
        - 5000:5000
      restart: always
  test:
    build:
        context: .
        dockerfile: Chrome.Dockerfile
    depends_on:
      - app

安装Chrome的方式如下：
FROM node:8-slim

RUN apt-get update --fix-missing && apt-get -y upgrade
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
    && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' \
    && apt-get update \
    && apt-get install -y google-chrome-unstable --no-install-recommends \
    && rm -rf /var/lib/apt/lists/* \
    && rm -rf /src/*.deb

ADD entrypoint .
CMD ./entrypoint

入口点脚本如下所示：
#!/bin/bash

因此，如果curl工作，而chrome headless工作，为什么chrome headless不能加载http://app:5000
URL
下面是一份完整的回购协议，它说明了问题：
注1：libudev:udev\u在/dev:Operation not allowed
上有\u devtmpfs:name\u to \u handle\u可能是相关的，我可以用cap add sys\u admin等几种方法解决这个问题，但似乎没有任何效果
注2：关于错误：ssl\u client\u socket\u impl
，该应用程序没有公开ssl，因此这是意料之中的（我想）。
我还不能确切说明原因，但将服务名称从应用程序更改为应用程序
以外的其他名称可以修复它：

版本：“3”
服务：
其他：
建造：
上下文：。
dockerfile:App.dockerfile
端口：
- 5000:5000
重新启动：始终
测试：
建造：
上下文：。
dockerfile:Chrome.dockerfile
取决于：
-其他

显然，Chrome（至少以我的设置方式）处理http://app:5000/
与http://other:5000
