Docker Container无法访问本地主机端口4444。为什么?
我将一个应用程序容器化,该应用程序是自动selenium测试的测试驱动程序。Selenium服务器(也称为Selenium
Hub)在localhost:4444下的另一个Container和Firefox Node中运行。但是我的应用程序无法达到它:
Build info: version: 'unknown', revision: 'unknown', time: 'unknown'System info: host: '10d3b5fd1010', ip: '172.17.0.2', os.name: 'Linux', os.arch: 'amd64', os.version: '3.16.0-4-amd64', java.version: '1.8.0_11 1'

Caused by: org.apache.http.conn.HttpHostConnectException: Connect to localhost:4444 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: C onnection refused (Connection refused)

我通过docker-compose启动了这些容器:
version: '2'services:
hub:
image: selgrid:1.1
ports:
- "4444:4444"
firefox:
#pull latest from docker hub
image: selenium/node-firefox
volumes:
- /dev/urandom:/dev/random
depends_on:
- hub
environment:
- HUB_PORT_4444_TCP_ADDR=hub
- HUB_PORT_4444_TCP_PORT=4444
testautomation:
#run testautomation app
image: volumetest
links:
- "hub"
ports:
- "9005:9005"
我想我的docker-compose中有一个错误,但我无法弄清楚。请帮忙!顺便说一句:我正在Windows 7上运行,并将Docker与Vagrant
VM配合使用。在我的Vagrantfile中,我将端口4444和9005映射到了主机系统。如果打开本地浏览器并访问localhost:4444,则可以看到selenium网格控制台。为什么从我的应用程序容器中不起作用?
回答:
在您的应用程序容器中localhost
是指当前容器。因此,您需要改用服务名称。您的情况是hub
所以连接到 hub:4444
